Interface tab items


Field Description
VrId
A number that uniquely identifies a virtual router on a given VRRP router. The virtual router acts as the default router for one or more assigned addresses (1 to 255).
Interface
The port interface index.
IpAddr
The assigned IP addresses that a virtual router is responsible for backing up.
VirtualMacAddr
MAC address of the virtual router interface.
State
The state of the virtual router interface:
  • initialize--waiting for a startup event
  • backup--monitoring availability and state of the dominant router
  • master--functioning as the forwarding router for the virtual router IP address(es)
Control
Whether VRRP is enabled or disabled for the port or VLAN.
Priority
Priority value to be used by this VRRP router. Set a value from 1 to 255, where 255 is reserved for the router that owns the IP addresses associated with the virtual router. The default is 100.
MasterIpAddr
The IP address of the physical interface of the dominant virtual router that has the responsibility of forwarding packets sent to the virtual IP address(es) associated with the virtual router.
AdvertisementInterval
The time interval (in seconds) between sending advertisement messages. Set from 1 to 255 seconds with a default of 1 second. Only the dominant router sends advertisements.
VirtualRouterUpTime
The time interval (in hundredths of a second) since the virtual router was initialized.
CriticalIPAddrEnable
Indicate if a user-defined critical IP address should be enabled. No = use the default IP address (0.0.0.0).
CriticalIPAddr
An IP interface on the local router configured so that a change in its state would cause a role switch in the virtual router (for example, from dominant to subordinate) in case the interface stops responding.
HoldDownTimer
The time interval (in seconds) a router is delayed when changing to dominant state.
HoldDownState
Status is active when the Hold Down Timer is counting down and preemption occurs; the text box displays dormant when preemption is not pending.
HoldDownTimeRemaining
The seconds remaining before preemption.
OperAction
Use the action list to manually override the delay timer and force preemption:
  • preemption--preempt the timer
  • none--allow the timer to keep working

  1. Click the HoldDownTimer test box, and enter the desired number of seconds for the timer (0 to 21600 seconds).
    2. The HoldDown Timer delays preemption. The default value is 0 seconds. The HoldDownState text box displays active when the Hold Down Timer is counting down and preemption occurs; the text box displays dormant when preemption is not pending. When the Hold Down Timer is active, the HoldDownTimeRemaining text box displays the seconds remaining before preemption.
    Use the Action text box to manually override the delay timer and to force preemption. When you click the heading, an arrow appears. Click the text box, and a list opens. Choose preemption to preempt the timer, or choose none to allow the timer to keep working.
    Nortel Networks recommends that you set all your routers to the identical number of seconds for the HoldDown Timer.
  2. Click Apply.
