Configuring VLAN Modes

VLAN modes in APB provide administrators to match flow based on the VLAN tag in the packet and redirect to the tool ports

APB supports two VLAN modes;

• VLAN-aware mode will match traffic based on both configured ingress-VLAN and VLAN configured in flow rules

• VLAN-unaware mode will allow all VLAN traffic and does not follow the ingress-VLAN configuration

By default, the port is in VLAN-aware mode and will accept traffic tagged with VLAN 'n+2', where 'n' is the port number i.e. Eth2+2 = VLAN 4

Reference

Command	mode vlan-aware mode vlan-unaware
Description	vlan-aware: used for matching packets based on VLAN id
Parameters	None
Mode	INTERFACE

This feature is only supported on the NVIDIA platforms and is applicable only for network ports.

Example

pbnoscli# configure terminal
pbnoscli(config)# interface ethernet Ethernet16/1
pbnoscli(config-if)# mode vlan-
  vlan-aware            dot1_q mode
  vlan-unaware          q_inq mode
pbnoscli(config-if)# mode vlan-aware 
pbnoscli(config-if)# 

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

pbnoscli# show interface npb Ethernet16/1
