I am reviewing a config file of a 6500-SW and it shows that there are 5 VLANS configued. When I did a show cdp neighbor details, it only showed the default vlan (VLAN1) and no physical links to any other devices. This switch is offsite and I just got the assignment to analyze the network toplogy and document it. The question is, what command(s) can I used to see what the phyiscal links on this switch is/are?
Your help is very much appreciated,

show ip interface brief
you can also do add "| include up" to only see the active links.

Thanks for the prompt response.
I had used the sho ip interface brief command and all the VLANs showed up under the interfaces column but none of the physical interfaces showed up and that's confusing me. I only see all the VLANs when I do sho interfaces, show ip intefaces brief but none of the physical interfaces are displayed.

Thanks for the reply but those commands didn't work. I can do a show module and received the module name but i the other command wasn't valid (sho int status module #)

You can also just try a "show run" to see the physical interfaces and "show vlan" to see the interface to vlan mappings.

I have tried all of those commands and under the interfaces, the VLANs would be displayed but not the physical interfaces. This is a 6500 switch by the way!
Thanks,

Hi
That doesn't look like the full output of a "sh module". Have you copied exactly what was on the screen.
It looks from the output that you only have a CSM (which is a loadbalancer) in the chassis. If this is the case then that is why you are not seeing any physical interfaces. But you should at least see physcial interfaces for the supervisor module.
A "sh module" from one of my switches looks like this
SZ-JFH-F00-DTE1#sh mod

Are you running in hybrid or native mode on your 6500 ?

Yes, I copied all the output off of the screen.
I am not sure if the switch was configured in hybrid or native mode! How can I find out?

Hi
Well "show module" should tell you :).
This is confusing because when you do a "sh module" you should at least get the supervisor in the output as well as the CSM.
When you log into the switch can you post the output of a "sh version".
Can you also post the output of "sh cdp neigh" please.
Jon
01-16-2008 12:11 PM
Sorry i didn't pay enough attention to the output.
Don't type in "sh module ?"
Just type in "sh module" and then hit return and then paste the output.
Jon

It returns a "% incomplete Command" message after i type sho module

Hi
Okay, it's been a while since i used a 6500 in hybrid mode but i think this is what you have. You need to get onto the layer 2 switch part of the 6500 as i suspect you are on the MSFC.
Can you post the output of a "sh cdp neigh".
