Pseudowire configuration notes

The vc-switching parameter must be specified at the time the VLL service is created.

Note: When the vc-switching parameter is specified, you are configuring an S-PE. This is a pseudowire switching point (switching from one pseudowire to another). Therefore, you cannot add a SAP to the configuration.

Example: Error generated when adding a SAP to a pseudowire

The following example show the configuration when a SAP is added to a pseudowire. The CLI generates an error response if you attempt to create a SAP. VC switching is only needed on the pseudowire at the S-PE.

*A:ALA-701>config>service# epipe 28 customer 1 create vc-switching
*A:ALA-701>config>service>epipe$ sap 1/1/3 create
MINOR: SVCMGR #1311 SAP is not allowed under PW switching service
*A:ALA-701>config>service>epipe$

Use the following syntax to create pseudowire switching VLL services.

config>service# epipe service-id [customer customer-id][vpn vpn-id] [vc-
switching]
description description-string
spoke-sdp sdp-id:vc-id

Example: Configuring VLL pseudowiare switching services

The following example shows command usage to configure VLL pseudowire switching services.

*A:7210SAS>config>service# info

            description "Default epipe description for service id 1"
            spoke-sdp 1:1 vc-type vlan create
                description "Description for Sdp Bind 1 for Svc ID 1"
                ingress
                    vc-label 4501
                exit
                egress

                    no shutdown
                exit

                ingress
                    vc-label 5501
                exit
                egress

*A:7210SAS>config>service#

Example: S-PE1 configuration

Note: Note that specifying the vc-switching parameter enables a VC cross-connect so the service manager does not signal the VC label mapping immediately but puts this into passive mode.

The following example shows configuration output for S-PE1.

*A:ALA-S-PE1>config>service>epipe# info
----------------------------------------------
...
spoke-sdp 2:200 create
exit
spoke-sdp 3:300 create
exit
no shutdown
----------------------------------------------
*A:ALA-S-PE1>config>service>epipe#

Example: S-PE2 configuration

Note: Note that specifying the vc-switching parameter enables a VC cross-connect so the service manager does not signal the VC label mapping immediately but puts this into passive mode.

The following example shows configuration output for S-PE2.

*A:ALA-S-PE2>config>service>epipe# info
----------------------------------------------
...
spoke-sdp 2:200 create
exit
spoke-sdp 3:300 create
exit
no shutdown
