cRC
Module: CISCO-VISM-DSX1-MIB
OID (symbolic): CISCO-VISM-DSX1-MIB::cRC
OID (numeric): 1.3.6.1.4.1.351.110.4.3.1.3.2.1.6
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The accumulated number of P Bit code violations encountered on the DS1 interface.
What is cRC?
This Counter32 accumulates the number of P-bit code violations (CRC errors) encountered on this DS1 interface. P-bit CRC errors indicate framing/CRC integrity problems distinct from line code violations, so an admin tracks this separately to distinguish CRC-related framing issues from raw signal-level line coding issues. For example, a line showing high cRC counts but low lCV counts would point an admin toward a CRC/framing configuration mismatch rather than a physical cabling problem.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.351.110.4.3.1.3.2.1.6 snmpwalk -v2c -c public <target> CISCO-VISM-DSX1-MIB::cRC
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.351.110.4.3.1.3.2.1.6.1 snmpget -v2c -c public <target> CISCO-VISM-DSX1-MIB::cRC.1
