I am using arp-timeout 900 (means 15min), because of having problems with my upstream ethernet connection and everything is ok, and I have not seen any relation between MAC Address aging time and that, aging time is default 300sec for me ;) Thanks On Fri, Aug 10, 2012 at 6:53 PM, Jay Nakamura <zeusdadog () gmail com> wrote:
Cisco default ARP timeout is 4 hours. Do anyone change that to something shorter in a provider environment for customer with Ethernet connectivity? What is a good value to set it to? Are there any impacts for lowering the timeout? Other than higher CPU util for doing ARP a lot more on the router?
