Shutting Down and Restarting an Interface on a SPA
You can shut down and restart any of the interface ports on a SPA independently of each other. Shutting down
an interface stops traffic and then enters the interface into an “administratively down” state.
If you are preparing for an OIR of a SPA, it is not necessary to independently shut down each of the interfaces
prior to deactivation of the SPA. You do not need to independently restart any interfaces on a SPA after OIR
of a SPA or SIP. For more information about performing an OIR for a SPA, see the Configuring the
Encapsulation Type, on page 202.
To shut down an interface on a SPA, use the following command in interface configuration mode:
PurposeCommand
Disables an interface.Router(config-if)# shutdown
To restart an interface on a SPA, use the following command in interface configuration mode:
PurposeCommand
Restarts a disabled interface.Router(config-if)# no shutdown
Verifying the Interface Configuration
Besides using the show running-configuration command to display your Cisco ASR 1000 Series Routers
configuration settings, you can use the show interfaces pos and show controllers pos commands to get
detailed information on a per-port basis for your POS SPAs.
Verifying Per-Port Interface Status
To find detailed interface information on a per-port basis for the POS SPAs, use the show interfaces pos
command. For an example of the command output for a POS SPA at location 0/3/0, see the following:
router# show interfaces POS 0/3/0
POS0/3/0 is administratively down, line protocol is down
Hardware is Packet over Sonet
MTU 4470 bytes, BW 155000 Kbit, DLY 100 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation HDLC, crc 16, loopback not set
Keepalive set (10 sec)
Scramble disabled
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: 0/40 (size/max)
5 minute input rate 0 bits/sec, 0 packets/sec
