Vlan Forwarding - Packets Are Already Tagged At The Ethernet Interface; Vlan Tagging - Interface Will Add And Remove Tags - Avaya 1000 Series Configuration Manual

VLAN Forwarding - Packets are already tagged at the
Ethernet interface
Packets are received and transmitted in tagged format. Forwarding decision is made by the a
vlanfwd mapping table of VLAN ID to Interface. Optional: The VLAN forwarding decision can
also be made by L2 MAC Address.
interface ethernet 0
ip address 192.168.0.1 30
exit
vlanfwd
add vlanid 75 ethernet0
add vlanid 75 wan
add vlanid 130 ethernet0
add vlanid 130 wan
macbridge
exit
exit
Note:
In this example, the statement ip address 192.168.0.1 30 is a dummy address and will not
be used for forwarding or IP access. It is required for the interface to come active.
Note:
Packets are received on VLANs 75 and 130 from a switch upstream from ethernet 0. They
are forwarded based upon the vlanfwd rules.
Note:
The macbridge statement cause the forwarding decision to be made based upon the VLAN
Tag and L2 MAC Address. Otherwise the VLAN will be forwarded based upon the tag.

VLAN Tagging - Interface will add and remove tags

The interface will transmit and receive untagged packets. On receipt, the packets will be
tagged, and tags will be stripped on transmission. This example would be identical to the VLAN
Forwarding example, except that only a single VLAN is supported on the Ethernet.
interface ethernet 0
ip address 192.168.0.1 30

vlanid 10
