native vlan doesn't have a tag added to it by default. Must add this if you want to tag the native vlan on trunks with dot1q encapsulation. There is no equivalent command with ISL because ISL encapsulates all VLAN's by default

What does it do? JT On Sat, Apr 16, 2011 at 11:01 AM, Kingsley Charles <[email protected]> wrote: Hi all I tried to configure inline vlan pair on a sensor pairing vlan 1 and 23. I enabled 2004 and 2000 signatures.Traffic from 23 was coming in but not from vlan 1 i.e., it was unidirectional. Since vlan 1 is the native vlan, it should have been sent untagged and hence the sensor didn't swap it. Hence I tried configuring vlan dot1q tag native and changing the native vlan to some other vlan other than 1, still I faced the same issue. What could be the problem?
