They aren't overly expensive and would definitely be recommended over a setup involving fudging around with floor/access switching products that weren't really designed to do this sort of thing..<span class="HOEnZb"><font color="#888888"><br>

That's pretty close to my scenario.<br>
<br>
For the purposes of clarity and using a Cisco example let's say I get handed off double tagged VLANs 2, 4 and 6 which each encapsulate two VLANs each e.g. VLANs 21,22,41,41,61 and 62. How can I get to a scenario where I can strip the outer VLAN ID's and trunk the inner VLAN's to my next device e.g:<br>
<br>
interface GigabitEthernet1/0/43<br>
description egress interface<br>
switchport trunk encapsulation dot1q<br>
switchport trunk allowed vlan 21,22,41,41,61,62<br>
switchport mode trunk<br>
load-interval 30<br>
end<br>
<br>
