Command History

Usage Guidelines The class cem command allows you to configure CEM interface parameters in a class that is applied to

CEM interfaces together. A class cem command includes the following configuration settings:

• dejitter-buffer dejitter-in-ms

• idle-pattern 8-bit-idle-pattern

• payload-size payload-size-in-ms

Note You can improve the performance of packet reordering on TDM/PWE connections by using the

increasing the size of the dejitter buffer using the dejitter-buffer parameter.

Examples The following example shows how to configure CEM interface parameters:

Router# config t

Router(config)# class cem mycemclass

Router(config-cem-class)# dejitter-buffer 10

Router(config-cem-class)# exit

Router(config)# interface cem 0/0

Router(config-if)# no ip address

Router(config-if)# cem 0

Router(config-if-cem)# xconnect 10.10.10.10 200 encapsulation mpls

Router(config-if-cem-xconn)# cem class mycemclass

Router(config-if-cem)# exit

Router(config-if)# exit

Router(config)# exit
