Well that certainly is interesting seeing that it is part of the 4500 series switch command and the 4948's use the 4500 code . What code version is that running ? Looks like it has been there since 12.1.13EW if your code is older than that then it won't show up .


show vlan counters


To display the software-cached counter values, use the show vlan counters command.


show vlan [id vlanid] counters

Syntax Description


id vlanid


(Optional) Displays the software-cached counter values for a specific VLAN.


Defaults


This command has no default settings.

Command Modes


Privileged EXEC

Command History

Modification

Support for this command was introduced on the Catalyst 4500 series switches.


Usage Guidelines


If you enter the show vlan counters command without specifying the VLAN ID, the software-cached counter values for all VLANs are displayed.

Examples


This example shows how to display the software-cached counter values for a specific VLAN:


Switch# show vlan counters

I know that it uses 4500 IOS but seems like Cisco decided that such a device won't need any hardware counters for vlans (I doubt that software counters for gig 48ports is good idea).


Here is the "show ver" dump:
