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
Encapsulation Type, on page
To shut down an interface on a SPA, use the following command in interface configuration mode:
Command
Router(config-if)# shutdown
To restart an interface on a SPA, use the following command in interface configuration mode:
Command
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

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
