[Praveen_Myalil]

Hi, 

I am getting a opsramp alert from Comware switch as: HH3C-ARP-RATELIMIT-MIB::hh3cARPRatelimitOverspeedTrap (1.3.6.1.4.1.25506.2.110.1.1.0.1) - If the rate of ARP packets delivered to the CPU on a device exceeds the threshold, a trap message is generated and sent to the remote monitoring device..

DEVICE_NAME : 5900AF-48G-4XG-2QSFP+ JG510A

The switch is in an IRF pair, and connecting to few of the Servers and gateway switches.  From display logbuffer reverse | in arp  Couldnt fetch any logs related to Arp. 

Kindly provide your suggestions

Hi @Praveen_Myalil !

This trap means one or more Vlan-interfaces of the switch receive ARP messages which number exceeds the limit defined. Check the switch configuration for any "arp rate-limit" commands configured under Layer 2 or BAGG interfaces. If you want to get log messages in the buffer for ARP limit exceed events, use "arp rate-limit log enable" global command. If you don't want to get such traps on your NMS, try "undo snmp-agent trap enable arp rate-limit" to stop these traps.
