Configuring Pseudowire
Configuring CEM Classes
A CEM class allows you to create a single configuration template for multiple CEM pseudowires.
Note • Cisco IOS release 15.3(3)S automatically enables forward-alarm ais configuration (under the
config-controller configuration mode). To disable this configuration, use the no forward-alarm ais
command.
• The forward-alarm ais configuration is applicable only for CESoP. It is not supported for SAToP.
• You must run the no forward-alarm ais command before using CESoP with controllers in loopback
(either through loopback command under controller or by using a physical loopback jack).
• Though the forward-alarm ais command (and its no form) was not supported in previous releases,
the Cisco ASR 901 router behaved as if this command was configured under the controller interface.
