Hi,

We have a router (7206) which connected to client device in /30 IP segment, but this device is a switch which connected to many more devices.

Doing packet capture on our router interface unravel many ARP requests whcih comes from the client switch.

Is there any feature or command which we can stop this?

Thanks ahead.

Hi,

If you want to limit arp request on switch you may go through below link.

http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/port_sec.html

It helps you to configure maximum number of mac-address per physical port.

Just for more insight Can you show topology for one customer. Is it like 7206-----Trunk----Switch----Customers ?
