VSRP parameters (Continued)TABLE 21
Parameter Description Default For more
information
Backup Hello state
and interval
The amount of time between Hello messages
from a Backup to the Master.
The message interval can be from 60 - 3600
seconds.
You must enable the Backup to send the
messages. The messages are disabled by default
on Backups. The current Master sends Hello
messages by default.

Hold-down interval The amount of time a Backup that has sent a
Hello packet announcing its intent to become
Master waits before beginning to forward traffic for
the VRID. The hold-down interval prevents Layer
2 loops from occurring during VSRP rapid failover.
The interval can from 1 - 84 seconds.
3 seconds Changing the hold-
down interval setting

Track priority A VSRP priority value assigned to the tracked
ports. If a tracked port link goes down, the VRID
port VSRP priority is reduced by the amount of the
tracked port priority.

track priority setting

Track port A track port is a port or virtual routing interface
that is outside the VRID but whose link state is
tracked by the VRID. Typically, the tracked
interface represents the other side of VRID traffic
flow through the device.
If the link for a tracked interface goes down, the
VSRP priority of the VRID interface is changed,
causing the devices to renegotiate for Master.

Backup preempt
mode
Prevents a Backup with a higher VSRP priority
from taking control of the VRID from another
Backup that has a lower priority but has already
assumed control of the VRID.
Enabled Disabling or re-
enabling backup pre-

VRID active state The active state of the VSRP VRID. Disabled Configuring basic

RIP parameters
Suppression of
RIP
advertisements
A Layer 3 Switch that is running RIP normally
advertises routes to a backed up VRID even when
the Layer 3 Switch is not currently the active
Layer 3 Switch for the VRID. Suppression of these
advertisements helps ensure that other Layer 3
Switches do not receive invalid route paths for the
VRID.
NOTE
This parameter is valid only on Layer 3 Switches.
Disabled

advertised)
