Note. The display can include AP access ports and wired authentication ports, because WSS Software dynamically adds these ports to a VLAN when handling user traffic for the VLAN.

(For information about the fields in the output, see the Nortel WLAN Security Switch 2300 Software Command Reference.)

Managing the Layer 2 Forwarding Database

An WSS switch uses a Layer 2 forwarding database (FDB) to forward traffic within a VLAN. The entries in the forwarding database map MAC addresses to the physical or virtual ports connected to those MAC addresses within a particular VLAN. To forward a packet to another device in a VLAN, the WSS switch searches the forwarding database for the packet’s destination MAC address, then forwards the packet out the port associated with the MAC address.
