ACX Series Universal Access Router Configuration Guide

You can configure E-LAN and E-LINE services by using bridge domains.
On ACX Series routers, you can configure bridge domains by using the following methods:
Bridge domain without a
Bridge domain with the
Bridge domain with a single
Bridge domain with a
vlan-id-list
NOTE: The Layer 2 CLI configurations and show commands for ACX5048
and ACX5096 routers differ compared to other ACX Series routers. For more
information, see
and ACX5096 Routers" on page
When you configure E-LAN and E-LINE services using a bridge domain without a
statement, the bridge domain should explicitly be normalized to a service VLAN
number
ID and TPID by configuring an input VLAN map under a logical interface. Explicit
normalization is required when a logical interface's outer VLAN ID and TPID is not the
same as the service VLAN ID and TPID of the service being configured using a bridge
domain.
The following input VLAN map functions are supported in ACX Series routers:
—Add a new VLAN tag to the top of the VLAN stack.
push
swap —Replace the outer VLAN tag of the VLAN stack in a frame.
—Remove a VLAN tag from the top of the VLAN tag stack.
pop
swap-swap —Replace both the outer and inner VLAN tags of the frame.
—Push two VLAN tags on top of the VLAN stack.
push-push
NOTE: push-push
packet already has a VLAN tag.
The following VLAN map functions are not supported in ACX Series routers:
—Replace the outer VLAN tag of the frame and add a new VLAN tag to the
swap-push
top of the VLAN stack.
—Remove the outer VLAN tag of the frame and replace the inner VLAN tag
pop-swap
of the frame.
—Remove both the outer and inner VLAN tags of the frame.
