Glbp Timers - Cisco Catalyst 3650 series Command Reference Manual

glbp timers

glbp timers
To configure the time between hello packets sent by the Gateway Load Balancing Protocol (GLBP) gateway
and the time that the virtual gateway and virtual forwarder information is considered valid, use the glbp timers
command in interface configuration mode. To restore the timers to their default values, use the no form of
this command.

160
GLBP group number in the range from 0 to 1023.
(Optional) Specifies that the following (hellotime or
holdtime) argument value will be expressed in
milliseconds rather than seconds.
Hello interval. The default is 3 seconds (3000
milliseconds).
Time before the virtual gateway and virtual forwarder
information contained in the hello packet is
considered invalid. The default is 10 seconds (10,000
milliseconds).
Specifies time interval during which the active virtual
gateway (AVG) for a Gateway Load Balancing
Protocol (GLBP) group continues to redirect clients
to a secondary active virtual forwarder (AVF) and
time-out values for failed forwarders.
The redirect timer interval in the range from 0 to 3600
seconds. The default is 600 seconds (10 minutes).
The zero value for the
Note
time-interval-to-redirect argument cannot be
removed from the range of acceptable values
because preexisting configurations of Cisco
IOS software already using the zero value
could be negatively affected during an
upgrade. However, be advised that a zero
setting is not recommended
andtime-interval-to-redirect, if used, results
in a redirect timer that never expires. If the
redirect timer does not expire, then when a
device fails, new hosts continue to be
assigned to the failed device instead of being
redirected to the backup.
