Hi All
Please help me, I am using two A5500 switches in stack with ios version 5.20.99, Release 5206.
I am getting below errors continuously in my network due to this my network performance has been very slow. I mean i getting high latency in my network. I tried to resolve this issue. But m not getting any solution how to over come to this problem.
As this is very large network. I am unable to find the solutions.
%May 23 22:09:30:548 2000 SHPK_OCC_CORE ARP/5/ARP_DUPLICATE_IPADDR_DETECT: Detected an IP address conflict. The device with MAC address 448a-5b54-bc12 connected to GigabitEthernet1/0/26 in VLAN 2 and the device with MAC address 5065-f343-6bfc connected to GigabitEthernet1/0/26 in VLAN 2 are using the same IP address 10.27.2.90.
%May 23 22:09:43:124 2000 SHPK_OCC_CORE MSTP/6/MSTP_DETECTED_TC: Instance 0's port GigabitEthernet1/0/3 detected a topology change.
%May 23 22:09:55:312 2000 SHPK_OCC_CORE ARP/4/RATELIMIT: The ARP packet rate(468pps) exceeded the rate limit(100pps) on interface GigabitEthernet1/0/26 in the last 60 seconds.

Re: HP 5120 ARP Issue
The log line says it all:
"Detected an IP address conflict. The device with MAC address 448a-5b54-bc12 connected to GigabitEthernet1/0/26 in VLAN 2 and the device with MAC address 5065-f343-6bfc connected to GigabitEthernet1/0/26 in VLAN 2 are using the same IP address 10.27.2.90"
Fix it!
The log message is telling you exactly what the switch is seeing...so the only thing you must do is discover, among your devices connected on VLAN2, who owns the reported MAC Addresses (a Micro-Star NIC and a HP NIC as per MAC Addresses lookup available in Internet)...those two devices are uncorrectly using the same IP Address (10.27.2.90) and so they are creating an IP Address conflict!
Solve that first!
Since the physical port on which these two MAC Addresses (devices) are being saw by the Switch/Stack is the same (the GigaEthernet1/0/26) this make me think that probably you have another switch (or a Wireless AP?) connected to that physical port.
