Usage Guidelines
Usage Scenario
After ND protocol packet validity check is enabled using the nd snooping check enable command, the device checks the NA, NS, and RS packets received from untrusted interfaces against the ND snooping binding table and discards the packets that do not match the binding table. If the number of discarded packets exceeds the threshold, the corresponding alarm is generated. The minimum interval for sending alarm messages is 1 minute. You can run the nd snooping alarm binding-table check threshold command to set the alarm threshold.
Prerequisites
ND snooping has been enabled on the device using the nd snooping enable command.
Precautions
To ensure that alarms can be properly reported, you need to run the snmp-agent trap enable feature-name dhcp command to enable the DHCP module to report the corresponding alarm. You can check whether the DHCP module is enabled to report the corresponding alarm using the display snmp-agent trap feature-name dhcp all command.
