Using Spoke SDP Control Words
When control word is enabled, the Admin ControlWord is set to Preferred. It is necessary that both
sides of the VLL have control word enabled or disabled for the pipe to be up.
The control word state will be set to True or False depending on what is configured on both sides
of the VLL, either enabled (True) or disabled (False). When both sides are enabled (True) then the
state is True. If one side is enabled (True) but the other side is disabled (False), then the state is
False.
The command structure is the same for Ipipe and Apipe services. Apipe service data unit and
Fpipes do not need to be specified.
Example: config>service# epipe 2100 customer 1
config>service>epipe$ description "Default epipe description
for service id 2100"
config>service>epipe$ sap 1/2/7:4 create
config>service>epipe>sap$ description "Default sap description
for service id 2100"
config>service>epipe>sap$ exit
config>service>epipe# spoke-sdp 1:2001 create
config>service>epipe>spoke-sdp$ control-word
config>service>epipe>spoke-sdp$ exit
config>service>epipe# no shutdown
The following displays the configuration:
*A:ALA-Dut-B>config>service>epipe# info
----------------------------------------------
description "Default epipe description for service id 2100"
sap 1/2/7:4 create
description "Default sap description for service id 2100"
exit
spoke-sdp 1:2001 create
control-word
exit
no shutdown
----------------------------------------------
*A:ALA-Dut-B>config>service>epipe#
To disable the control word on spoke-sdp 1:2001:
Example:config>service>epipe# spoke-sdp 1:2001 no control-word
config>service>epipe>spoke-sdp$ exit
*A:ALA-Dut-B>config>service>epipe# info
----------------------------------------------
description "Default epipe description for service id 2100"
sap 1/2/7:4 create
description "Default sap description for service id 2100"
exit
spoke-sdp 1:2001 create
