ARP cache entries for which there has been no traffic timeout in several minutes. However, I have not found any documentation for Linux (e.g. arp(7)) on what the value for this timeout is and whether it is configurable. All the timeouts in the documentation appear to be in the region of seconds rather than minutes that I'd expect in this case Can somebody tell me how to determine this timeout.
