Notification triggers

This notification is generated when the number of ND entries learned by the device exceeds the alarm threshold (80% of the upper entry limit).

System impact

The device might not learn new ND entries, which causes service interruption.

Recommended action

1.Execute the display ipv6 neighbors all command to compare the numbers of static and dynamic ND entries.

- If the number of static ND entries is larger, go to step 2.

- If the number of dynamic ND entries is larger, go to step 3.

2.Based on the network planning and service deployment, check whether the static ND entries are necessary.

- If the static ND entries are necessary, go to step 4.

- If the static ND entries are not necessary, execute the undo ipv6 neighbor command to delete specified ND entries or execute the reset ipv6 neighbors static command to clear all static ND entries. Make sure the operation does not affect services.

3.Execute the ipv6 neighbors max-learning-number command to set a larger dynamic ND learning limit for the device. Execute the ipv6 neighbors max-learning-num command to set larger dynamic ND learning limits for interfaces.

4.If the issue persists, collect configuration files and alarm information, and then contact Technical Support for help.

Recommended action

1.Execute the display ipv6 nd suppression xconnect-group command to view ND suppression entries.

2.Based on the network planning and service deployment, check whether the ND suppression entries are necessary.

- If the ND suppression entries are necessary, go to step 3.

- If the ND suppression entries are not necessary, execute the reset ipv6 nd suppression xconnect-group command to clear ND suppression entries.

3.If the issue persists, collect configuration files and alarm information, and then contact Technical Support for help.

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.2.218.2.0.1	The sending rate pf ND packets or ND Miss messages exceeded the alarm threshold.	Error	Warning	1.3.6.1.4.1.25506.2.218.2.0.2 (hh3cNDTrapPktSpeedAlarmResume)	OFF

Notification triggers

This notification is generated when the sending rate of ND packets triggered by services or ND Miss messages exceeds the alarm threshold (80% of the upper rate limit). When the device receives an IP packet with an unresolvable destination IP address, it sends a ND Miss message to the CPU.

System impact

The device might not send ND requests normally, which affects ND learning. As a result, traffic cannot be forwarded.

Status control

CLI: Use the snmp-agent trap enable nd nd-miss command.

OFF

CLI: Use the undo snmp-agent trap enable nd nd-miss command.

Recommended action

1.Capture packets to identify and analyze the source of IPv6 packets that trigger ND resolution. If the source is unreasonable, limit attack packet sending for the attack source.

2.If the issue persists, collect configuration files and alarm information, and then contact Technical Support for help.
