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 SIP, SPA, and
interface in the CLI. The interface address format is slot/subslot/port, where:
• slot—Specifies the chassis slot number in the Cisco ASR 1000 Series Aggregation Services Routers
where the SIP is installed.
• subslot—Specifies the slot of the SIP where the SPA is installed.
• port—Specifies the number of the individual interface port on a SPA.
The following example shows how to specify the first interface (0) on a SPA installed in the first subslot of
a SIP (0) installed in chassis slot 2:
Router(config)# interface serial 2/0/0
This command shows a serial SPA as a representative example, however the same slot/subslot/port format is
similarly used for other SPAs (such as ATM and POS) and other non-channelized SPAs.
For more information about identifying slots and subslots, see the Required Configuration Tasks, on page
223.
Optional Configurations
There are several standard, but optional configurations, that might be necessary to complete the configuration
of your serial SPA.
Configuring Data Service Unit Mode
Configure the SPA to connect with customer premises Data Service Units (DSUs) by setting the DSU mode.
Subrating a T3 or E3 interface reduces the peak access rate by limiting the data transfer rate.
To configure the DSU mode and bandwidth, use the following commands:
PurposeCommand
Enters global configuration mode.Router# configure terminal
Selects the interface to configure and enters interface
configuration mode.
Router(config)# interface serial slot/subslot/port
