Q-in-Q with vlan remapping limitation

[James Lasky]

Hi

I understood that there is a limitation on ME 6524 regarding q-in-q vlan mapping on a single interface at 8 mapping maximum, in Cisco documentation was written ISL and not 802.1q...

Does anybody know if there is a fix ?

Or how can I bypass this limitation ?

Example of the Cisco 6500ME with vlan remapping:

QinQ trunk 802.1q with a MetroEthernet provider

interface GigabitEthernet1/31
description Provider MetroEthernet connection
switchport
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 120,180,260,309,340,370,864,935,1035
switchport mode trunk
switchport vlan mapping enable
switchport vlan mapping 864 309   <-------------- vlan remapping

switchport vlan mapping 935 120   <-------------- vlan remapping

etc

etc
switchport vlan mapping 370 180   <-------------- vlan remapping up to maximum 8
mtu 9216
no ip address

Tks

HI,

It's a hardware limitation so there is nothing you can do about it. Also please be aware that on the following platforms, vlan map is not supported on ports 1-24:

ME6524GS-8S
ME6524GT-8S
