Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 618)

To change the Master priority, enter commands such as the following.
device(config)# interface ethernet 1/6
device(config-if-1/6)# ip vrrp vrid 1
device(config-if-1/6-vrid-1)# owner priority 99
Syntax: [no] owner priority num
The num variable specifies the new priority and can be a number from 1 through 254.
When the command is enabled, the software changes the priority of the Master to the specified
priority. If the new priority is lower than at least one Backup priority for the same VRID, the Backup
router takes over and becomes the new Master until the next software reload or system reset.
To verify the change, enter the following command from any level of the CLI.
device#show ip vrrp
Total number of VRRP routers defined: 1
Interface ethernet v3
auth-type simple text password
VRID 3
state backup
administrative-status enabled
version v3
mode non-owner(backup)
priority 110
current priority 110
hello-interval 1000 msec
dead-interval 0 msec
current dead-interval 3500 msec
preempt-mode true
ip-address 172.21.3.1
virtual mac address 0000-5E00-0103
advertise backup: enabled
next hello sent in 00:00:26.1
master router 172.21.3.1 expires in 00:00:02.7
track-port 4/1-4/4(up)
This example shows that even though this Layer 3 switch is the Owner of the VRID ("mode owner"),
the Layer 3 switch priority for the VRID is 110 and the state is now "backup" instead of "active". In
addition, the administrative status is "enabled".
To change the Master priority back to the default Owner priority 255, enter no followed by the
command you entered to change the priority. For example, to change the priority of a VRRP Owner
back to 255 from 110, enter the following command.
device(config-if-1/6-vrid-1)#no owner priority 110
You cannot set the priority to 255 using the owner priority command.
Displaying VRRP and VRRP-E information
You can display the following information for VRRP or VRRP-E:
• Summary configuration and status information
• Detailed configuration and status information
• VRRP and VRRP-E statistics
Syntax for IPv4 and IPv6 VRRP:
Syntax: show ip vrrp [ brief | [ stat | [ statistics ] [ vrid num ] ] [ ethernet stack/slotnum/portnum | ve
num ] ]
