HELP! Configure cisco fast ethernet card

589 Views
Last Modified: 2012-06-21
I have a 2600 router that I need to take out the ethernet card and add and fast ethernet card.  I am running cisco ISO my question is what commands to I need to run to make the fast ethernet card work.  Basically can someone walk me through configuring the fast ethernet card and the proper steps in doing so.

Thanks

The only thing you'll need to do is reference it as "fastethernet" instead of "ethernet".

You will also have the option of specifying the speed. Or you could let it auto negotiate the speed and duplex which is the default.

 

Commented:
Because IOS will renumber and rename interface, all the settings for ethernet interface will be lost including IP, so if you have any access lists, policies or routing maps on the interface you need to save it and reapply to the new FastEthernet interface. It's recommended to force speed and duplex settings on the router and switch interfaces if possible and not count on aut-negotiation.

old config
Ethernet0/0
  ip address <IP><MASK>
  ip access-group <name> in
  service-policy <name> out
  .....

new
FastEtherenet 0/0
[Copy and paste all the settings]

What model 2600 do you have and what version of IOS are you running? If you have a non XM 2600 then it does not support the FE network modules. 2600XM models came with built in FE interfaces.

Unless you have a 2691XM I do not think it suports the FE network module, Please provide the additional information detailing the model and IOS version to know for sure.

What is the part number for your FE module? The base 2600 does not support any of the FE Network Modules.

Thanks, tvman. I looked at the document referenced and the chart said N/A for 2600, but I think it doesn't mean it is not supported, just says that there is no limit since the limit is physical one of only one NM slot anyway...

The documnet I have does not list the 2610 as compatible with the nm-1fe-tx. Furthermore, even if it recognized it (as yours does) it will not work at full capacity, the 2610 is only capable of 7.68Mbps throughput. So best case this module will work approximately like the ethernet module you had installed.

Looking at your "show diag" output obviously your system recognizes this network module at the hardware level. Do you see the interface when you issue a "show ip interface brief" from IOS? If so you configure it
like any other interface. If you do not see it, it may be because it is incompatible

router#config t
router(config)# interface fX
router(config-int)#ip address x.x.x.x y.y.y.y
router(config-int)#no shut
router(config-int)#exit

What problems are you having specifically?

This router has almost 2 years uptime. I don't have any problems. Using FastEthernet module allows me to use 100/full mode.
It is not working at full capacity because router connected over T1 to the rest of the network. The original question was how to configure FastEthernet on NM module and there was a statement that it's not possible, so here is a proof from real life.

Can you see the interface via the "show ip interface brief" command, if so , try to configure it like I detailed in my previous post. If it is visible there then you should be able to configure it.

router#config t
router(config)# interface fX
router(config-int)#ip address x.x.x.x y.y.y.y
router(config-int)#no shut
router(config-int)#exit

I checked and it looks like I have a 2650 router and it should support the FastEthernet card.  So if I just copy the config and input fastethernet where it says ethernet I should be good?
