Configuring Serial Interfaces on Cisco IOS XR Software

How to Configure Serial Interfaces

	Command or Action	Purpose
Step 9
	scramble	(Optional) Enables payload scrambling on the interface.
		Note	Payload scrambling is disabled on the interface.
	Example:
	RP/0/0/CPU0:ios(config-if-serial)# scramble
Step 10
	transmit-delay hdlc-flags	(Optional) Specifies a transmit delay on the interface.
		Values can be from 0 to 128.
	Example:	Note	Transmit delay is disabled by default (the transmit
	RP/0/0/CPU0:ios(config-if-serial)#		delay is set to 0).
	transmit-delay 10
Step 11
	exit	Exits serial configuration mode.
	Example:
	RP/0/0/CPU0:router(config-if-serial)# exit
	RP/0/0/CPU0:router(config-if)#
Step 12
	no shutdown	(Optional) Enables the serial interface. Use this command if
		the interface was shut down.
	Example:	Note	Serial interfaces are enabled by default. However, if
	RP/0/0/CPU0:router(config-if)# no shutdown		the card or router is reset and the serial interface is
			not configured, then it comes up in the shutdown
			state.
Step 13
	end	Saves configuration changes.
	or	• When you issue the end command, the system prompts
	commit		you to commit changes:
			Uncommitted changes found, commit them before
	Example:		exiting(yes/no/cancel)? [cancel]:
	RP/0/0/CPU0:router(config)# end		– Entering yes saves configuration changes to the
	or
	RP/0/0/CPU0:router(config)# commit		running configuration file, exits the configuration
			session, and returns the router to EXEC mode.
			– Entering no exits the configuration session and
			returns the router to EXEC mode without
			committing the configuration changes.
			– Entering cancel leaves the router in the current
			configuration session without exiting or
			committing the configuration changes.
		• Use the commit command to save the configuration
			changes to the running configuration file and remain
			within the configuration session.
Step 14
	show interfaces serial instance	Displays information about the interface.
	Example:
	RP/0/0/CPU0:router# show interfaces serial
	0/0/3/0/5:20
