Interface Descriptor (ifDescr)

Text description of the private port.

Secondary VLAN ID (cpvlanPrivatePortSecondaryVlan)

VLAN ID of the secondary VLAN.

A private port:

- accepts incoming traffic from its secondary VLAN, outgoing traffic from its associated primary VLAN, and outgoing traffic from a community or two-way community VLAN (depending on the the secondary VLAN type).
- blocks the outgoing traffic from an isolated VLAN.

Note that a port can join a secondary VLAN only after this secondary VLAN has been associated with a primary VLAN (in other words, when cpvlanVlanAssociatedPrimaryVlan has a nonzero value).
