Enabling The Trap Function For Vrrp - HP A5830 series Configuration Manual

To do...
• Enter the specified interface
view
•
Configure the authentication
mode and authentication key
when the VRRP groups send
and receive VRRP packets
• Configure the time interval for
the master in the VRRP group
to send VRRP advertisements
• Disable TTL check on VRRP
packets
You might configure different authentication modes and authentication keys for the VRRP groups on an
interface. However, the members of the same VRRP group must use the same authentication mode and
authentication key.
Excessive traffic might cause a backup to trigger a change of its status because the backup does not
receive any VRRP advertisements for a specified period of time. To solve this problem, prolong the time
interval to send VRRP advertisements.
Configuring different intervals for sending VRRP advertisements on the routers in a VRRP group might
cause a backup to trigger a change of its status because the backup does not receive any VRRP
advertisements for a specified period of time. To solve this problem, configure the same interval for
sending VRRP advertisements on each router in the VRRP group.

Enabling the trap function for VRRP

When the trap function is enabled for VRRP, VRRP generates traps with severity level errors to report its
key events. The traps are sent to the information center of the device, where you can configure whether
to output the trap information and the output destination. For how to configure the information center,
see Network Management and Monitoring Configuration Guide.
