Using the Control Word
The control word is mandatory for Cpipe SAToP and CESoPSN configurations. It is
optional for Apipe, Epipe, and Ipipe configurations.
When the control word is enabled, the Admin Control Word is set to Preferred. Both sides of
the VLL must be configured with a matching control word, either both enabled or both
disabled, for the pipe to be up.
The control word state will be set to True or False depending on what is configured, either
enabled (True) or disabled (False).
Example: config>service# cpipe 2100 customer 1
config>service>cpipe$ description “Default cpipe
description for service id 2100”
config>service>cpipe$ sap 1/2/7.1:4 create
config>service>cpipe>sap$ description “Default sap
description for service id 2100”
config>service>cpipe>sap$ exit
config>service>cpipe# spoke-sdp 1:2001 create
config>service>cpipe>spoke-sdp$ control-word
config>service>cpipe>spoke-sdp$ exit
config>service>cpipe# no shutdown
The following example displays the control word configuration output for a Cpipe service.
*A:ALU-Dut-B>config>service>cpipe# info
----------------------------------------------
description "Default cpipe description for service id 2100"
sap 1/2/7.1:4 create
description "Default sap description for service id 2100"
exit
spoke-sdp 1:2001 create
control-word
exit
no shutdown
----------------------------------------------
*A:ALU-Dut-B>config>service>cpipe#
Control word cannot be disabled on Cpipe services. To disable the control word option on
Apipe, Epipe, or Ipipe services, use the
no control-word command.
Example: config>service>apipe# spoke-sdp 1:2001 no control-word
config>service>apipe>spoke-sdp$ exit
