must specify the physical location of the SIP, SPA, and interface in the command line interface (CLI). The
interface address format is
slot/subslot/port
, where:
•
slot
—
Specifies the chassis slot number in the Cisco ASR 1000 Series Router in which the SIP is installed
•
subslot
—
Specifies the secondary slot of the SIP in which 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 that is installed in subslot 1 of
the SIP in chassis slot 0:
Router(config)#
interface cem 0/1/0
Configuring Port Usage: An Overview
The SPA-1CHOC3-CE-ATM can be configured to run only in the CEM mode. The 2-Port Channelized T3/E3
ATM CEoP SPA, introduced in Cisco IOS XE Release 3.4.0S, can be configured to run only in the ATM
mode. Effective from Cisco IOS XE Release 3.6.0S, the 2-Port Channelized T3/E3 ATM CEoP SPA supports
the CEM mode, but does not support the IMA mode. Effective from Cisco IOS XE Release 3.10.0S, The
24-port channelized T1E1 SPA supported ATM mode on the SPA-24CHT1-CE-ATM.
The following sections show how to configure each of the SPAs for the CEM mode.
