New VLAN config on Cisco router

We are in the process of rolling out VOIP with new Cisco router
configurations. When the VLAN config is changed on the router it can no
longer ping the server. The router config is setup with secondary IP info
so that we don't have to go thru the process of changing IP config on the
NW 6.5 SP 6 servers.
Has anyone seen this issue? Do I need to bind new VLAN ti IP NICs? Any
other thoughts?
Thanks for any help received,

When pinging from the router, the packets will be source from its primary
ip address. If the server's subnet is part of the secondary IP address on the
router, you must use an extended ping in the router for it to work.
However, I recommend implementing router-in-a-stick instead of secondary IP
addressing when creating multiple VLANs.
On the router, you can create sub-interfaces under the LAN interface and deploy
dot1q trunking. At the switch-port, configure dot1q trunking as well and the
router
will route between VLANs while providing a better design.
This is outside of the scope of this forum so I recommend posting in the Cisco
forums at http://forum.cisco.com/eforum/servlet/NetProf?page=main
Thanks !

Vlans and cisco router

I have a netgear managed switch and a cisco 1750 router. I would like to set up 2 vlans. the first one is a wan, with a residential cable model connected to it. the other vlan is for my private lan. I will then have the cisco router connected to one port on the switch set up as a trunk. I'm no pro, but from what I've read so far, it should work that way, right? the part I need help with is setting up the cisco router as a gateway and dns proxy, accepting the dynamic ip, gateway, and dns addresses from the cable modem.
I did see this http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Network%20Infrastructure&topic=Getting%20Started%20with%20LANs&CommCmd=MB%3Fcmd%3Ddisplay_location%26location%3D.1ddcef50
router in a stick *write that down* so my setup should work if I can figure out the router configuration. a good online tutorial or something would be helpful for this. I have plenty of cisco books, but maybe something for dummies would help me get started, before digging into the tough stuff.

In order to set up inter vlan routing or a "router on a stick" with a netgear switch you will need a router that supports IEEE 802.1q VLAN Support.
http://www.cisco.com/univercd/cc/td/doc/product/software/ios120/120newft/120t/120t1/8021q.htm#28767
On the router interface that is "trunked" to the switch you will need to have a configuration that looks like the what I have below.
Router(config)#interface FastEthernet0/1.1
Router(config-subif)#encapsulation dot1Q 1 native
Router(config-subif)#ip address 10.xx.xx.16 255.255.255.xxx
Router(config-subif)#interface FastEthernet0/1.2
Router(config-subif)#encapsulation dot1Q 2
Router(config-subif)#ip address 10.xx.xx.130 255.255.255.xxx
The sub-interface 1."2" corresponds to the vlan id on the trunk. In this case the .2 is vlan 2.
I have attahced a link that exlains the intricate details on inter vlan routing below:
http://www.cisco.com/warp/public/473/50.shtml
Lastly you may want to check the Cisco IOS feature Navigator. I was looking at it and I did not see that the 1750 has IEEE 802.1q VLAN Support. It looks like the 1751 is the first platform in the 1700 series that does.

How do you reset the hp 6300 series ip address to connect toa new Cisco router?

I am running on Windows 7 64-bit and cannot get the printer to hook up to the new router and work on my Homegroup to share the printer. It shows a error code and says to troubleshoot. It won't hook up to the CISCO router via ethernet cable.

On the front of the printer: Setup > Network > Restore Defaults.

Creating VLAN on our Cisco 300 series router

I am wanting to create separate VLANs on our Cisco 300 series switches, but I am struggling to find any decent examples out there.
Our basic infrastructure is
Router with
192.168.1.1 VLAN1
192.168.2.1 VLAN2
The switch is set up on ports 2345 for VLAN2
Port 1 is attached to the router on VLAN1 and VLAN2 assigned.
My problems seem to be that I really not sure what settings I should be using for each the ports to get this to work correctly

Hi,
Hope below link will have the information which you are looking for.
https://supportforums.cisco.com/document/140341/vlan-configuration-articles-sx200300-series-managed-switches
If you are looking for only vlan creation then below link will help.
http://sbkb.cisco.com/CiscoSB/Loginr.aspx?login=1&pid=2&app=search&vw=1&articleid=80
According to your above description you have connected the router to port 1 of switch and you have configured it as vlan 1...Should this port be trunk???

Vlan routing with cisco router and linksys switch

I have a linksys switch width vlan configured, connected to a Cisco router (1841), but I cant route between vlans.
Please help me!!
It Works with a Cisco switch perfectly(with the same ip and vlan).

Yes. the linksys switch (SRW2024 24-Port 10/100/1000 Gigabit Switch) supports trunking.
If you want you can visit the link and see that the switch supports vlan, dot1q and trunking.

Trouble connecting Cisco router with cable modem for Internet purposes

So I am requesting help from the Cisco community on this issue as the cable company states there equipment is working fine. At all my facilities I have a guest Internet service setup through a local Internet provide to provide Internet services to the residents and guests. I have the cable modem usually a Motorola SBG6580 or a SMC 8014 (both provided by cable company) connected to my router on a FE or GE interface. I am using static IPs and using the cable modem just as a modem (bridge mode). Over the past several months these connections have just stopped working. I have not made any drastic changes to my router configs; however, the cable company has updated the firmware on these modems. I am wondering if that could affected how the modem and router talk. I was told by the cable company that the modem sees the Cisco router but that the port is inactive. My router shows the port is active and traffic passing. Does anyone have any ideas that could point where the problem lies? I will post a basic config to one that currently does not work. I am using a VRF to route a certain group out, using NAT. Please let me know if I need to post additional info. Any help would be greatly appreciated.

Create 2 new VLANs and Trunk

Hi
I am working with a service provider to segment inbound traffic for a client. Rather than creating a seperate fibre circuit, we have opted for two new VLANs and a trunk to the upstream router.

I need to creat VLAN 2 and VLAN 3. Traffic currently running through VLAN 1 will be segmented between these two VLANs with a trunk to an upstream router.
vlan database commands don't appear to be working. At this stage I only want to create the VLANs. Can anyone recommend a command reference?

Not able to telnet or ssh to outside interface of ASA and Cisco Router

Dear All
Please help me with following question, I have set up testing lab, but still not work.
it is Hub and spoke site to site vpn case, connection between hub and spoke is metro-E, so we are using private ip for outside interface at each site.
Hub -- Juniper SRX
Spoke One - Cisco ASA with version 9.1(5)
spoke two - Cisco router with version 12.3
site to site vpn has been successful established. Customer would like to telnet/ssh to spoke's outside ip from Hub(using Hub's outside interface as source for telnet/ssh), or vise versa. Reason for setting up like this is they wants to be able to make configuration change even when site to site vpn is down. Sound like a easy job to do, I tried for a long time, search this forum and google too, but still not work.
Now I can successfully telnet/ssh to Hub SRX's outside interface from spoke (ASA has no telnet/ssh client, tested using Cisco router).
Anyone has ever done it before, please help to share your exp. Does Cisco ASA or router even support it?
When I tested it, of cause site to site vpn still up and running.
Thanks
YK

Hello YK,
On this case on the ASA, you should have the following:
CConfiguring Management Access Over a VPN Tunnel
If your VPN tunnel terminates on one interface, but you want to manage the ASA by accessing a different interface, you can identify that interface as a management-access interface. For example, if you enter the ASA from the outside interface, this feature lets you connect to the inside interface using ASDM, SSH, Telnet, or SNMP; or you can ping the inside interface when entering from the outside interface. Management access is available via the following VPN tunnel types: IPsec clients, IPsec LAN-to-LAN, and the AnyConnect SSL VPN client.
To specify an interface as a mangement-only interface, enter the following command:
hostname(config)# management access management_interface
where management_interface specifies the name of the management interface you want to access when entering the security appliance from another interface.
You can define only one management-access interface
Also make sure you have the pertinent configuration for SSH, telnet, ASDM and SNMP(if required), for a quick test you can enable on your lab Test:
SSH
- ssh 0 0 outside
- aaa authentication ssh console LOCAL
- Make sure you have a default RSA key, or create a new one either ways, with this command:
*crypto key generate rsa modulus 2048
Telnet
- telnet 0 0 outside
- aaa authentication telnet console LOCAL
Afterwards, if this works you can define the subnets that should be permitted.
On the router:
!--- Step 1: Configure the hostname if you have not previously done so.
hostname Router
!--- aaa new-model causes the local username and password on the router
!--- to be used in the absence of other AAA statements.
aaa new-model
username cisco password 0 cisco
!--- Step 2: Configure the router's DNS domain.
ip domain-name yourdomain.com
!--- Step 3: Generate an SSH key to be used with SSH.
crypto key generate rsa
ip ssh time-out 60
ip ssh authentication-retries 3
!--- Step 4: By default the vtys' transport is Telnet. In this case,
!--- Telnet and SSH is supported with transport input all
line vty 0 4
transport input All
*!--- Instead of aaa new-model, the login local command may be used.
no aaa new-model
line vty 0 4
login local
Let me know how it works out!
Please don't forget to Rate and mark as correct the helpful Post!

Site-to-Site VPN between Cisco ASA 5505 (8.4) and Cisco Router (IOS 15.2)

Hi, I'm trying to create Site-to-Site VPN between Cisco ASA 5505 and Cisco Router 3945.
I've tried create configuration with and without ASA wizard, but anyway it doesn't work.

Thanks for helping me again. I really appreciate.
I don't hve any NAT-exemptions in Cisco IOS Router. Transform-set I will change soon, but I've tried with tunnel mode and it didn't work.
Maybe NAT-exemptions is the issue. Can you advice me which exemptions should be in Cisco IOS Router?
Because on Cisco ASA I guess I have everything.

What's wrong? Verify and compare Cisco 2901 config after loading old config from Cisco 2801

Hi Cisco Community / Friends,
I am new to this site though I have cisco account for many years. I am a CCNA ,I passed my certification on January 2013 I seldom use and utilized my skills on networking becuase of my type of work. I am Project Eng'r working in a System integrator company . Anyway, I would like to ask assistance on the configurations of my Cisco router for this gov't projects.. Here's the situation.
We have a new project for the VSAT Comm'n of Coast Watch Station , The VSAT was installed 7 years ago. The VSAT was only used for a year by this Gov't agency because of subscription issue. Now, they wants to revive and use their VSAT facilities for the Coast watch monitoring. Now, some of this routers are working up to now and for some site are already defective so I need to replace the old 2801 router with a new equivalent model which is Cisco 2901. My plan was just to load the old config into the new Cisco 2901 router. However, after loading it to the new router, I am a little worried because I've got some errors received. I load the old config by copying the old files, edit it in notepad, and load the config using Secure CRT (terminal emulator). When I copy the old config of cisco 2801 to new router cisco 2901 , below are the command not recognized on Cisco 2901. What's wrong ? What are these commands for?
Appreciate your comments and help on this matter.. Thank You very much
Note: I Attached the original config from Cisco 2801 and the other file is the config after I load the config file to Cisco 2901.

Hi
From Cisco's website:
The Modem Management Interface (MMI) is software that enables auto-provisioning for the Cisco 827 routers. The MMI uses a fixed PVC to communicate with the Proxy Element (PE) residing on the digital subscriber line access multiplexer (DSLAM). Using MMI, the Cisco 827 router updates the running image and downloads the prescribed configuration using a configuration file or configuration values in a provisioning information database.
The customer premise equipment (CPE) can be automatically configured using the Cisco DSL CPE download, but it can be configured only with the image provisioning feature.
So because this is your device, you don't want to use MMI anyways.
And "priority-list" is QoS. Probably that QoS-command is old and removed, because now QoS is configured using class-maps and policy-maps.

New VLan can't talk to DHCP server

We have just created a new vlan (172.18.1.0/24 vlan 3) on our network and we are trying to use an exsisting DHCP server (192.168.0.1 vlan 8) But the clients on the 172.18.1.0 network can't connect to this DHCP server on vlan 8. My questions are.
1. Do we need to specify vlan 3 on the switchport that the DHCP server is plugged into?
2. Is there something @ L3 we need to enable to pass these DHCP server messages too across these vlans?
Has any used DHCP servers on different subnets?
Any info would be great.

You need to configure an IP helper on the appropriate VLAN interface(s). Routers, by default, will not forward broadcast packets. Since DHCP client messages use the destination IP address of 255.255.255.255 (all Nets Broadcast), DHCP clients will not be able to send requests to a DHCP server on a different subnet unless the DHCP/BootP Relay Agent is configured on the router. The DHCP/BootP Relay Agent will forward DHCP requests on behalf of a DHCP client to the DHCP server. The DHCP/BootP Relay Agent will append its own IP address to the source IP address of the DHCP frames going to the DHCP server. This allows the DHCP server to respond via unicast to the DHCP/BootP Relay Agent. The DHCP/BootP Relay Agent will also populate the Gateway IP address field with the IP address of the interface on which the DHCP message is received from the client. The DHCP server uses the Gateway ip address field to determine the subnet from which the DHCPDISCOVER, DHCPREQUEST, or DHCPINFORM message originates.

New Entry Point in Cisco Interaction Manager

I have created a new Entry Point in Cisco Interaction Manager for web chat. I used a new Queue and a new Script for the que script selector. I added a new ICM queue script for the chat, a new Dialed Number / Script Selector. When I test the new chat, the entry point works and shows the new entry point name in the CIM agent, but it still queues to the existing queue in ICM, not the new one. Anyone have any idea what I might have missed?
Thanks - Keith

Hey Lara, the emails are not getting queued because they are abnormally handled after success path of Queue to skill group.
please add a wait node, after success path of queue to skill group. set time in wait node to max time you want emails to stay in queue. may be after this you can use another queue or send some label back to CIM, which matches to non IPTA group on CIM.
the same is applicable for Chat as well.
coming to the point at the subsequent chat not routing to the same agent, this one depends on max concurrent task you configure in CIM for Chat queue.
there is config tab in each ICM integrated queue called "Concurrent task limit", this is the one deciding factor on how many concurrent task for each queue an agent can handle.
please try and let me know if that works.
regards
Chintan

Curious message during activation of snmp traps in cisco router 2800

I activated snmp traps in cisco router 2800 (I didn't specify a set of them, so all of them were activated). The thing is, when i configure "snmp-server enable traps", appears a message in the next line :
" %Cannot enable both sham-link state-change interface traps.
%New sham link interface trap not enabled "
Anyway, traps are activated and are completely functional.
I would like to know, why this message appears... and also what is the difference between informs and traps, because I can activate both of the in a router to be sent to the network admin pc.
Thanks in advance.

Hi Marcelo,
the snmp-server enable traps command enables just all types of traps that the IOS version supports.
The message apperes because of this two, which are mutually exclusive:
R1(config)#snmp-server enable traps ospf cisco-specific state-change shamlink interfaceR1(config)#snmp-server enable traps ospf cisco-specific state-change shamlink interface-old% Cannot enable both sham-link state-change interface traps.% Deprecated sham link interface trap not enabled.
It's recommended to only enable the traps you really need.
Informs were introduced with SNMPv2, and they have the same format and purpose as traps.
The main difference is that traps are send in a hit-or-miss fashion whereas informs expect an acknowledge and will be re-send if unacknowledged.
Hope that helps
Rolf
