Enterasys Networks VH-2402S specification

Forwarding Traffic with Unknown VLAN Tags

This switch only supports 256 VLANs with VLAN IDs ranging from 1 to 2048, but the IEEE 802.1Q VLAN standard allows for VLAN IDs from 1 to 4094. Therefore, if this switch is attached to endstations that issue VLAN registration requests, it will have to forward unknown VLAN tags. This traffic can only be propagated to the rest of the network if automatic VLAN registration is enabled on the switch.
