Avaya P460 Layer 2 Features
CAM Table€
It might be inefficient if the Avaya P460 could not “remember” which MAC address
was accessible from which port, that is, where a specific device is attached.
Therefore, the P460 stores a mapping of learned MAC addresses to port and VLANs
in the CAM table. The switch then checks subsequent frames. If the MAC address
appears in the CAM Table, then the packet is forwarded to the appropriate port.
If the MAC address does not appear in the CAM table, or the MAC Address
mapping has changed, then the frame is duplicated and copied to all the ports. Once
a reply is received, the CAM table is updated with the new address/VLAN port
mapping.
The CAM table size in the Avaya P460 is a minimum of 4k and a maximum of 8k.
