FAQ from live webcast

Only the uBR10k CMTS platform supports the SIP and SPA modules.
The SIP needs to be installed in Slots 1, 2, 3, or 4 of the Cisco uBR10k router (referred to as WAN slots).
The SPA's would then be installed into the SIP.
The various SPA's available are:
Cisco Wideband SPA - For Wideband / M-CMTS solutions.
1-Port 10-Gigabit Ethernet Shared Port Adapter - For network connectivity
5-Port Gigabit Ethernet Shared Port Adapter - For network connectivity
Here is an excerpt from the Cisco uBR10012 Universal Broadband Router SIP and SPA Software Configuration Guide:
http://www.cisco.com/en/US/docs/interfaces_modules/shared_port_adapters/configuration/ubr10012/12.3_23_bc/sipsp_d3.html
SPA Interface Processors (SIP)
A SIP is a carrier card that inserts into a router slot like a line card. It provides no network connectivity on its own.
A SIP contains one or more bays (subslots), which are used to house one or more SPAs. The SPA provides interface ports for network connectivity.
During normal operation the SIP should reside in the router fully populated either with functional SPAs in all bays, or with a blank filler plate (SPA-BLANK=) inserted in all empty bays.
SIPs support online insertion and removal (OIR) with SPAs inserted in their bays. SPAs also support OIR and can be inserted or removed independently from the SIP.
Shared Port Adapters (SPA)
A SPA is a modular type of port adapter that inserts into a bay of a compatible SIP carrier card to provide network connectivity and increased interface port density. A SIP can hold one or more SPAs, depending on the SIP type.
SPAs are available in various types. The Cisco Wideband SPA is a single-wide, half-height SPA. Figure 2-1 shows how bays are numbered on the Cisco Wideband SIP.

Configuring and Troubleshooting Virtual Switching System (VSS)

With Anand Ganesan
Welcome to the Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about how to monitor, configure, and troubleshoot the Virtual Switching System (VSS) in Cisco Catalyst 6500 Series Switches with expert Anand Ganesan.
VSS is network system virtualization technology that pools multiple Cisco Catalyst 6500 Series Switches into one virtual switch, increasing operational efficiency, boosting nonstop communications, and scaling system bandwidth capacity to 1.4 Tbps. At the initial phase, a VSS will allow two physical Cisco Catalyst 6500 Series Switches to operate as a single logical virtual switch called a virtual switching system 1440 (VSS1440).
For more information, visit: www.cisco.com/en/US/prod/collateral/switches/ps5718/ps9336/prod_qas0900aecd806ed74b.html
The VSS simplifies network configuration and operation by reducing the number of Layer 3 routing neighbors and by providing a loop-free Layer 2 topology.

My questions revolve around the same point.
Are there any significance in running eigrp or any other routing protocol over this BFD link?
Is the Dual active scenario detected by BFD or BFD notifies a routing protocol like eigrp and in turn dual active is detected?
Should I suppress the eigrp HELLOs on these interfaces to get rid of the log message?

Hello Krzysztof,
Another set of good/interesting questions posted. Thanks!
I will try to clarify your doubts.
In the output below both resources (proxy-connections and ssl-connections rate) are configured with a min percentage of resources (column Min), while 'Max' is set to equal to the min.
ACE/Context# show resource usage
                                                     Allocation
        Resource         Current       Peak        Min        Max       Denied
-- outputs omitted for brevity --
proxy-connections             0      16358      16358      16358      17872
ssl-connections rate          0        626        626        626      23204
Most columns are self explanatory, 'Current' is current usage, 'Peak' is the maximum value reached, and the most important counter to monitor 'Denied' represents the amount of packets denied/dropped due to exceeding the configured limits.
On the resources themselves, Proxy-connections is simply the amount of proxied connections, in other words all connections handled at layer 7 (SSL connections are proxied, as are any connections with layer 7 load balance policies, or inspection).
So in this particular case for the proxy-connections we see that Peak is equal to the Max allocated, and as we have denies we can conclude that you have surpassed the limits for this resource. We see there were 17872 connections dropped due to that.
ssl-connections rate should be read in the same manner, however all values for this resource are in bytes/s, except for Denied counter, that is simply the amount of packets that were dropped due to exceeding this resource.
For your particular tests you have allocated a min percentage and set max equal to min, this way you make sure that this context will not use any other additional resources.
If you had set the max to unlimited during resource allocation, ACE would be allowed to use additional resources on top of those guaranteed, if those resources were available.
This might sound a great idea, but resource planning on ACE should be done carefully to avoid any sort of oversubscription, specially if you have business critical contexts.
We have a good reference for ACE resource planning that contains also description of all resources (this will help to understand the output better):
http://www.cisco.com/en/US/docs/interfaces_modules/services_modules/ace/v3.00_A2/configuration/virtualization/guide/config.html#wp1008224
1) When a resource is utilized to its maximum limit, the ACE denies additional requests made by any context for that resource. In other words, the action is to Drop. ACE should in theory silently drop (No RST is sent back to the client). So unless we changed something on the code, this is what you should see.
To give more context, seeing resets with SSL connections is not necessarily synonym of drops. As it is usual to see them during normal transactions.
For instance Microsoft servers are usually ungracefully terminating SSL connections with RESET. Also when there is renegotiation during an SSL transaction you may see RESETS, but this will pass unnoticed for end users.
2) ACE will simply drop/ignore new connections when we reach the maximum amount of proxied connections for that context. Exisiting connections will continue there.
As ACE doesn't respond back, client would simply retransmit, and if he is lucky maybe in the next attempt he will be able to establish the connection.
To overcome the denies, you will definitely have to increase the resource allocation. This of course, assuming you are not reaching any physical limit of the box.
As mentioned setting max as unlimited might work for you, assuming there are a lot of unused resources on the box.
3) If a new connection comes in with a sticky value, that matches the sticky entry of a real server, which is already in MAXCONNS state, then both the ACE module/appliance should reject the connection and that sticky entry would be removed.
The client would at that point reestablish a new connection and ACE would associate a new sticky entry with the flow for a new RSERVER after the loadbalancing decision.
I hope this makes things clearer! Uff...
Regards,
Telmo

Ask the Expert:Concepts, Configuration and Troubleshooting Layer 2 MPLS VPN – Any Transport over MPLS (AToM)

With Vignesh R. P.
Welcome to the Cisco Support Community Ask the Expert conversation.This is an opportunity to learn and ask questions about concept, configuration and troubleshooting Layer 2 MPLS VPN - Any Transport over MPLS (AToM) with Vignesh R. P.
Cisco Any Transport over MPLS (AToM) is a solution for transporting Layer 2 packets over an MPLS backbone. It enables Service Providers to supply connectivity between customer sites with existing data link layer (Layer 2) networks via a single, integrated, packet-based network infrastructure: a Cisco MPLS network. Instead of using separate networks with network management environments, service providers can deliver Layer 2 connections over an MPLS backbone. AToM provides a common framework to encapsulate and transport supported Layer 2 traffic types over an MPLS network core.
Vignesh R. P. is a customer support engineer in the Cisco High Touch Technical Support center in Bangalore, India, supporting Cisco's major service provider customers in routing and MPLS technologies. His areas of expertise include routing, switching, and MPLS. Previously at Cisco he worked as a network consulting engineer for enterprise customers. He has been in the networking industry for 8 years and holds CCIE certification in the Routing & Switching and Service Provider tracks.

Hi Tenaro,
AToM stands for Any Transport over MPLS and it is Cisco's terminology used for Layer 2 MPLS VPN or Virtual Private Wire Service. It is basically a Layer 2 Point-to-Point Service. AToM basically supports various Layer 2 protocols like Ethernet, HDLC, PPP, ATM and Frame Relay.
The customer routers interconnect with the service provider routers at Layer 2. AToM eliminates the need for the legacy network from the service provider carrying these kinds of traffic and integrates this service into the MPLS network that already transports the MPLS VPN traffic.
AToM is an open standards-based architecture that uses the label switching architecture of MPLS and can be integrated into any network that is running MPLS. The advantage to the customer is that they do not need to change anything. Their routers that are connecting to the service provider routers can still use the same Layer 2 encapsulation type as before and do not need to run an IP routing protocol to the provider edge routers as in the MPLS VPN solution.
The service provider does not need to change anything on the provider (P) routers in the core of the MPLS network. The intelligence to support AToM sits entirely on the PE routers. The core label switching routers (LSRs) only switch labeled packets, whereas the edge LSRs impose and dispose of labels on the Layer 2 frames.
Whereas pseudowire is a connection between the PE routers and emulates a wire that is carrying Layer 2 frames. Pseudowires use tunneling. The Layer 2 frames are encapsulated into a labeled (MPLS) packet. The result is that the specific Layer 2 service—its operation and characteristics—is emulated across a Packet Switched Network.
Another technology that more or less achieves the result of AToM is L2TPV3. In the case of L2TPV3 Layer 2 frames are encapsulated into an IP packet instead of a labelled MPLS packet.
Hope the above explanation helps you. Kindly revert incase of further clarification required.
Thanks & Regards,
Vignesh R P

Ask the Expert: Global Site Selector Configuration and Troubleshooting

Welcome to this Cisco Support Community Ask the Expert conversation. This is an opportunity to learn and ask questions about configuring and troubleshooting the Global Site Selector (GSS) with expert Swati Chopra.
GSS devices represent the next generation of application switches and global server load balancing (GSLB) appliances. Working together with the Cisco ACE Module and Cisco ACE 4710 appliance, these devices form an application-fluent networking solution that improves availability, acceleration, and security for data center applications.
The primary role of Cisco GSS is to implement the business continuance and disaster recovery policies of a business by optimizing and securing the Domain Name System (DNS) infrastructure of the data center. It does this by integrating with the DNS infrastructure and responding to the client DNS requests, thereby directing the client to the site that is best able to serve its needs.
Swati Chopra is a CCNA, CCNP, and VCP certified customer support engineer for content switching, covering technologies such as Cisco Application Control Engine, Cisco Wide Area Application Services, Global Site Selector, Cisco Content Services Switches, and Digital Media Suite. She has been with Cisco for more than three years and has worked with most of the high-end customers on content-related complex cases. She completed her master’s degree in finance, was heading an online education project in collaboration with e-Sylvan, and later moved to technical services because of her love for technology. She is actively involved with diverse Cisco initiatives such as Connected Women, WISE, and Cisco Career Connections and recently hosted a “Birds of Feather” table at Cisco’s Women of Impact conference.

Hi Sarah,
The load balancing mechanism for GSS requests is done via different methods. We can use these methods to define how the load is shared for different balance clauses within the same rule. The 6 methods we use are:
–round-robin—The GSS cycles through the list of answers that are available as requests are received. Each resource within an answer group is tried in turn. The GSS cycles through the list of answers, selecting the next answer in line for each request. This is the default.
eg: if we have 2 answers in answer group then GSS will provide them alternatively.
–least-loaded—The GSS selects an answer based on the load reported by each VIP in the answer group. The answer reporting the lightest load is chosen to respond to the request.The least-loaded option is available only for VIP-type answer groups that use a KAL-AP or Scripted keepalive, as they provide the GSS with detailed information on the SLB load and availability.
eg: if one answer has higher load than the other, than first answer will not be provided until its load goes down the other answers
–ordered—The GSS selects an answer from the list based on precedence; answers with a lower order number are tried first, while answers further down the list are tried only if preceding answers are unavailable to respond to the request.
for eg: answer with ordered number 1 will be provided first till it becomes unavailable. Once it is unavailable then answer with ordered list number 2 will be provided
–weighted-round-robin—The GSS cycles through the list of answers that are available as the requests are received, but sends requests to favored answers in a ratio determined by the weight value assigned to that resource.
eg: if one answer has more weight(80%) than the other answer(20%), then it will be used 8 times out of 10.
–hashed— When the GSS uses the hashed balance method, elements of the client's DNS proxy IP address and the requesting client's domain are extracted to create a unique value, referred to as a hash value. The unique hash value is attached to and used to identify a VIP that is chosen to serve the DNS query.
The use of hash values makes it possible to "stick" traffic from a particular requesting client to a specific VIP, ensuring that future requests from that client are routed to the same VIP. This type of continuity can be used to facilitate features, such as online shopping baskets, in which client-specific data is expected to persist even when client connectivity to a site is terminated or interrupted.
The GSS supports the following two hashed balance methods. You can apply one or both hashed balance methods to the specified answer group.
• By Source Address—The GSS selects the answer based on a hash value created from the source address of the request.
• By Domain Name—The GSS selects the answer based on a hash value created from the requested domain name.
for eg: a user using same source ip will get the same answer from GSS if we do source address hashing.
-DNS Race (Boomerang) Method-The GSS supports the DNS race (boomerang) method of proximity routing, which is a type of DNS resolution initiated by the GSS to load balance 2 to 20 sites.
The boomerang method is based on the concept that instantaneous proximity can be determined if a CRA within each data center sends an A-record (IP address) at the exact same time to the client's D-proxy. The DNS race method of DNS resolution gives all CRAs (Cisco content engines or content services switches) a chance at resolving a client request and allows for proximity to be determined without probing the client's D-proxy. The first A-record received by the D-proxy is, by default, considered to be the most proximate.
Use case is mainly with CRA's.
Hope this helps. Please feel free to revert if you have follow-up questions.
Thanks,
Swati

I appreciate your questions, and will try to answer them below.
When you are installing a fresh new MeetingPlace 8.5 that you plan to integrate with WebEx, the only available option is WebEx Managed user profiles. With this option, you can either create profiles manually on WebEx side, and then sync them to MeetingPlace, or you can use Federated SSO for import of profiles from LDAP server in your network to WebEx, and then sync the profiles from WebEx to MeetingPlace (you choose one of these two options when provisioning WebEx site).
These are the only two available options for a NEW install of MP8.5 for WebEx integration, and as you can see both options are WebEx Managed profiles, the only difference is if you are going to use Federated SSO, or create profiles on WebEx manually.
During the install, you can select to install MeetingPlace managed users option, but you would choose this option only if you plan to do a migration from an earlier MP release (7.x/8.0) with WebEx integration and Directory Integration.
For example, MeetingPlace managed profiles option is available if you had MeetingPlace 8.0 integrated with WebEx Type II (WebEx scheduling) with Directory Integration, where you had your MP8.0 integrated with CUCM via AXL for user profile management (CUCM integrated with LDAP), and your WebEx Site provisioned for Directory Integration, and then migrate from that system to MeetingPlace 8.5 that you installed selecting MeetingPlace managed user profiles.
The same goes for MeetingPlace Scheduling (Type I) integration with WebEx. Possible only with migration, and not with a fresh new installation.
Now, to focus on your questions.
1. As you can see, you don't have many options. If you have MS Active Directory that you would like to use for SSO in MP8.5 WebEx Scheduling, you will have to go with Federated SSO. So far, I haven't heard of any issues with that as it seems to be pretty straight forward to configure, and also WebEx Support team provides direct support for that setup as it is a direct integration between WebEx Site and the LDAP server (nothing to do with MeetingPlace side of the equation).
2. In general, if you have Federated SSO enabled, you would go to WebEx site home page, click on Host Log In button which will then ask you to enter your network/windows credentials and place you to WebEx scheduling interface.
If you have Directory Integration (like on MP8.0 WebEx Type II with CUCM/AXL integration), when you go to WebEx site home page and click Host Log In button, you are being redirected to the MeetingPlace log-in page where you would enter your Windows credentials (assuming your CUCM is integrated with LDAP), and then if log in is successful, you get redirected back to WebEx scheduling interface. With this type of deployment, you can log in to WebEx scheduling interface ONLY if you are connecting from your company network or have a VPN connection to your company network. This is a major limitation that most customers complained about, but the reason for this was that we didn't want to make MP Application server hostname/IP publicly available and hence cause a security issue.
I am sure I answered your questions, but opened some new questions. So, please, let me know if I need to clarify anything.
Thank you.

Configuring Solaris 8 Sparc w/router and cable modem

I recently purchased a Sun Ultra 10 with Solaris 7
pre-installed. I decided to immediately upgrade to
Solaris 8. The operating system has installed properly
so far.
However, I'm at the point now where I am entering
information to allow Solaris to connect to my network
and thus the Internet, and the combinations I have tried
don't work.
I use a cable modem service with a Netgear RT314
four-port router. It functions in a standard way - the
cable modem is 192.168.0.1 and shows up on my
WinXP PC (in ipconfig /all) as the DNS server and
gateway server. On the PC, for "Connection-specific
DNS suffix", I see nc.rr.com (my ISP).
Solaris 8 wants to know my domain name, as well as
my DNS server. I don't know what domain name to give
it. I have tried nc.rr.com, but when I enter that plus
192.168.0.1 as the DNS server, I end up receiving this
message: ""Unable to find an entry for dchppc3 with the
specified DNS configuration."
I have been afraid to move beyond this point, although
it's possible that it will work properly and just isn't
receiving the confirmation it expects.
Any suggestions would be welcome, either in this forum
or emailed to me. My address is [email protected]
Thanks.

I decided to plow ahead with the installation. It works
properly within my local network - I can ping dchp
addresses and view Web files from my local server
using 192.168.0.3 (that machine's dchp address).
However, it can't get to the Internet. So my problem
now is that I can see the router, but can't see the
Internet services that the router provides to the other
computers on my network. Presumably, I need to
alter my DNS settings ... however, on my PCs, I seem
to simply use the router (192.168.0.1) as the DNS, and
it properly passes the request along to my cable modem
provider. Why would this work for the PCs but not for
Solaris 8? Thanks -

Connecting Motorola SB6121 Cable Modem and AirPort Extreme

I moved into a new house a couple of days ago so of course the first thing that I needed to do was get the home wireless up and running. My ISP is through Comcast. I purchased my own cable modem (Motorola SB6121) instead of renting and used my own AirPort Extreme as the wireless router.
First, if you're purchasing your own cable modem, you will need to contact your ISP and provide them with the HFC MAC ID on the cable modem. Once you've gone through the motions, you will be able to connect your Mac (in my case Macbook) directly to the modem via ethernet cable and access the internet.
Issue:
When I connected the SB6121 to the AE, I could connect wirelessly to the AE, but I did not have access to the internet. So, basically the SB6121 and the AE were not talking to each other despite being physically connected via ethernet cable.
Solution:
After days of searching for online answers and forums (and trying different solutions) I was able to successfully get everything up and running. Make sure that you have 2 ethernet cables available.
Here are the steps.
I restored my AE to factory settings just to keep everything simple. Here are instructions: http://support.apple.com/kb/HT3728 Once you've restored your AE, make sure that both the AE and the cable modem are unplugged from their power sources.
Plug in the power to the SB6121.
Connect your SB6121 directly to your laptop via Ethernet cable. Test to ensure that you have internet accessibility by going to any website.
Remove the ethernet cable from your laptop and plug it into the "internet in" jack in the back of the AE.
Power up the AE.
Connect your laptop to the back of the AE using ethernet cable #2.
Launch a browser. You should now be able to successfully connect to any website.
Assuming that you reset your AE to factory settings, it should just be broadcasting the generic "Airport Extreme" SSID. Disconnect the ethernet cable and connect using wireless to the SSID. Launch a browser and you should be able to connect to the internet.
You can now use the AirPort Utility to configure the AirPort settings.
I assume that this solution would work with any of the base stations.

I was having the exact same issue tonight. Just purchased the AE Model A1408 and haven't been able to maintain an internet connection on my iMac whenever I tried hooking it up via the Airport Utility application. So after I had the SB6121 connected to the AE and the AE connected to my PC with no luck, I then went to the Network icon in System Preferences. Clicked on "Assist me...". Then clicked on "Diagnostics..." and followed the directions which basically had me first power down the SB6121 modem and power it back up. Then I powered down the AE router and powered it back up. At that point I was now getting an internet connection. I then took my ipad 2 and went to the Wi-Fi settings and noticed it was asking me to setup a network through my AE. I selected that and went through the simple steps to set up the network and password and now it all works. I am a novice so don't ask me why but I now get a green solid light on my AE. I can connect other devices wirelessly. I can still access the internet on my iMac. For whatever reason, using the Airport Utility on the iMac doesn't work in my case and using my ipad to set up the wireless network did the job.

SurfBoard Cable Modems and OS X

I just wanted to post a message about my findings and my solution to the Mototrola SurfBoard 5101 Cable modem. I use comcast as my ISP. I was using an old COM21 modem. I was getting around 4300 KBPS on a broadband test from Speakeasy. Since Comcast was starting this PowerBoost, I needed a DOCSIS 1.1 compliant modem and the COM21 modem wasn't. I went to my localComcast office to switch it out since I was leasing one. They gave me a SurfBoard 5101. I already saw the postings and the articles on Macfixit.com. I tried the modem and was getting 2700 Kbps. I tried everything to get the speed better. Connecting my iMac directly to the modem. Tweaking TCP settings.
I called Comcast and they said they never heard of the issue. I explained of all the postings I saw and the artiles also. She said she believed me but didn't know of the problem. I found one article talking about using other modems. The newer Surfboard 5120 modem said was better but had issues with Comcast's network and would disconnect. They said the linksys cable modem wasn't any better. The one they said was the best was the DLINK DCM-202. It was 49.95 on sale at Best Buy. I thought, what the ****, I'll try it. If it didn't work I can return it. I got it home. Installed it. Provisioned it and ran the Speakeasy tests. I was blown away. I got a speed of 9049 Kbps. Just ran the test while typing this.
So if anyone else having this issue, I would return the cable modem back to Comcast and ask for a non Motorola modem. That's the advice the Comcast rep told me. Or just buy the DLINK modem. I can now return the 5101 modem and stop leasing it and finally I get my full speed.
Thanks!!!

I used telewest's 10 megabit cable service here in the London UK for about a year. they issued me with a motorola surboard SB 5100i and this worked perfectly. I could get the max download speed of 1.2 megabytes per second and an upload speed of 400k.
I used the cable modem with a linksys wrt54gs router and has not bandwidth issues at all.
I did not have to tweak any network settings on my Macs.

Please help me connect eMac, cable modem, and Airport Extreme Base Station

I connected Ethernet cord from cable modem to Airport Extreme Base Station and then another Ethernet cord from Airport Extreme Base Station to eMac, but I could not get internet access on my eMac that way. I'm only getting internet access by directly connecting eMac to cable modem. Can someone please help me with a step by step explanation of how to set these 3 machines up so that I can have internet access on both my eMac and, wirelessly, on my new MacBook. Thank you very much in advance.

jenngee, Welcome to the discussion area!
Ensure that you power off the cable modem for a minute or so when you switch it to another Ethernet device.
Ensure that you are connecting the WAN port of the AirPort Extreme base station (AEBS) to the cable modem. The eMac should connect to the LAN port.
The steps for setting this up can be found in the "Designing AirPort Networks" (direct PDF link) document. Look through that document and try to get it setup. Then return here if you have more questions. Don't forget to post what you tried and the issues you encountered.

EA4500 Won't get a DHCP WAN address from Cable Modem

I have an EA 4500 that I used to replace a bad WRT45 (or something like that). We have an ADT camera system that allows you to view the cameras locally and remotely. All I have to do is set a static internal address on the DVR and the public IP on the router in the application. I duplicated the setting in the old router and everything was running smoothly. However, the speed test result I was getting from the router and speedtest.net were not even close to what we were paying for (wireless and wired. But it was functional.
I called Comcast and they said we needed a Docsis 3 modem. So, I went to the Comcast office and they traded out my modem for a docsis 3. Hooked it up and everything was working again. Speeds were better but not really up to par. Hooked my laptop directly into the new modem and I was getting speeds off the charts. Frustrated, I called Comcast, they said the modem needed to be put in Bridge mode. Then the EA4500 wouldn't get a DHCP WAN adress. They took it out of bridge mode. Same result.
They sent a tech out (Mind you I've been a Network Engineer for almost 20 yrs) and he tells me they gave me the wrong modem (I wasn't there either, roommate let him in). He replaced the modem with a new all inclusive router/switch/wifi modem. He then proceeds to setup a whole new network, which of course , except the laptops that connected, my devices don't see ( printers, cameras, dvr, etc). Then, this baffles me... he did a factory reset on my EA4500. So now there are 2 seperate networks one with slow Internet and one without WAAN services.
After all this, my EA4500 still will not get a WAN address when plugged into the new modem. I would just use their new modem but to make any config changesto it, something as simple as changing the SSID name or the password, you have to call them. They won't give you access to the admin page.
Anyone have any ideas why my EA4500 won't get a WAN address? Oh, btw, I did do a MAC address clone on the EA4500 while connected to the modem and it DID get the address, but the speeds were dismal, not even 1mb up or down.

@stix180
There is a need to reset and reconfigure the EA4500 router to work with the new modem. There are certain configurations on the router that will make it work for a particular modem, and this might be causing the issue. Cable modem authenticates end users through username and password but there are cable modem/router as well in which the IP address are on the same range with the default IP address of the router. Please try to check the IP address of the computer wired directly to your modem, it should not be on the same IP address range with the EA4500 router since it will cause IP address conflict. You can change the default IP address of your router from 192.168.1.1 to 10.10.10.1. Please try to make sure that your router also has the latest firmware version installed. And it would help if you do port forwarding on the router for your camera and DVRs to resolve NAT issues.

Multiple routers/networks on one cable modem

Hello everyone:
I've been reading around on the forum trying to find the answer to this question, but have not found any specific answer that satisfies all my requirements. A more in-depth explanation.
I have 1 IP address via cable modem. I want to configure two wireless routers each with different SSIDs. The main network would be an Apple Time Capsule and would be the parent’s network. I would connect an AppleTV and the second router (Linksys WRT-310N) to the LAN ports and the parents’ phones/tablets and an Airport Express extender wirelessly. The second router would provide a distinct wireless network, have a DVR, network hard drive, and blu-ray player connected to the LAN ports and the kids’ handheld devices and a wifi printer connected wirelessly.
Ideally, both networks would use WPA2 security and the parents’ computers, a Mac and a Win (the Win running Network Magic Pro) could manually switch between networks as necessary.
Can someone please tell me if this is possible? I think it is based on my research, but specific details about how to do it would be appreciated.
EQUIPMENT
Modem: Motorola SurfBoard SB6121
Router 1: Apple Time Capsule
Wireless Extender: Apple Airport Express
Router 2: Linksys WCG-310N

The new modem is configured to only hand out one public IP Address. Nothing you can do but call them and try to get a higher level tech support.

Problem Connecting Linksys WRT54G to Arris TM402P/100 Cable Modem

The Problem
Cannot get an internet connection attempting to install a Linksys WRT54G router between an Arris TM402P/100 cable modem and the local network.
Prior Configuration
Previously had DSL, with the Linksys WRT54G wireless router between the DSL modem and the local network, which worked perfectly.
New Configuration
This friend recently changed his broadband from DSL to Comcast cable, and he also has phone and television service over the same connection. The installation tech connected the cable modem directly to a desktop computer and left the Linksys router out.
The direct connection between the cable modem and the computer works fine, but he and his wife each have laptops and would like to us the Linksys router to connect wirelessly.

I cannot find a configuration on the Linksys WRT54G that will allow me to connect to the internet through the Arris TM402P/110 modem. Have tried (1) setting the Linksys to use a dynamic WAN address, (2) setting the Linksys to static IP 67.185.155.0 with TCP/IP settings taken from the above configuration, (3) cloning the MAC address of the desktop computer's NIC and trying both (1) and (2) again.
The error message says that the network cable is not connected. Is it possible that the connection between the router and cable modem requires a cross-over cable?
Any suggestions?

on the router's ui... keep the internet type to dhcp....clone the mac address and then do a power cycle...ensure that the modem is completely powered off during the power cycle...if you have a battery back - up , remove the battery...after a minute , put back the battery and then plug in the power cable in the modem...
let me know if this helps you....

Two Routers off One Cable Modem?

Can I run two routers off one cable modem, one a hardwired Windows network and the other an Airport Extreme networking a Powerbook G4 and wireless printer?

No you cannot - unless you pay your cable internet service provider for two public IP addresses.
What I would suggest if you already have the base station but have not yet purchased the router:
- connect the cable modem to the Base Station's WAN port
- buy a 4- or 8-port ethernet switch. Connect to the switch the LAN port of the Base Station, and all of your hardwired PCs
What I would suggest if you already have a router and base station:
- connect the cable modem to the router's WAN port
- connect all the hardwired PCs to the router's LAN ports
- connect the Airport Base Station to one of the router's LAN ports, and configure the Base Station to function as a wireless access point per http://discussions.info.apple.com/webx/.59976caa
