Pseudowire Configuration Notes
The vc-switching parameter must be specified at the time the VLL service is created. Note that
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.
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 CLI syntax to create pseudowire switching VLL services.
CLI Syntax: config>service# apipe service-id [customer customer-id] [vpn
vpn-id] [vc-type {atm-vcc|atm-sdu|atm-vpc|atm-cell}] [vc-switching]
description description-string
spoke-sdp sdp-id:vc-id
CLI Syntax: config>service# epipe service-id [customer customer-id][vpn
vpn-id][vc-switching]
description description-string
spoke-sdp sdp-id:vc-id
CLI Syntax: config>service# fpipe service-id [customer customer-id][vpn
vpn-id] [vc-type {fr-dlci}] [vc-switching]
description description-string
spoke-sdp sdp-id:vc-id
CLI Syntax: config>service# ipipe service-id [customer customer-id][vpn
vpn-id] [vc-switching]
description description-string
spoke-sdp sdp-id:vc-id
The following displays an example of the command usage to configure VLL pseudowire
switching services:
Example:config>service# apipe 1 customer 1 vpn 1 vc-switching create
config>service>apipe$ description “Default apipe description for
service id 100”
config>service>apipe# spoke-sdp 3:1 create
config>service>apipe>spoke-sdp# exit
config>service>apipe# spoke-sdp 6:200 create
config>service>apipe>spoke-sdp# exit
config>service>apipe# no shutdown
