Setting VRRP Traps
A VRRP router has the capability to generate VRRP SNMP traps for events defined in the VRRP SNMP 
MIB. By default traps are enabled.
In order for VRRP traps to be generated correctly, traps in general must be enabled on the switch through 
the SNMP CLI. See the OmniSwitch AOS Release 6 Switch Management Guide for more information 
about enabling SNMP traps globally.
To disable VRRP traps, use the no form of the 
-> no vrrp trap
To re-enable traps, enter the vrrp trap command.
-> vrrp trap
Setting VRRP Startup Delay
After a switch reboot, the delay which is a global value takes effect and all virtual routers remain in the 
initialize
 
state. They will remain in this state until the timer expires, at which point they will negotiate to 
determine whether to become the master or a backup.
To set a delay to all the virtual routers from going active before their routing tables are set up, use th
 command. This command applies only when the switch reboots.
-> vrrp delay 75
The switch now waits 75 seconds after its reboot before it becomes available to take over as master for 
another router.
Note. This command applies only when the switch reboots.
Configuring Collective Management Functionality
Collective management simplifies the management and configuration tasks of either all the virtual routers 
on the switch or only the virtual routers in a particular virtual router group.
The following section describes the above mentioned collective management functionality in detail:
Changing Default Parameter Values for all Virtual Routers
You can change the default advertising interval value of all the virtual routers on a switch using the 
 command. For example:
-> vrrp interval 50 
You can change the default priority value of all the virtual routers on a switch using th
command. For example:
-> vrrp priority 50 
You can change the default preempt mode of all the virtual routers on a switch using the 
 
command. For example:
