DXS-3600 Series Layer 3 Managed 10Gigabit Ethernet Switch CLI Reference Guide
If the RESULTANT-VLAN parameter is specified in this command, the rule performs VLAN translation.
Once the VLAN tag of the incoming packet matches the specified original VLAN, the specified S-VLAN
replaces original VLAN. The VLAN translation is one-to-one mapping, i.e. you cannot configure multiple
original VLANs map to single S-VLAN. The VLAN translation can be configured on both 802.1q tunnel or
trunk port.
Optional, configure a 2:1 VLAN translation rule by specifying the ORIGINAL-INNER-VLAN parameter. In
this case, the outer and inner tag of the incoming packets is used to match the VLAN translation rule. The
outer VLAN of the matched packet is replaced by translated service VLAN and the original inner VLAN is
not modified.
Configure a 2:2 VLAN translation rule by specifying the RESULTANT-INNER-VLAN parameter. In this
case, the original inner VLAN of the matched packet will be replaced by the specified new inner VLAN.
Usually, the 2:1 and 2:2 VLAN translations are configured on trunk ports.
When VLAN mapping entries are configured on a trunk port, the packet handling behavior is different
from an ordinary trunk port. When a packet arrives at the port, its VLAN is translated to a new VLAN.
Then, the learning and subsequent operations are based on the translated VLAN. For packets egress
from the port, the VLAN of the packet will be translated back to the original VLAN before the packet is
transmitted.
When configuring VLAN mapping entries to translate an original VLAN to an S-VLAN, the user cannot
configure another VLAN mapping entry to translate other original VLANs to the S-VLAN or configure the
VLAN mapping rule bundling C-VLANs to the S-VLAN, and vice versa.
If there is no VLAN mapping entry or rule that matches the incoming tagged packet and the VLAN
mapping miss drop option is enabled on the port, the packet will be dropped. If the VLAN mapping miss
drop option is disabled, the port-based service VLAN will be assigned for the unmatched packet.
Example
This example shows how to configure VLAN mapping entries for a trunk port.
Switch# configure terminal
Switch(config)# interface eth1/0/1
Switch(config-if)# switchport mode trunk
Switch(config-if)# switchport vlan mapping original-vlan 100 resultant–vlan 1100
Switch(config-if)# switchport vlan mapping original-vlan 200 resultant–vlan 1200
Switch(config-if)#
This example shows how to configure VLAN mapping entries for an 802.1Q tunnel port.
Switch# configure terminal
Switch(config)# interface eth1/0/2
Switch(config-if)# switchport mode dot1q-tunnel
Switch(config-if)# switchport vlan mapping original-vlan 600 resultant–vlan 1600
Switch(config-if)# switchport vlan mapping original-vlan 700 dot1q-tunnel 1700
Switch(config-if)# switchport access vlan 1600
Switch(config-if)# switchport hybrid allow vlan add
Switch(config-if)#
109-5 dot1q-tunnel insert dot1q-tag
This command is used to specify the dot1q VLAN tag insertion. Use the no command to remove the
dot1q VLAN tag insertion.
dot1q-tunnel insert dot1q-tag DOT1Q-VLAN
no dot1q-tunnel insert dot1q-tag
