Chapter 4 Configuring Ethernet SPAs on Cisco IOS XR Software

Configuration Tasks

Specifying the Interface Address

SPAs on Cisco XR 12000 Series Routers running Cisco IOS XR software use an addressing format that

specifies the physical location of the SIP, SPA, and interface. The interface address format is

rack/slot/subslot/port:

• rack—Specifies the rack number, 0 for the Cisco XR 12000 Series Router.

• slot—Specifies the slot number in the Cisco XR 12000 Series Router in which the MSC that contains

the SPA is installed.

• subslot—Specifies the secondary slot on the MSC where the SPA that you want to select is installed.

• port—Specifies the interface number that you want to select on the SPA:

–

For the 1-Port 10-Gigabit Ethernet SPA—0 is the only option.

–

For the 10-Port Gigabit Ethernet SPA—0 through 9

–

For the 5-Port Gigabit Ethernet SPA—0 through 4

Step 11

no shutdown

Example:

RP/0/0/CPU0:Router(config-if)# no shutdown

Removes the shutdown configuration, which forces an

interface administratively down.

• The no shutdown command passes an enable

command to the SPA, which then returns to an up or a

down state depending on the configuration and state of

the link.

Step 12

end

commit

Example:

RP/0/0/CPU0:Router(config-if)# end

RP/0/0/CPU0:Router(config-if)# commit

Saves configuration changes.

• When you issue the end command, the system prompts

you to commit changes:

Uncommitted changes found. Commit them before

exiting (yes/no/cancel)? [cancel]:

–

Entering yes saves configuration changes to the

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.
