Troubleshooting NSF Features

To troubleshoot the NSF feature, use the following commands in privileged EXEC mode, as needed:
Command
Router# clear cef epoch
Router# debug isis nsf [detail]
Router# debug ospf nsf [detail]
Router# show cef nsf
Router# show cef state
Router# show clns neighbors
Router> show ip bgp
Router# show ip bgp neighbor
Router# show ip cef
Router> show ip ospf
Router> show ip ospf neighbor [detail]

Purpose
Begins a new epoch and increments the epoch number for a CEF table.
Displays information about the IS-IS state during a Cisco NSF restart.
Displays debugging messages related to OSPF Cisco NSF commands.
Displays the current NSF state of CEF on both the active and standby RSPs.
Displays the state of CEF on a networking device.
Display both end-system (ES) and intermediate system (IS) neighbors.
Displays entries in the BGP routing table.
Displays information about the TCP and BGP connections to neighbor
devices.
Displays entries in the FIB that are unresolved, or displays a FIB summary.
Displays general information about OSPF routing processes.
Displays OSPF-neighbor information on a per-interface basis.
