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.
