The translation mechanism comprises a plurality of forwarding tables, each of which contains entries having unique index values that translate to selection signals for ports destined to received the data frames. Each port is associated with a unique index value and a VLAN identifier to facilitate multicast data transfers within the switch at accelerated speeds and addressing capabilities. | |
