Troubleshooting the Interface Manager
RP/0/RP0/CPU0:router# show im children ifhandle 0x03000200
SONET0/2/0/0, ifh 0x03000200 (administratively down)
SonetPath0/2/0/0, ifh 0x03000300 (administratively down)
When the interfaces are created, use the show interfaces command to examine the state. The following
sample output is from the show interfaces command for POS 0/2/0/0:
RP/0/RP0/CPU0:router# show interfaces POS 0/2/0/0
POS0/2/0/0 is up, line protocol is up
Hardware is Packet over SONET
Description: router4 POS 2\0
Internet address is 3.4.5.6/24
MTU 4474 bytes, BW 155520 Kbit
Encapsulation HDLC, crc 16, controller loopback not set, keepalive set (10 sec)
Last clearing of "show interface" counters never
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 0 bits/sec, 0 packets/sec
The following sample output from the show interfaces command shows the router summary:
