cefPrefixExternalNRHCPkts
Module: CISCO-CEF-MIB
OID (symbolic): CISCO-CEF-MIB::cefPrefixExternalNRHCPkts
OID (numeric): 1.3.6.1.4.1.9.9.492.1.1.2.1.14
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: If CEF accounting is set to enable non-recursive accounting (value of cefCfgAccountingMap object in the cefCfgEntry is set to enable 'nonRecursive' accounting), then this object represents the number of non-recursive packets in the external bucket switched using this prefix.
This object is a 64-bit version of cefPrefixExternalNRPkts.
What is cefPrefixExternalNRHCPkts?
This is the 64-bit version of cefPrefixExternalNRPkts, avoiding counter wraparound for the external, recursively-resolved, non-recursive-accounting packet bucket on busy prefixes. As with its internal-bucket counterpart, this 64-bit counter becomes necessary specifically once a recursively-resolved prefix carries enough traffic that the 32-bit version would wrap within a typical monitoring interval. A heavily-used recursively-resolved transit prefix would need this 64-bit counter polled to reliably track its external-bucket packet volume over anything longer than a very short interval.
