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. To enable the trap function for VRRP: Step 1. Enter system view. 2. Enable the trap function for VRRP. Command system-view snmp-agent trap enable vrrp [ authfailure | newmaster ] Remarks N/A Optional. Enabled by default.

Configuration prerequisites
Before you configure the relevant attributes of VRRP packets, create a VRRP group and configure a virtual
IP address for it.
Configuration procedure
To configure VRRP packet attributes:
Step
Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Set the Differentiated Services
Code Point (DSCP) value for
VRRP packets.
vrrp dscp
dscp-value
Optional.
48 by default.
3.
Enter the specified interface
view.
interface
interface-type
interface-number
N/A
4.
Configure the authentication
mode and authentication key
when the VRRP groups send
and receive VRRP packets.
vrrp vrid
virtual-router-id
authentication-mode
{
md5
|
simple
} [
cipher
]
key
Optional.
Authentication is not performed by
default.
5.
Configure the time interval for
the master in the VRRP group
to send VRRP advertisements.
vrrp vrid
virtual-router-id
timer
advertise
adver-interval
Optional.
1 second by default.
6.
Disable TTL check on VRRP
packets.
vrrp un-check ttl
Optional.
Enabled by default.
You do not need to create a VRRP
group before executing this
command.
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
.
To enable the trap function for VRRP:
Step
Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enable the trap function for
VRRP.
snmp-agent trap enable vrrp
[
authfailure
|
newmaster
]
Optional.
Enabled by default.
For more information about the
snmp-agent trap enable vrrp
command, see the
snmp-agent trap enable
command in
