cefSwitchingHCPunt
Module: CISCO-CEF-MIB
OID (symbolic): CISCO-CEF-MIB::cefSwitchingHCPunt
OID (numeric): 1.3.6.1.4.1.9.9.492.1.8.2.1.6
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: Number of packets that could not be switched in the normal path and were punted to the next-fastest switching vector. This object is a 64-bit version of cefSwitchingPunt.
What is cefSwitchingHCPunt?
This is the 64-bit version of cefSwitchingPunt, tracking punted packets on high-volume interfaces without wrapping as quickly. Monitoring this on a busy platform matters because sustained high punt rates translate directly into elevated CPU and process-switching load, which can degrade overall router performance well beyond just the punted flows. If this counter grows by millions of packets per hour on a core router, that CPU overhead could start affecting unrelated control-plane protocols like BGP or OSPF that share the same processor.
