Timer scale

The value used by the software to calculate all
VSRP timers. Increasing the timer scale value
decreases the length of all the VSRP timers
equally, without changing the ratio of one timer to
another.

Interface parameters

Authentication
type

The type of authentication the VSRP devices use
to validate VSRP packets. On Layer 3 Switches,
the authentication type must match the
authentication type the VRID port uses with other
routing protocols such as OSPF.

• No authentication - The interfaces do not use

authentication.

• Simple - The interface uses a simple text-string

as a password in packets sent on the interface.
If the interface uses simple password
authentication, the VRID configured on the
interface must use the same authentication
type and the same password.

NOTE
MD5 is not supported.

• No authentication - The device does not accept

incoming packets that have authentication
strings.

• Simple - The device uses a simple text-string

incoming packets.
