cefStatsPrefixHCDeletes
Module: CISCO-CEF-MIB
OID (symbolic): CISCO-CEF-MIB::cefStatsPrefixHCDeletes
OID (numeric): 1.3.6.1.4.1.9.9.492.1.8.1.1.7
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: Number of delete operations performed to the FIB database for the specified IP prefix length. This object is a 64-bit version of cefStatsPrefixDelete.
What is cefStatsPrefixHCDeletes?
This is the 64-bit counterpart of cefStatsPrefixDeletes, tracking FIB delete operations for a given prefix length with a much larger rollover ceiling. As with the other high-capacity CEF stats, this exists so long-running monitoring on high-churn routers doesn't misread a 32-bit counter wrap as a drop in delete activity. A NOC polling FIB delete activity every 15 minutes on a router handling full BGP tables would graph this object rather than the 32-bit version to avoid wrap-related sawtooth artifacts.
