Configuring the Circuit Emulation over Packet Shared Port Adapter
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.
