Installation and Basic Configuration Guide
timer values enables you to easily change all the timers while preserving the ratios among their values. Here is an
example.
Timer
Hello interval
Dead interval
Backup Hello interval
Hold-down interval
If you configure the device to receive its timer values from the Master, the Backup also receives the timer scale
value from the Master.
NOTE: The Backups always use the value of the timer scale received from the Master, regardless of whether the
timer values that are saved in the configuration are the values configured on the Backup or the values received
from the Master.
To change the timer scale, enter a command such as the following at the global CONFIG level of the CLI:
HP9300(config)# scale-timer 2
This command changes the scale to 2. All VSRP timer values will be divided by 2.
Syntax: [no] scale-timer <num>
The <num> parameter specifies the multiplier. You can specify a timer scale from 1 – 10.
Configuring Authentication
If the interfaces on which you configure the VRID use authentication, the VSRP packets on those interfaces also
must use the same authentication. VSRP supports the following authentication types:
• No authentication – The interfaces do not use authentication. This is the default.
• Simple – The interfaces use a simple text-string as a password in packets sent on the interface. If the
interfaces use simple password authentication, the VRID configured on the interfaces must use the same
authentication type and the same password.
To configure a simple password, enter a command such as the following at the interface configuration level:
HP9300(config-if-1/6)# ip vsrp auth-type simple-text-auth ourpword
This command configures the simple text password "ourpword".
Syntax: [no] ip vsrp auth-type no-auth | simple-text-auth <auth-data>
The auth-type no-auth parameter indicates that the VRID and the interface it is configured on do not use
authentication.
The auth-type simple-text-auth <auth-data> parameter indicates that the VRID and the interface it is configured
on use a simple text password for authentication. The <auth-data> value is the password. If you use this
parameter, make sure all interfaces on all the devices supporting this VRID are configured for simple password
authentication and use the same password.
