Configuring Push/Pop VLAN

VLAN aware mode provides OPB administrators with the ability to match and modify packets in the flow before forwarding them to the tool port(s).

You can configure the OPBNOS to modify the flow as below:

• Push VLAN - Push a new VLAN Tag onto the egress traffic.

• Pop VLAN - Pop(remove) the VLAN Tag from the egress traffic.

This feature is only supported on the NVIDIA platforms

Push/Pop VLAN

Reference

Command	push-vlan-tag <vid>
Description	push VLAN to traffic matching the rules configured in the map
Parameters	vlanid—within 1 to 4094
Mode	flow

Example

pbnoscli# configure terminal
pbnoscli(config)# flow flow01
pbnoscli(config-flow-flow01)# push-vlan-tag 
  <pushvlanid>          Add VLAN tag (1...4094)
pbnoscli(config-flow-flow01)# push-vlan-tag 1002
pbnoscli(config-flow-flow01)# 

//to remove push tag
pbnoscli(config-flow-flow01)# no push-vlan-tag 
pbnoscli(config-flow-flow01)# 

You can verify the configuration by using the command(s) below:

pbnoscli# show flow flow01
