Virtual Switch Redundancy Protocol (VSRP)
10
To change the timer scale, enter a command such as the following at the global CONFIG level of the
CLI.
PowerConnect(config)# scale-timer 2
This command changes the scale to 2. All VSRP, VRRP, and VRRP-E 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.
PowerConnect(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.
Configuring security features on a VSRP-aware device
This section shows how to configure security features on a VSRP-aware device. For an overview of
this feature, refer to “VSRP-Aware security features” on page 364.
Specifying an authentication string for VSRP hello packets
The following configuration defines pri-key as the authentication string for accepting incoming
VSRP hello packets. In this example, the VSRP-aware device will accept all incoming packets that
have this authorization string.
PowerConnect(config)#vlan 10
PowerConnect(config-vlan-10)#vsrp-aware vrid 3 simple-text-auth pri-key
Syntax: vsrp-aware vrid <vrid number> simple text auth <string>
