In this example, virtual router 7 on VLAN 3 is disabled. The virtual router is then modified to change its
priority setting. (For information about configuring the priority setting, see
.) The virtual router is then re-enabled and will be active on the switch.
Setting VRRP Traps
A VRRP router has the capability to generate VRRP SNMP traps for events defined in the VRRP SNMP
MIB.
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 7 Switch Management Guide
for more information
about enabling SNMP traps globally.
To disable VRRP traps, use the
no
form of the
command.
-> 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 the
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 the
command. For example:
