802.1Q Overview
The port can only be assigned to one untagged VLAN (in every case, this will be the default VLAN). In
the example above the default VLAN is VLAN 1. The port can be assigned to as many 802.1Q VLANs as
necessary, up to 4093 per port or 32768 VLAN port associations.
For the purposes of Quality of Service (QoS), 802.1Q ports are always considered to be trusted ports. For
more information on QoS and trusted ports, see
Alcatel's 802.1Q tagging is done at wire speed, providing high-performance throughput of tagged frames.
The procedures below use CLI commands that are thoroughly described in "802.1Q Commands" of the
OmniSwitch CLI Reference Guide.
Note. 802.1Q on the OmniSwitch 6800 does not have the "force tag internal" feature, available on other
OmniSwitch products.
