cefSwitchingHCPunt2Host
Module: CISCO-CEF-MIB
OID (symbolic): CISCO-CEF-MIB::cefSwitchingHCPunt2Host
OID (numeric): 1.3.6.1.4.1.9.9.492.1.8.2.1.8
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 host (process switching path).
For most of the switching paths, the value of this object may be similar to cefSwitchingPunt. This object is a 64-bit version of cefSwitchingPunt2Host.
What is cefSwitchingHCPunt2Host?
This is the 64-bit version of cefSwitchingPunt2Host, counting packets punted to host or process switching on platforms with enough traffic to overflow the 32-bit counter. On a heavily loaded router, tracking this 64-bit counter's rate of change is one of the most direct ways to correlate a CPU spike with a specific traffic pattern escaping fast-path CEF entirely. A NOC correlating a CPU alert with this counter jumping by several million packets in the same window would have strong evidence the CPU spike is forwarding-related, not a control-plane process issue.
