Troubleshooting DS3 and E3 Interfaces
Follow these steps to display the memory management and error counters of a DS3 or E3 ATM interface:
Step 1 Use the show controllers atm card/subcard/port command to check memory management and error
counters.
Switch# show controllers atm 3/0/0
IF Name: ATM3/0/0, Chip Base Address: A8C08000
Port type: DS3 Port rate: 45000 Kbps Port medium: Coax
IF Name: ATM3/0/0, Chip Base Address: A8C08000
Port type: DS3 Port rate: 45000 Kbps Port medium: Coax
Port status hex: 800D - LOS OOF ADM_OOCD
Loopback:None Flags:8000
TX Led: Traffic Pattern RX Led: Steady Red
TX clock source: free-running
DS3 Framing Mode: cbit adm
Contents of Rx trail trace buffer:
Contents of Rx exp trail trace buffer:
Contents of Tx trail trace buffer:
FERF on AIS is on
FERF on LCD is on (n/a in PLCP mode)
FERF on RED is on
FERF on OOF is on
FERF on LOS is on
LBO: <= 225'
PDH counters:
Key: txcell - # cells transmitted
rxcell - # cells received
lcv - # line code violations
ferr - DS3: # F-bit/M-bit errors; E3: # framing errors
exzs_ier - T3: # excessive zeros; E3 G.832: # iec errors
perr - DS3: # P-bit errors; E3 G.832: # BIP-8 errors
cperr - DS3: # path parity errors
febe - DS3 or E3 G.832: # FEBE errors
b1 - # PLCP BIP errors
fe - # PLCP framing pattern octet errors
plcp_febe- # PLCP FEBE errors
hcs - # uncorrectable HEC errors
uicell - # unassigned/idle cells dropped
