Description: The VLAN ID of the secondary VLAN configured on this private port. A private port is a port that allows the ingress traffic of the secondary VLAN as well as egress traffic of its associated primary VLAN, but blocks the egress traffic of the isolated VLAN while allowing the egress traffic of the community or twoWayCommunity VLAN depending on the type of the secondary VLAN.

Note that a port can join a secondary VLAN only after this secondary VLAN has been associated with a primary VLAN, i.e., the cpvlanVlanAssociatedPrimaryVlan has a non-zero value. The default value of 0 for this object means this port has not joined any secondary VLAN yet.

What is cpvlanPrivatePortSecondaryVlan?

Sets the secondary VLAN ID assigned to a private port, which carries secondary VLAN traffic inbound and its associated primary VLAN traffic outbound while blocking traffic from other isolated ports.
