Removing the Out-of-Band Clocking Configuration
Use the following commands to delete the various components used for out-of-band clocking:
• To remove a CEM circuit, use the no cem circuit-id command (where circuit-id is the number assigned
to the circuit). Issue the command under the virtual CEM interface where the circuit exists.
Router# conf t
Enter configuration commands, one per line.
Router(config)# int virtual-cem 0/1/24
Router(config-if)# no cem 1
Router(config-if)# end
• To remove a virtual CEM interface, use the no clock master or no clock slave command in
recovered-clock configuration mode, as shown in the following examples. Note that the virtual CEM
interface is not deleted when you remove the last CEM circuit under the interface.
Router# conf t
Enter configuration commands, one per line.
Router(config)# recovered-clock 0 1
Router(config-clock)# no clock master
Router(config-clock)# end
Router#
In the following example, the no clock slave command deletes the slave clock interface for the recovered
clock (which is 0/1):
Router# config t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# recovered-clock 0 1
Router(config-clock)# no clock slave
Router(config-clock)# end
Router#
Example: Out-of-Band Clocking Configuration
This section provides an example of how to configure out-of-band clocking between two CEM SPAs. It is
divided into several different configuration sections.
