CiscoWorks and 10 Gigabit Switch Blades

Greetings!
Does CiscoWorks support 10 gigabit blades for IBM blade centers? We have two of these and CiscoWorks catagorizes them as unknown devices.
Thanks,
barb

Hi Brobson,
Here is the Device Supported List for LMS 3.2
http://www.cisco.com/en/US/docs/net_mgmt/ciscoworks_lan_management_solution/3.2/device_support/table/lms32sdt.html
If you have any other version of LMS, kindly let me know and I will share the Device suported list accordingly. Usually for Cisco devices we always look for SysObejctID of the device to see if the device is actually suported in CiscoWorks.
Thanks

A 10/100 Router and a gigabit switch...will they get along?

I am setting up my business network between multiple computers. I need gigabit speeds for large file transfers (video, audio, images), but I also need internet connectivity. I was planning on using a simple 10/100 4 port broadband router and a Netgear Prosafe 24 port 10/100/1000 gigabit switch. If I connect the router to the switch, will my network's performance decrease since the router is responsible for assigning ip addresses, or will the switch's gigabit speeds still work within my network (since switches operate using MAC addresses)? Can anyone help me on this one? Thank you!
P.S. --It's also between Mac and Window systems
Powerbook G4 17" Mac OS X (10.4.7)

If the devices plugged into the gig-switch have gigabit ethernet ports, then you will see a speed advantage over 100mbps performance. I have a similar setup, with a 4-port linksys router that is 10/100 and an 8-port linksys gig-switch connected to it. I connect my printer and VOIP adapter directly to the router, since they aren't gig anyway, and connect my other devices to the gigabit switch.

New 150/65 only at 94 Download AND Won't Work with Gigabit Switch

I just had this installed today, converting up from the 35/35, and ran into these two problems:
1. The 150 download is only resulting in a 94.87 Mpbs. The installer originally said it must be my PC NIC card, but I do have a GB card, so there's does not appear to be legitimate reason for the shortfall there. I tried to change the link speed and duplex from "auto negotation" to "1 Gbps Full Duplex," but then my computer no longer even could connect.
2. The second issue is that I have always run my connection through a D-Link DGS-2208 Gigabit Switch because I have multiple wired ethernet computers in my office. The installer wanted to test the connection speed directly through my computer (see above) and ran into problems, so I never even tried to revert to my original setup with the switch until he left. However, when I did the Gigabit switch does not even recognize any activity when I plug the source ethernet cord into the switch. It does recognize the connection to the PC and the port is lit, but no lights from connection to the wall.
Any thoughts on what the problems could be? I've included the "additional details" from the Fios Speed test at the standard site (can't get any details from the high speed version):

If your computer can't negotiate a 1Gbps connection, then that is what is limiting you to 94Mbps, which is about right for a "100Mbps" port.
There could be several reasons for this.
A bad NIC
A bad port on the switch
IMO, the most likely cause is a bad cable. 1Gbps requires all 4 pairs in the cable be connected. If only 2 of the 4 pairs are connected correctly, you will get a 100Mbps connect, but will not be able to connect at 1Gbps. Try replacing the cable with one known to work at 1Gbps.

Airport wifi problems with uverse and gigabit switch resolved

I think there is a bug in airport firmware 7.6 with how spanning tree works in addition to problems with the Uverse router. Having an Airport with a uverse 2wire 3801 and gigabit switch will not work. Putting the extreme in NAT mode with DMZ plus behind the uverse resolved the problem.
Network configuration:
Uverse 2wire 3801 router
    3801 provides prioritization for upstream traffic so skype and VoIP work better when doing a lot of stuff on Internet
Airport extreme firmware 7.6
two airport express 802.11n hardwired to extreme. Set up in bridge mode. All access points have same SSID "create a network" to enable roaming. Ignore anything to do with extending a network. firmware 7.6
two gigabit switches
    Netgear GS608 - 8 port gigabit switch
    Trendnet TEG-S80g - 8 port gigabit switch
    100BT 5 port switch - did not figure into problem
Three Uverse set top boxes wired on Ethernet. They have to be wire directly to the 2wire box to work correctly. See: http://forums.att.com/t5/Features-and-How-To/At-amp-t-U-Verse-modem-setup-Airpor t-Extreme/td-p/2300785
However, you need to be careful to place your own PCs and other internet devices on the network created by your gear (airport extreme in your case), but keep AT&T's set top boxes for the IPTV services IN FRONT of your own router - so they remain on AT&T's provided network.
So it would work like this ...
Network 1: 2wire RG (4 lan ports) -> Any Set tops, and to the WAN port on your AirportExtreme
Network 2: Airport Extreme LAN ports -> to any computers or internet devices (but not AT&T set top boxes).
The RG prioritizes the traffic for your Uverse Voice and your Uverse TV ahead of internet data traffic, as it rationalizes data heading out of your home. If you place your own equipment in that equation (like putting AT&T set top boxes behind your Airport Extreme) the performance and function of your AT&T set top boxes could really flake out on you.
Symptom:
    Everything would be working fine, then intermittently all my wifi access points would stop working. ~6,000 ms latency, dropped packets. Ethernet worked fine. Here is an example of my macbook pinging the extreme when associated with the extreme over wifi with a strong signal.

64 bytes from 192.168.1.64: icmp_seq=36 ttl=255 time=39.828 ms
Root cause:
    It looks like the 2wire 2801 router has a problem with spanning tree when interoperating with gigabit switches and airports. There is interplay with the airport.
I did not have this problem until the 7.6 airport firmware. I had been using the Netgear hub for about a year with the extreme in bridge mode. I added the Trendnet hub and upgraded airport firmware at the same time which made fault isolation difficult.
Problem recreation:
Set up airport expresses hard wired to extreme
Connect gigabit switch anywhere to network
Everything OK
Dettach one computer from wifi then reattach, then all wifi stops working. It takes a few seconds for the problem to propagate.
Ethernet still works fine
Problem Resolution:
Connect to 2wire with ethernet
Set 2wire route to have subnet as 192.168.2.x
Set extreme in NAT mode behind 2wire. It will complain about double NAT. Override the warning. Set the subnet to 192.168.1.x so you don't have to change any static IP addresses. Note that 2wire uses 192.168.1.254 as default route whereas airport uses 192.168.1.1.
I set DHCP to start at .10 to leave the lower addresses for assigning static IP addresses to computers I want to expose outside the firewall.
Go into firewall settings. Select airport extreme. Select the bottom setting which is "DMZ Plus". When you go into the airport extreme settings, you will now see that it has the uverse public IP address on its WAN port. NAT port mappings work fine on the extreme behind the 2wire router.

Keeping this very short here is a summary of the actual problem and solution to allow your Apple Airport Extreme to run in Bridge mode on the same subnet as your uVerse settop boxes (if your Layer 2 switch is configurable).
Devices: Uverse, Cisco SG300, and Airport Extreme
uVerse uses Multicast to broadcast video streams between the uVerse network to the settop box, and from settop box to settop box.
X number of Multicast Groups are created based on X number of settop boxes you have. You can see the multicast definitions by logging into the webinterface of the iNid. Each settop box is a member and can choose to display a broadcasted TV stream or not.
Multicast membership is setup by the use of ICMP messages for IPv4 (MLD for IPv6). Each of the settop boxes become members of each others multicast group by reporting up to the iNid (MultiCast Proxy).
In an ideal world a layer 2 switch will track these memberships and only forward a broadcast packet to the ports on the switch to which the settop boxes are connected to. The switch would do these via snooping on the ICMP packets. Most switches by default do not do this by default and simply forward the broadcast packett out every one of it's switch ports.
Here in lies the problem. Problem is that the Apple AES doesn’t do ICMP snooping / filtering and floods the wireless network with these broadcast streams.
In order to fix this you must turn on ICMP snooping and filtering on the switch (or buy a switch that does this). I have a Cisco SG300 and list out the configuration below.
Other notes:
Ensure that all Media renderers (settop boxes) and servers are wired directly off the switch and not attached to any of the Airport Express ports. This way no media transverses the Airport (only control point traffic goes through the WiFi - which is fine). Obviously if the IGMP snooping switch sees any client requesting Multicast streaming traffic on the same port as the WAP, it will add that Multicast address to the forwarding table for that port, and then, yes it could get flooded.
Remember, you need to allow some Multicast traffic through your WAP to allow UPnP discovery to work (assuming that you will be using Wireless control points.)
Read the Multicast chapter in the SG 300 switch Admin Guide as it explains things very well.
Setting up multicast on the SG300s using the WebUI:
1. Multicast/Properties/
Tick enable Bridge Multicast Filtering Status for VLAN 1, and
set the Forwarding Method to IP Group Address for both IPv4 & IPv6.
2. Multicast/ IGMP snooping/
Tick enable IGMP snooping status then select and edit the entry and ensure that IGMP querier status is ticked.
It's essential for IGMP snooping to work that there must be at least one active IGMP querier on the network - if more than one is enabled, they will carry out an "election" to decide which one should be active (normally the one with the lowest IP address.)
3. Multicast Router Port
Set whichever port that is connected to the uVerse iNid to Status which means that it the uVerse router connected to this port is the Multicast Router
4. Multicast/ Unregistered Multicast
set all ports to Filtering. (The default is Forwarding.)
There are a lot of other variables within all the above - the defaults are OK, you should probably leave them alone!
In the config file you would then expect to see the above appearing as something like this:
ip igmp snooping
ip igmp snooping vlan 1
ip igmp snooping vlan 1 immediate-leave
interface vlan 1
bridge multicast mode ipv4-group
bridge multicast ipv6 mode ip-group
interface range gi1-10
bridge multicast unregistered filtering
ip igmp snooping vlan 1 querier
ip igmp snooping vlan 1 querier address <IP-Addr>

Time capsule and gigabit switch

I am planning to expand my wired home network to be able to connect my xbox, blu-ray, tv, and other devices. I am looking at getting a gigabit switch. Any advice on what works best with TC? what's a 'smart switch'? do I need POE? we mainly have MB and MBP in the house.

Since this appears to be a home networking application, all you need is a simple unmanaged powered switch. The GS608 would do all you need and more, likely exceeding the quality of the switch built into the Time Capsule.
If you want to move up into business class switch, but drop down in product appearance, then go with the GS108.
The other switches appear to be managed solutions which require software applications and other associated specialized hardware. Power over Ethernet (PoE) would be of no use unless you happened to already have other PoE products in your network...and no AC outlet for the switch.

High CPU Usage / Dropped Packets - Switch Blade WS-CBS3120X-S

Hi all,
I have a couple of Switches Blade 3120, working as active-standby model (HSRP) on a new site deployment. There are other 20 sites more or less, working on the same model, without issues. But in this one, we are seeing a high cpu usage. The traffic going through the platform is 600Mbps (on peaks), and in this case we have 40% of CPU usage. Traffic should be close to 3 Gbps. When we tried to send the whole traffic through the platform, active switch began to drop packets on the majority of interfaces.
When we analyze the CPU usage, there is a special process called "HL3U bkgrd proce" always have the most CPU use, but we do not know what concerns. We do not know if it is caused because there are PBRs configured. It should not matter. How I mentioned, there are other sites working fine and have had always the same PBR number.
Could you guys help us?. Any idea what is causing the high usage?. Is there a special debug we could to perform to diagnose the issue?. Also, we have seen a high interrupt CPU usage (9% in this case).
Find attached the whole diagnosis outputs.
Thanks for your assistance guys.
Cheers,
Juan Pablo

AirPort Extreme 802.11n as a wireless router and local network switch?

Good afternoon,
I'm curious if its possible to have the APE in wireless network mode and connect systems via hard line as well?
I have an AirPort Extreme 802.11n set to "Create a Wireless Network" mode that is attached directly to a cable modem for internet connectevity. My issue is that while all wireless devices (several iPods, two iPhones and three laptop computers) connect to the APE without issue (and have internet access), when I try to plug in a Windows 7 desktop computer via one of the ethernet jacks, Windows is unable to connect and shows the network as "unidentified," spitting back a private IP address as opposed to a local LAN (this behavior repeats for an Ubuntu Linux box as well).
Not sure if the APE is misconfigured, this is a Windows 7 issue or if its improper use on my part (though this also precludes me from connecting a gigabit switch to the APE).
Thank you,
Nathan

Properly configured, the AirPort should provide both wired and wireless network client with Internet access.
At this point, I would recommend that you do the following as a minimum:
Power-down the modem, AirPort base station, and computer(s).
Power-up the modem; wait at least 10-15 minutes to allow it adequate time to initialize.
Power-up the AirPort base station; wait at least 5-10 minutes. Note: The AirPort's status light may continue to flash amber after it has intialized. That is because, there may be some additional configuration items necessary, like setting up wireless security, before the overall setup is completed to get a green status.
Power-up your computer(s).
If the above steps do not solve the problem, start over with step 1 above, but then perform the next steps between steps 1 & 2. above.
Disconnect the AirPort base station from the Internet broadband modem.
While all of the devices are powered-down, perform a "factory default" reset on the base station. This will get it back to its "out-of-the-box" configuration and make setting it up much easier, especially if you use the "Assist me" process within the AirPort Utility. (ref: Resetting an AirPort Base Station or Time Capsule)
After the base station resets, go ahead and power it back down.
Reconnect the AirPort base station to the Internet broadband modem. For the Extreme and Time Capsule, be sure to connect the cable to the base station's WAN (circle-of-dots) port.
Continue with step 2 in the first set of steps.
In this basic configuration, the AirPort base station will broadcast an unsecured wireless network with a Network Name (SSID) of Apple Network NNNNNN. Network clients, connected to the base station either by wire or wireless, should now be able to access the Internet through the ISP's modem. Once Internet connectivity has been verified, you can use the AirPort Utility to configure the base station for wireless security and any other desired options. Please post back your results.

G5 imac wont connect to gigabit switch at 1000

Hi,
I've got a G5 imac that wont connect to my gigabit switch at 1000. It looks like it connects at that speed for a few seconds then it drops to 100. I have a new Macbook pro that can easily connect at 1000 using that exact same cable.
Has anyone heard of any gigabit issues with G5 imacs?
Thanks,
Scott

I am now pretty sure it is the imac ethernet port. Connected the imac and mini together and eventually it set itself to 100Mbs.
Now trying to decide if it is worth getting fixed or just dealing with it only connecting at 100Mbs.
Thanks
Jason

Adding Two Gigabit Switches to Airport Extreme

I want to add an 8-port D-Link gigabit switch to my brand new Airport Extreme to network my Mac Pro, my iMac and two printers in the office. The MacBook Pro would run wirelessly. Then, I want to add a 5-port switch 100-feet away (and down another floor) to directly wire the Apple TV, the DSS tuner, the blu-ray player and maybe use my older non-n Airport Extreme to radiate in that far away room also. Sound like a plan to you wizards? :--) Or am I nuts. Using gigbit cables.

Nope just get a small ethernet to go from one of the 4 hookups on the AE to go to the switch.

Aironet 1140 series units won't connect to a gigabit switch

I just installed 2 new units and neither will connect to a new HP gigabit switch - no link light, other devices can connect to the switch OK. Their gigabit ethernet settings are set to auto for duplex and speed. I also tried forcing one of them to full duplex and 1000 Mbps which didn't work either. They're both powered by POE injectors. If I connect them to a 10/100 switch they work fine.
Am I missing something?

Leo,
Thanks for the reply, sorry I'm late getting back to this, I was lucky enough to have a long weekend off.
I'm no cabling expert, that's why I hired somebody else to do it. But I have a question: should standard cat 5 cable work?
If so, I disconnect the WAP from the cabling that was installed and hooked it up with cat 5 patch cables that I confirmed to be work OK by using them to connect the gigabit switch to a laptop. When I used the same patch cables on the WAP I still got a failure to connect to the same switch. So unless it's not standard cat 5 that I should be using it doesn't appear that cabling is my problem.

Replacing high density port switch/blade strategy

Hello,
I'm looking for strategies in replacing 48 port blades/switches while minimizing downtime. Our management wants to know how long it would take to replace a switch and re-cable it. So I'm trying to find some best practices on replacing switches/blades and how to maintain cable to port integrity when moving between switches/blades. The only thing I've really found comes from data center infrastructure, where they stress the importance of labelling cables.
I was wondering if anyone else had other strategies they use when replacing high density port switches/blades
Thanks in advance

Label, Label, Label.
I can't stress it enough, especially if you're trying to do a "mirror" replacement and have everything working exactly the same as it was before. Don't rely on memory, don't rely on out-of-date documentation - label every cable
If you're talking physical switches, then configure them FIRST to match your existing configuration (VLAN's, SVI's, Trunks etc etc), then label *every* cable plugged into your existing switch, pull the old one out, mount the new one, then put your cables back into place based on the labels.
If you're talking blades, the process is about the same except you *shouldn't* have to worry about configuring first - if you're doing a slot-for-slot replacement, the port designations should remain the same, and your existing config should just take effect on reboot.
If it's an additional module in an empty slot, just plug the module in, duplicate the configuration from the existing module, and move your cables one-by-one to matching ports on the new blade.
Cheers
Trap for new players in blade/modular environments - make DAMN sure the IOS version you're running actually supports the module you're installing - or you're going to end up in a mess!

How do I reuse an E3000 as a wired gigabit switch?

Hi, I'm trying to setup my old e3000 as a wired only unmanaged gigabit switch, I have disabled wifi broadcast, is
there anything else I have to do?.
Do I need to disable NAT and enable RIP? Thanks in advance
Solved!
Go to Solution.

You will need to disable its DHCP server (this basically disables NAT) and adjust its Local/ Router IP address to fit your network. To have the E3000 function as a wired switch, you have to connect it to the main router via its LAN port. For more information, refer to the article below. Follow the instructions on LAN- LAN setup.

Adding a Gigabit switch to HH2 - any point?

I currently run my home network though a 10/100 switch connected to my HH2. My son plays on-line games and watches 'on demand' TV programmes. Occasionally there's some 'stuttering' on sound and picture.
Would there be any improvement if I swapped out my 10/100 switch for a Gigabit one, or would this only affect 'internal', home network file swapping/sharing?
I've tried asking BT Technical what the speed of the ethernet ports are on the HH2...

I think you've guessed the answer already... it won't make online access any better, the bottleneck will be your broadband connection. The gigabit switches (and NICs for that matter) tend to use more power and run hotter in my experience, so I wouldn't recommend the switch unless you have a definite requirement for one.

My ethenet LAN slows down when I use a (supposedly) faster gigabit switch.

I am using the latest version Airport router. It is providing our home wireless network, which is working fine. I also have a home ethernet LAN. The Airport is connected to an old, cheap, no-name 100Mb switch. I decided to try a Netgear GS608v3 gigabit switch to see if it would allow faster ethernet LAN (of course I understand that it has no effect whatsoever on the WiFi network). The indicator light for the port where the cable from the Airport plugs into the swich glows yellow, indicating only Mb speed. The indicator lights for the other ports running cables to my wired devices all glow green, indicating a gigabit connection.
When using my web browser, I was expecting that I would not really be able to see any differences, but to my surprise the new Netgear gigabit switch was associated with dramatically SLOWER web page load times. And I mean s-l-o-w. Something is wrong here. It should be as fast or faster. And why is the input from the Airport router indicating only 100mb speed?

the problem is with the Netgear switch for SURE. you can not have packet loss on internal network.
going further:
You can troubleshoot this problem. but will take a while.
using the finder, go to network utility and select your ethernet connection,
on right side you will see Transfer statistics
if send errors or recv errors or collision are being incremented you have a problem between your mac and the switch port, (you can have problem from the switch to the router too).
In order to resolve this problem:
system preference
network
selecet ethernet
select last tab (Ethernet)
configure: manually
set speed to 100baseTX
duplex to full duplex, flow-control.
ok
apply
repeat the ping test
you can reach airport page and check for errors on lan ports.
more one tip: you need use CAT5e cables, read the cable and post the results

Connecting two linksys gigabit switches

Hi,
I just bought a slm2024 (24 port managed Gigbabit switch) to replace an older 100Mbit switch. The old switch had PCs and other switches connected to it. The other switches are EG005W ver. 3. (linksys workgroup 5 port gigabit switches)
With the new slm2024 switch, the PCs have no problems connecting. The problem is the EG005W switches. The port on the slm2024 which connects both switches is dark (the LED is dark - no lights at all). Any thoughts on what is the problem? Do I need to configure something special on the slm2024?
I do have an older 100Mbit switch and if I connect it to the new slm2024 switch, the lights are on and traffic is flowing. It is just the EG005W that does not seem to like being plugged in the gigabit switch. It used to work when plugged in the older 100Mbit switch.
Oh and if I try to plug in two EG005W together, I get the same problem. PCs connected to the 2nd switch cannot communicate out either.
I understand that in the past cross-over cables where needed to connect switches but I thought that new switches no longer require this (even my old 100Mbit switch did not require this for the EG005W to work through it).
Any thoughts on how to fix or debug this?
Thanks for any suggestions.

there shouldn't be any configuration needed on the ports of the SLM2024 because they are already "smart ports"
this could be a possible problem between these 2 devices -- have heard of similar problem before bet. a switch and hub but i have forgotten their model numbers -- you would think that since they came from the same manufacturer you will have an easier set-up but sometimes that's just not the case
