Overview of the Circuit Emulation over Packet Shared Port Adapter
The following example shows an output of the show interfaces cem command on a Cisco ASR 1000 Series
Routers with the SPA-2CHT3-CE-ATM installed in the third subslot of a SIP that is installed in slot 0 for a
DS3 link:
Router# show interfaces cem 0/3/0
CEM0/3/0 is up, line protocol is up
Hardware is Circuit Emulation Interface
MTU 1500 bytes, BW 45000 Kbit/sec, DLY 0 usec,
Encapsulation CEM, loopback not set
Keepalive not supported
Last input never, output never, output hang never
Last clearing of "show interface" counters never
Input queue: 0/375/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: fifo
Output queue: 0/0 (size/max)
5 minute input rate 1536000 bits/sec, 1000 packets/sec
5 minute output rate 425000 bits/sec, 278 packets/sec
Example of the show interfaces atm Command
The following example shows an output of the show interfaces atm command on a Cisco ASR 1000 Series
Routers with the SPA-2CHT3-CE-ATM configured as clear-channel ATM T3 and installed in the second
subslot of a SIP that is installed in slot 0:
Router# show interfaces atm 0/2/0
ATM0/2/0 is up, line protocol is up
