Chapter 22 Configuring Clocking

Configuring Network Clock for Cisco ASR 901 Router

DETAILED STEPS

	Command or Action	Purpose
Step 1	enable	Enables privileged EXEC mode.
		• Enter your password if prompted.
	Example:
	Router> enable
Step 2	configure terminal	Enters global configuration mode.
	Example:
	Router# configure terminal
Step 3	interface	Enters interface configuration mode.
	Example:
	Router(config)# interface
Step 4	esmc mode {tx rx}	Enables the ESMC process at the interface level. The no
		form of the command disables the ESMC process.
	Example:
	Router(config-if)# esmc mode tx
Step 5	network-clock source quality-level	Configures the QL value for ESMC on a gigabitethernet
	value {tx rx}	port. The value is based on global interworking options:
	Example:	• If Option 1 is configured, the available values are
		QL-PRC, QL-SSU-A, QL-SSU-B, QL-SEC, and
	Router(config-if)# network-clock	QL-DNU.
	source quality-level <value> tx	• If Option 2 is configured with GEN 2, the available
		values are QL-PRS, QL-STU, QL-ST2, QL-TNC,
		QL-ST3, QL-SMC, QL-ST4, and QL-DUS.
		• If Option 2 is configured with GEN1, the available
		values are QL-PRS, QL-STU, QL-ST2, QL-SMC,
		QL-ST4, and QL-DUS
Step 6	esmc mode ql-disabled	Enables the QL-disabled mode.
	Example:
	Router(config-if)# esmc mode
	ql-disabled

Note By disabling Rx on an interface, any ESMC packet received on the interface shall be discarded. By disabling Tx on an interface, ESMC packets will not be sent on the interface; any pending Switching Message Delay timers (TSM) are also stopped.
