Dell Command Line Reference Guide for the S4048–ON System 9.14.2.6
track reachability refresh
Change the refresh interval for tracking the reachability of the next-hop. If the next-hop address in the ARP cache ages out for a route tracked for its reachability, an attempt is made to check if the next-hop address is reachable after a certain refresh interval before considering the route DOWN.
- Syntax
- track reachability refresh interval
- Parameters
- interval
- Enter the refresh interval, in seconds, for object tracking reachability. The range is from 0 to 60 seconds. The default is 60.
