Usage Scenario

After the alarm function of DHCPv6 messages discarded is enabled using the dhcpv6 packet-rate drop-alarm enable command, the device records alarm information when the number of DHCPv6 packets that are discarded exceeds the alarm threshold.

Prerequisites

The DHCP function has been enabled globally using the dhcp enable command.
The DHCPv6 packet rate limit has been enabled using the dhcpv6 packet-rate packet-rate command.
The alarm function for discarding DHCPv6 messages when the rate of DHCPv6 messages exceeds the limit has been enabled using the dhcpv6 packet-rate drop-alarm enable command.

Example

# Configure the device to generate an alarm when the number of DHCPv6 messages discarded exceeds 150 packets.
