Vlan translation topology mode
Configuration Item Configuration Explanation
VLAN-translation Port1 of PE1 and PE2.
Trunk port Port1 and Port10 of PE1 and PE2.
Configuration procedure is as follows:
PE1, PE2:
switch(Config)#interface ethernet 1/1
switch(Config-Ethernet1/1)#switchport mode trunk
switch(Config-Ethernet1/1)# vlan-translation enable
switch(Config-Ethernet1/1)# vlan-translation 20 to 3 in
switch(Config-Ethernet1/1)# vlan-translation 3 to 20 out
switch(Config-Ethernet1/1)# exit
switch(Config)#interface ethernet 1/10
switch(Config-Ethernet1/10)#switchport mode trunk
switch(Config-Ethernet1/10)#exit
switch(Config)#
Note: this switch only supports the in direction.
16.4.4 VLAN-translation Troubleshooting
Normally the VLAN-translation is applied on trunk ports.
Normally before using the VLAN-translation, the dot1q-tunnel function needs to be enabled
first, to adapt double tag data packet processes VLAN-translation.
QoS only matches vlan-id that the packet is translated when vlan-translation and QoS be
configured at the same time.
