Forwarding Traffic With Unknown Vlan Tags - Enterasys Vertical Horizon VH-2402S2 Configuration Manual

Forwarding Traffic with Unknown VLAN Tags

The VH-2402S2 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 a 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.
