Changing the Dead interval
The Dead interval is the number of seconds a Backup waits for a Hello message from the Master
before determining that the Master is dead.
To change the Dead interval, enter a command such as the following at the configuration level for
the VRID.
Brocade(config-vlan-200-vrid-1)# dead-interval 3
Syntax: [no] dead-interval num
The num parameter specifies the interval and can be from 3 – 84 units of 100 milliseconds. The
default is 3 units of 100 ms (300 milliseconds).
NOTE
If you change the timer scale, the change affects the actual number of seconds.
Changing the Backup Hello state and interval
By default, Backups do not send Hello messages to advertise themselves to the Master. You can
enable these messages if desired and also change the message interval.
To enable a Backup to send Hello messages to the Master, enter a command such as the following
at the configuration level for the VRID.
Brocade(config-vlan-200-vrid-1)# advertise backup
Syntax: [no] advertise backup
When a Backup is enabled to send Hello messages, the Backup sends a Hello message to the
Master. The interval be from 600 – 3600 units of 100 milliseconds. The default is 600 units of 100
milliseconds.
To change the Backup Hello interval, enter a command such as the following at the configuration
level for the VRID.
Brocade(config-vlan-200-vrid-1)# backup-hello-interval 180
Syntax: [no] backup-hello-interval num
The num parameter specifies the message interval and can be from 600 – 3600 units of 100
milliseconds. The default is 600 units of 100 milliseconds.
NOTE
If you change the timer scale, the change affects the actual number of seconds.
Changing the hold-down interval
The hold-down interval prevents Layer 2 loops from occurring during failover, by delaying the new
Master from forwarding traffic long enough to ensure that the failed Master is really unavailable.
To change the hold-down interval, enter a command such as the following at the configuration level
for the VRID.
Brocade(config-vlan-200-vrid-1)# hold-down-interval 4
Syntax: [no] hold-down-interval num
