msg on 6513 Switch arp: ether address is broadcast for ip...

I have an urgent issue. We notice that we can't ping our company's core switch Catalyst 6513 and i logged in and saw high broadcast traffic from PCs on a subnet configured as a secondary ip address on the default head office vlan. I remove the secondary subnet ip and the high broadcast traffic reduce. But i now get a log on the console that says: arp: ether address is broadcast for IP address a000468! I dont understand this message. Please help urgently. Thnks.

Hi,please check arp manual to understand this error.

arp: ether address is broadcast for IP address %d.%d.%d.%d!: ARP requested information for a host, and received an answer indicating that the host's ethernet address is the ethernet broadcast address. This indicates a misconfigured or broken device.

Hope this clarifies.

Hi, can you please check the arp entry for 10.0.64.104 in your 6k.Also please check if you have a mac entry in the cam table.this may give a clue.

Thanks Nambi... the log message has stopped after a while and without me doing anything. I still checked the arp table. But I didn't see any entry for 10.0.64.104. Actually we don't have 10.0.64.0 subnet on our network. Is that what the a000468! works out to? Please how did you work out the ip address 10.0.64.104? Thanks a million.

Hi,if you convert a000468 to decimal you will get the IP address 10.0.64.104.
