0/SM0/SP           FC/S(SP)         N/A                              IOS-XR RUN      PWR,NSHUT,MON

Note: FC=Fan Card
SM=Switch Module
AM=Alarm Module

Node0/0/SP - Rack0, Slot0, Module Service Processor
0/0/CPU0 - Rack0, Slot0, CPU0 - Interfaces with the PLIM 16OC48-POS/DPT
0/RP0/CPU0  - Rack0, Route Processor, CPU0

Type
Type of Card

PLIM
Idenifies Physical Layer Interface Module

State
shows the state of the node

Config State
PWR- Power
SHUT-Shut
MON-Monitor
NPWR- No Power
NSHUT-No Shut
UMON- Un Monitor


RP/0/RP0/CPU0:CRS-19(config)#show ipv4 interface brief

Interface                      IP-Address      Status                Protocol
POS0/1/0/0                     10.0.0.1        UP                    UP
TenGigE0/3/0/0                 unassigned      Shutdown              Down
TenGigE0/3/0/2                 unassigned      Shutdown              Down
MgmtEth0/RP0/CPU0/0            unassigned      Shutdown              Dow

Loopacks do not follow the r/s/m/p naming

POS0/1/0/0  - Rack0, Slot1, Module0, port 0
MgmtEth0/RP0/CPU0/0 - RP0, CPU0, Port0
TenGigE0/3/0/2 - Rack0, Slot3, Module0, Port2
