Description: Number of SIP3 CRC errors.

What is lportSmdsCntSip3Crc32Errors?

This counts SIP3 PDUs that failed CRC-32 integrity verification on this interface, a basic data-corruption check distinct from all the structural and field-validity checks in the surrounding counters. An admin treats a rising count here as evidence of physical-layer or transport-level bit errors corrupting SMDS traffic, rather than a logical or formatting problem in how PDUs are constructed. For example, lportSmdsCntSip3Crc32Errors climbing in step with physical-layer error counters elsewhere on the same interface would confirm a line-quality issue is the actual root cause, not an application-level SMDS bug.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.129
snmpwalk -v2c -c public <target> CASCADE-MIB::lportSmdsCntSip3Crc32Errors

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.129.1
snmpget -v2c -c public <target> CASCADE-MIB::lportSmdsCntSip3Crc32Errors.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.5.1.1.129.1 i <value>
