Setting the rapid switchover stale timer
Syntax
redundancy rapid-switchover 0-2147483647
Allows configuration of a timer (in seconds) for Layer 3 forwarding of packets when nonstop
switching is configured for redundancy. After failover, the route and neighbor entries in the
forwarding information base (FIB) on the active management module are marked as stale. As new
routes are added, the stale flag is reset. This continues for the number of seconds indicated by the
timer, after which all remaining stale entries (entries not re-added) are removed.
A setting of zero indicates that no Layer 3 Nonstop switching behavior is wanted. When the switch
fails over, the FIB entries and corresponding hardware entries are removed.
(Default: 45 seconds)
To display information about stale FIB routes, enter the show tech route stale command.
The VLAN ID and IP route are shown, as well as other information used only for technical support.
