Arista Switch - CRC Errors - Ext

Description

Monitor the Arista CRC errors counter value and counter delta, where the counter value represents the exact value, and Delta refers to the difference between the current error count and the previous error count.[RMON-MIB :: etherStatsCRCAlignErrors : 1.3.6.1.2.1.16.1.1.1.8] The data source OID in the RMON MIB is “1.3.6.1.2.1.16.1.1.1.2”. This OID corresponds to the ifIndex OID in the IF-MIB. Therefore, we map this data source OID result to the IF-MIB and consider it as the component information retrieved from the IF-MIB with OID “1.3.6.1.2.1.31.1.1.1.1”. Arista Networks EOS version 4.28.6.1M running on an Arista Networks DCS-7280SR3-48YC8. SNMPSysObjId=1.3.6.1.4.1.30065.1.3011.7280.3735.3.48.1654.8.
