Binding an AC to a cross-connect
This task is mutually exclusive with Ethernet link aggregation. If an Ethernet interface has been added to
a link aggregation group, you cannot bind a service instance on the interface to a cross-connect, and
vice versa.
On a Layer 2 Ethernet or Layer 2 aggregate interface, you can create a service instance and bind it to
a cross-connect. The service instance matches packets received on that interface. The matching packets
are then forwarded to the bound PW or another AC. A service instance can match all packets, tagged
packets, or untagged packets.
To bind a service instance to a non-BGP cross-connect:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter cross-connect group
view.
xconnect-group group-name N/A
3. Enter cross-connect view. connection connection-name N/A
4. Bind the service instance on
the interface to the
cross-connect.
ac interface interface-type
interface-number service-instance
instance-id [ access-mode
{ ethernet | vlan } ]
By default, no service instance is
bound to the cross-connect.
To bind a service instance to a BGP cross-connect:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter cross-connect group
view.
xconnect-group group-name N/A
3. Enter cross-connect group
auto-discovery view.
auto-discovery bgp N/A
4. Enter site view.
site site-id [ range range-value ]
[ default-offset default-offset-value ]
N/A
5. Enter auto-discovery
cross-connect view. connection remote-site-id
remote-site-id
N/A
6. Bind the service instance on
the interface to the BGP
cross-connect.
ac interface interface-type
interface-number service-instance
instance-id [ access-mode
{ ethernet | vlan } ]
By default, no service instance is
bound to the BGP cross-connect.
Configuring PW redundancy
This task includes the following configurations:
• Create a backup PW for the primary PW.
• Specify whether to switch traffic from the backup PW to the primary PW when the primary PW
recovers, and specify the wait time for the switchover.
