cefCfgDistributionOperState
Module: CISCO-CEF-MIB
OID (symbolic): CISCO-CEF-MIB::cefCfgDistributionOperState
OID (numeric): 1.3.6.1.4.1.9.9.492.1.4.1.1.4
Node type: OBJECT-TYPE
Type: CefOperStatus
Access: read-only
Description: The current operational state of CEF distribution.
If the cefCfgDistributionAdminState is disabled(2), then cefDistributionOperState will eventually go to the down(2) state unless some error has occurred.
If cefCfgDistributionAdminState is changed to enabled(1) then cefCfgDistributionOperState should change to up(1) only if the CEF entity is ready to forward the packets using Distributed Cisco Express Forwarding (dCEF) else it should remain in the down(2) state. The up(1) state for this object indicates that CEF entity is forwarding the packet using Distributed Cisco Express Forwarding.
What is cefCfgDistributionOperState?
This reports the actual operational state of distributed CEF, tracking cefCfgDistributionAdminState the same way cefCfgOperState tracks the main CEF admin state, down when disabled barring an error, up only once distributed forwarding is genuinely ready on the line cards. A line card that is administratively enabled for distributed CEF but whose operational state here remains down points to that specific card failing to build or sync its local FIB copy, which is a very different problem from a central RP-level CEF issue and should be diagnosed on that card specifically. If one line card out of several shows this object stuck at down while its siblings show up, that specific card is the one that failed to complete its distributed FIB synchronization and warrants isolated investigation.
