Troubleshooting OC-3c, OC-12c, and OC-48c Interfaces
Follow these steps to display the memory management and error counters of an OC-3c, OC-12c, or
OC-48c ATM interface:
Step 1 Use the show controllers atm card/subcard/port command to check memory management and error
counters.
Switch# show controllers atm 9/0/0
IF Name: ATM9/0/0, Chip Base Address: 0xBC480000 Framer Address: 0xBC488000
Port type: OC48c Port rate: 2488000 Kbps Port medium: SM Fiber
Port status (0x8021) - LINE AIS LCD
Loopback:None Flags:8300
TX Led: Traffic Pattern RX Led: Steady Red
TX clock source: network-derived
Framing mode: sts-48c
Cell payload scrambling on , Sts-stream scrambling on
OC48c counters:
Key: txcell - # cells transmitted
rxcell - # cells received
b1 - # section BIP-8 errors
b2 - # line BIP-8 errors
b3 - # path BIP-8 errors
ocd - # out-of-cell delineation errors
g1 - # path FEBE errors
z2 - # line FEBE errors
chcs - # correctable HEC errors
uhcs - # uncorrectable HEC errors
