ARP Flooding in HP A5500-24G-SFP EI Switch with 2 Interface

Hi All..

 

I just install new HP A5500-24G-SFP EI Switch to replace old 3 com switch - 

Switch 5500G-EI SFP 24 Port ( 24Port SFP Slot) 

 

Configuration in 2 Vlan - So far running but in log file new switch, we have a lot off warning :

26:44:446 2014 HP5500 ARP/4/RATELIMIT: The ARP packet rate(60pps) exceeded the rate limit(50pps) on interface GigabitEthernet1/0/5 in the last 60 seconds.
%Jan 6 11:29:44:249 2014 HP5500 ARP/4/RATELIMIT: The ARP packet rate(60pps) exceeded the rate limit(50pps) on interface GigabitEthernet1/0/5 in the last 60 seconds.
%Jan 6 11:31:44:451 2014 HP5500 ARP/4/RATELIMIT: The ARP packet rate(64pps) exceeded the rate limit(50pps)

 

For your information, all LAN client IP address we are set as static IP dont and dont we have DHCP server..

If we are issue command display all arp have a lot off IP that we are not allocate such like DHCP server generated IP.

Hi Zack,

We've been having a discussion about this at http://h30499.www3.hp.com/t5/Comware-Based/The-ARP-packet-rate-89pps-exceeded-the-rate-limit-50pps-on/td-p/6232585

Not much progress to report, though - see my recent update.
Regards,
Paul
