why cat2960 tags native vlan 1 on 802.1q trunks ?
I know that 802.1q does not tag native vlan.
Is there a way to UNtag the native vlan on cat2960 ?
Yes this command is not supported on 2960 as of now because 2960 does not support the feature of tagging native vlan. This command is available on switches like 3560 , 3750 and above.
At the moment native vlan is ALWAYS UNTAGGED on 2960 switch. But because the output format structure of show commands are common for most of the IOS platform switches and that is the reason we see this output in "sh interface switchport" command but that is a bogus information and should be ignored.
