You shouldn't need too many with only 8 ports . Early versions of the 2940 did not support many. Newer versions of IOS supported more.

True. I guess I was just referring to how to find out the max vlan supported.

Hi Glen,

Thanks for your valulable support. show version output is attached herewith. Please be advise with the newer IOS.

Thanks in Advance---Jeet

Hi Glen...Waiting for your update!!!

A 3750 switch will support up to 1005 VLANs as shown by sh vlan br and sh vtp status. Both output show the max VLANs supported locally.

Hi..but i am using 2940 switch..is it applicable on 2940 also?

sh vlan br

sh vtp stat
