Specifying the Interface Address on a SPA

SPA interface ports begin numbering with “0” from left to right. Single-port SPAs use only the port number 0. To configure or monitor SPA interfaces, you need to specify the physical location of the MSC, SPA and interface in the CLI. The interface address format is slot/subslot/port, where:

•slot—Specifies the chassis slot number in the Cisco 7304 router where the MSC is installed.

•subslot—Specifies the secondary slot of the MSC where the SPA is installed.

•port—Specifies the number of the individual interface port on a SPA.

For example, to configure the first interface (0) on a serial SPA installed in the first subslot of an MSC

(0) installed in chassis slot 3, use the the following command:

Router(config)# interface serial 3/0/0

The same slot/subslot/port format is used in similar commands for other non-channelized SPAs.

Optional Configurations

There are several standard, but optional configurations that might be necessary to complete the configuration of your serial SPA.
