Description
In addition to an ID assignment, a virtual router configuration can be assigned a textual description
(up to 64 characters) to further distinguish it from others with a similar configuration.
Priority
Use the spinner control to set a VRRP priority setting from 1 - 254. The access point uses the
defined setting as criteria in selection of a virtual router master. The higher the value, the greater
the likelihood of this virtual router ID being selected as the master.
Virtual IP Addresses
Provide up to 8 IP addresses representing the Ethernet switches, routers or security appliances
defined as virtual router resources to the Brocade Mobility 7131 Access Point access point.
Advertisement Interval
Unit
Select either seconds, milliseconds or centiseconds as the unit used to define VRRP
advertisements. Once an option is selected, the spinner control becomes enabled for that
Advertisement Interval option. The default interval unit is seconds. If changing the VRRP group
version from 2 to 3, ensure the advertisement interval is in centiseconds. Use VRRP group version
2 when the advertisement interval is either in seconds or milliseconds.
Advertisement Interval
Once the Advertisement Interval Unit has been selected, use the spinner control to set the interval
at which the VRRP master sends out advertisements on each of its configured VLANs. The default
setting is 1 second.
Preempt
Select this option to ensure a high priority backup router is available to preempt a lower priority
backup router resource. The default setting is enabled. When selected, the Preempt Delay option
becomes enabled to set the actual delay interval for pre-emption. This setting determines if a node
with a higher priority can takeover all the Virtual IPs from the nodes with a lower priority.
Preempt Delay
If the Preempt option is selected, use the spinner control to set the delay interval (in seconds) for
preemption.
Interface
Select this value to enable/disable VRRP operation and define the Brocade Mobility 7131 Access
Point VLAN
(1 - 4,094) interface where VRRP will be running. These are the interfaces monitored to detect a
link failure.
Sync Group
Select this option to assign a VRRP sync group to this VRRP ID’s group of virtual IP addresses. This
triggers VRRP failover if an advertisement is not received from the virtual masters that are part of
this VRRP sync group. This setting is disabled by default.
Network Monitoring: Local
Interface
Select wwan1, pppoe1 and VLAN ID(s) as needed to extend VRRP monitoring to these local access
point interfaces. Once selected, these interfaces can be assigned an increasing or decreasing level
or priority for virtual routing within the VRRP group.
Network Monitoring:
Critical Resources
Assign the priority level for the selected local interfaces. Backup virtual routers can increase or
decrease their priority in case the critical resources connected to the master router fail, and then
transition to the master state themselves. Additionally, the master virtual router can lower its
priority if the critical resources connected to it fails, so the backup can transition to the master
state. This value can only be set on the backup or master router resource, not both. Options include
None, increment-priority, and decrement priority.
Network Monitoring: Delta
Priority
Use this setting to decrement the configured priority (by the set value) when the monitored
interface is down. When critical resource monitoring, the configured value is incremented by the
value defined.
