debug ip sync

Displays debugging information about IP synchronization and faults in synchronization.
Syntax
debug ip sync [ arp ip-address | arp-all | cache ip-address | cache-all | default-route | download | next-hop redownload | route ip-address [ ip-mask ] |route-all | show | stats {clear | show } ]
no debug ip sync[ arp ip-address | arp-all | cache ip-address | cache-all | default-route | download | next-hop redownload | route ip-address [ ip-mask ] |route-all | show | stats {clear | show } ]
Parameters
