Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 597)

VRRP and VRRP-E parameters (Continued) TABLE 125
Parameter Description Default
Dead interval The number of seconds or milliseconds a Backup waits for a Hello
message from the Master for the VRID before determining that the
Master is no longer active.
If the Master does not send a Hello message before the dead
interval expires, the Backups negotiate (compare priorities) to select
a new Master for the VRID.
The dead interval
calculation for VRRP v6
or VRRP-E v6 is:
Dead Interval: ( 3 X
Hello Interval ) + Skew
Time
Skew Time is 256 -
Priority X Hello Interval /
256.
For VRRP v3, the
default is 3600
milliseconds. The
configurable range is
from 100 through 8400
milliseconds. For
VRRP-E v3, the default
is 3600 milliseconds.
The configurable range
is from 1 through 84
seconds.
Backup Hello
interval The number of seconds between Hello messages from a Backup to
the Master.
The message interval can be from 60 through 3600 seconds.
You must enable the Advertise backup to send the messages. The
messages are disabled by default on Backups. The current Master
(whether the VRRP Owner or a Backup) sends Hello messages by
default.
Disabled
60 seconds when
enabled
Track port Another Layer 3 switch port or virtual interface whose link status is
tracked by the VRID interface.
If the link for a tracked interface goes down, the VRRP or VRRP-E
priority of the VRID interface is changed, causing the devices to
renegotiate for the Master.
NOTE
Track port is not supported by VRRP v3.
None
Track priority A VRRP or VRRP-E priority value assigned to the tracked ports. If a
tracked port link goes down, the VRID port VRRP or VRRP-E
priority changes:
• VRRP - The priority changes to the value of the tracked port
priority.
• VRRP-E - The VRID port priority is reduced by the amount of the
tracked port priority.
NOTE
Track priority is not supported by VRRP v3.
VRRP - 2
VRRP-E - 5
