3.2.4 Pass through Mode

Pass through mode is used to process traffic that is untagged or where the VLAN tag

does not match the VID of any Service or Service Group. Ingress and egress packets

processed by a Service Group or Service set to 'Pass through' mode are forwarded

without modification.

Pass through mode can be used to:

Transparently forward all unclassified traffic between two ports (both ports are 'Pass

though' mode).

Add or remove the outermost VLAN tag (Q-in-Q), depending on the direction of the

traffic (only one port is using 'Pass though' mode).

Notes:

1. Only one Service Group (sector controller) may be set to 'Pass though' mode.

2. Only one Service on a subscriber may be set to 'Pass though' mode.
