			F I N A L D R A F T — C i s c o C o n f i d e n t i a l
DETAILED STEPS

		Command or Action		Purpose
Step 1
Step 1		configure		Enters global configuration mode.
		Example:
		RP/0/RSP0/CPU0:router# configure
Step 2
Step 2		interface MgmtEthrack/slot/CPU0/port		Enters interface configuration mode and specifies the
				Management Ethernet interface of the primary RSP.
		Example:		See Table 3-6for command parameters.
		RP/0/RSP0/CPU0:RO-C(config)# interface mgmtEth
		0/rSP0/CPU0/0
Step 3
Step 3		ipv4 address ipv4-address subnet-mask		Assigns an IP address and subnet mask to the interface.
		Example:
		RP/0/RSP0/CPU0:RO-C(config-if)# ipv4 address
		1.1.1.1	255.255.255.255
Step 4
Step 4		no shutdown		Enables the interface to carry traffic.
		Example:
		RP/0/RSP0/CPU0:router(config-if)# no shutdown
Step 5
Step 5		exit		Exits the Management Ethernet interface configuration
		Example		mode.
		Example
		RP/0/RSP0/CPU0:RO-C(config)# sh config
		Building configuration...
		interface MgmtEth0/RSP0/CPU0/0
		ipv4 address 1.1.1.1 255.255.255.255
		!
		end
Step 6
Step 6		router static address-family ipv4 unicast		Establishes a static route.
		0.0.0.0/0 default-gateway
		Example:
		RP/0/RSP0/CPU0:router(config-static)#
		address-family ipv4 unicast
Step 7
Step 7		commit		Commits the target configuration to the running
				configuration.
		Example:
		RP/0/RSP0/CPU0:RO-C(config)# commit
