Verifying Out-of-Band Clocking

This section lists the show commands that you can use to verify the out-of-band clocking configuration.

Configuring the Circuit Emulation over Packet Shared Port Adapter
Purpose
Specifies the slot and subslot of the CEM SPA from which the master clock
is recovered.
Creates a virtual CEM interface to represent the clock slave for out-of-band
clocking.
Exits from the Clock configuration mode and enters the global configuration
mode.
Enters configuration mode for the virtual CEM interface that represents the
clock slave.
• slot /subslot is the slot and subslot of the SPA from which the master
clock was recovered (Step
• port is always 24.
Creates a CEM attachment circuit for the clock slave. The circuit-id value
can be:
• 0—The primary clock source.
• 1—The secondary clock source.
You can configure up to two CEM circuits, one for each of two master
Note
clock signals.
Configures an out-of-band channel (pseudowire) to carry the clock signal.
• peer-router-id is the IP address of the router that is connected to the
source TDM device.
• vcid is a 32-bit identifier for the pseudowire.
• encapsulation mpls sets MPLS for the tunneling mode.
Use the same VCID for the master and slave clock pseudowires;
Note
otherwise, the clock channel does not come up.
Exits CEM interface configuration mode and returns you to privileged EXEC
mode.
