Probably an easy switch config question.

I have a Cisco 4900M switch. It has two of the 8 port RJ-45 TenGig Ethernet cards in it. Was initially set up by a consultant.

I have used the first 8 ports on the first card. I just went to the 9th server, and now when I plug the ethernet cable into any of the 8 ports on the second card I get no link, nothing. The interface shows down, line protocol down (notconnect). A "show vlan" shows all the ports from BOTH cards are in Vlan1.

I did a "show tech support", and found some differences between the ports that work, and the ones that don't. Here are examples:

On a port that does not work the VlanID shows 4095. The STP state shows vlan 4095 (blocked)

On a port that does work the VlanID shows 1. The STP state shows vlan1 (forwarding).

So I think I found the issue, just don't know how to correct it.

Looking at what you have here, might be a bad module, maybe try re-seating it. If it does not work I presume, get Cisco TAC involved.

You need to assign the port you want to use to a particular vlan for it to work.

for example:

conf t

int gi0/9

switchport mode access

switchport access vlan 1

spanning-tree portfast

Hope that helps.

If the port is down and line protocol down (notconnect), then you have a layer-1 issue.  Check your cable and make sure it is good.

Thanks for the replies.

Cable is OK, lights right up when unplugged from the 4900 port and put into a port on a 3750E.

Tried those commands. That did not work either. Nothing appears to have changed with the config, still showing 4095 and blocked.

There are some error messages in the tech-support: linecard-4-ethphyseuevent: te3/3 detected a soft error event--recovery process completed. See multiples of this.

Probably an easy switch config question.

can you post the following:

sh run int xxx {one for the interface that works and one for interface that does not work}

sh int xxx capabilities {one for the interface that works and one for interface that does not work}

sh vlan

Boy is that ugly. Cut and paste don't work so well.

Cisco tech support agrees. They are sending a new card. Thanks!
