Hi gogomilky,


What is the output of show ver on this switch, I think it may be the IOS version that is the problem, not your command.

As mentioned by Luckymike33,

As mentioned by Luckymike33, it would be helpful to know which IOS version your switch is running.

Gogomilky,Allow me to correct


Allow me to correct you. That's not the IOS version.

When you do a "show version", look for the line where it says: "System image file is "flash:/...."

Wass, You are wrong, SW IOS


You are wrong, SW IOS version is 12.2 and *.bin extension is only file which hold IOS. The full name of flash is: flash:/c2960-lanbase-mz.122-25.FX.bin

From full path of bin file how can you conclude on which the version of IOS works ???

hi,i don't think it's


i don't think it's supported on the 2960. although it says 12.2(25)FX and later supports PVLAN edge but i believe that might be an inconsistency on some cisco docs.

i also don't see it on cisco's feature navigator ( if you click on 'Private VLAN - Edge' it shows you 1800 platform (not sure why). see attached.

still can't do copy/paste thing using the new CSC format. not sure why they've removed it.

Gogomilky,Maybe I was wrong


Maybe I was wrong as you said :) But what I know is, in order to show the IOS version being used, a quick way is to do a "show version" and look for the full name of the IOS

Also I had PT 6.0 and pipe "|" don't function on either IOS version 12.XXXX and 15.XXXXXX (Version 15.1(4)M5)
