show interfaces trunk cmd missing

May 02, 2009 5 Replies

I have a couple of old switches, 2900 and 3500 series (IOS 12.0(5).WC5 and 12.0(5)WC7)



Configuring trunking on these is awkward.



The normal vtp commands are not there, for example to configure the domain, server/client, etc, I have to type "vlan database" first, then run the vtp commands.



Fortunately I was able to get trunking to work, but was wondering...



Is there is an equiv command to "show interfaces trunk" on these older devices/or IOS?



"show interfaces trunk" is not one of the commands, as are the other vtp commands.



Is my IOS too old or do I need different switches?



Thanks in advance:)


Google probably would have saved you on this one. One of these should always work:

(privileged) show interface type mod/port switchport

-OR-

show interfaces trunk

-OR-

show interface [mod] [interface_id] trunk

The first two aren't available on all switches as you have found out.

show interface status is also good if that is available.

Well...seems that

show int status sort of helps, but I was looking for info similar to:

----not from my switch---- SW1# show interfaces trunk

Port Mode Encap Status Native vlan Gi0/1 desirable 802.1q trunking

1

Port Vlans allowed on trunk Gi0/1 1-4094

Port Vlans allowed and active in management domain Gi0/1 1,3-5, 49-50

Port Vlans in spanning tree forwarding state and not pruned Gi0/1 3-5,49-50

------end of cut------------------ Unfortunately these commands

show interface [mod] [interface_id] trunk or show interfaces trunk

do not work on my switches...so I was looking for something that would show similar output:(

Thanks much anyway Trendkill...appreciate the quick response.

The command on those older switches

show int faste 0/24 switchport

Gives you much the same info, just in different format.

These switches are old. Things changed for the next generation much easier and better.

=A0 =A0 =A0Status

Oh well...I thought maybe there would be an obscure undocumented command...thanks:)
