VSRP
If VSRP hello packets do not meet the acceptance criteria, the VSRP-aware device forwards the
packets normally, without any VSRP-aware security processing.
To configure VSRP-Aware Security features, refer to “Configuring security features on a VSRP-aware
device” on page 645.
VSRP parameters
Table 118 lists the VSRP parameters.
TABLE 118 VSRP parameters
Parameter Description Default For more
information
Protocol VSRP state
NOTE: On a Layer 3 Switch, you must disable VSRP to
use VRRP-E or VRRP.
Enabled page 643
Virtual Router ID
(VRID)
The ID of the virtual switch you are creating by
configuring multiple devices as redundant links. You
must configure the same VRID on each device that
you want to use to back up the links.
None page 642
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 page 644
VSRP-Aware Security Parameters
VSRP-Aware
Authentication
type
The type of authentication the VSRP-aware devices
will use on a VSRP backup switch:
• No authentication – The device does not accept
incoming packets that have authentication
strings.
• Simple – The device uses a simple text-string as
the authentication string for accepting incoming
packets.
Not configured page 645
VRID parameters
VSRP device
type
Whether the device is a VSRP Backup for the VRID.
All VSRP devices for a given VRID are Backups.
