Cisco Nexus 3548 Switch NX-OS Unicast Routing Command Reference
OL-27852-01
Chapter Unicast Routing Commands
hsrp delay
hsrp delay
To delay Hot Standby Router Protocol (HSRP) initialization after a reload or after an interface comes
up, use the hsrp delay command. To disable this function, use the no form of this command.
hsrp delay {minimum min-delay | reload reload-delay}
no delay {minimum min-delay | reload reload-delay}
Syntax Description
Command Default The HSRP delay default is 0 seconds.
Command Modes Interface configuration mode
Command History
Usage Guidelines The HSRP delayed initialization configuration allows the interface and router to stabilize after the
interface comes up and helps prevent HSRP state flapping.
This command does not require a license.
Examples This example shows how to configure a minimum delay of 3 seconds and a group initialization delay of
10 seconds:
switch# configure terminal
switch(config)# interface ethernet 1/5
switch(config-if)# no switchport
switch(config-if)# ip address 192.168.0.5 255.255.255.0
switch(config-if)# hsrp 1
switch(config-if)# hsrp delay minimum 3 reload 10
switch(config-if)#
Related Commands
minimum min-delay Minimum time (in seconds) to delay HSRP group initialization after an
interface comes up. This period applies to all subsequent interface events.
The range is from 1 to 10,000. The default is 0 seconds.
reload reload-delay Time period to delay HSRP group initialization after the router has
reloaded. This period applies only to the first interface-up event after the
router has reloaded. The range is from 1 to 10,000. The default is 0 seconds.
Release Modification
5.0(3)A1(1) This command was introduced.
Command Description
feature hsrp Enables the HSRP configuration.
