Description
Specify the ARP cache next-hop limit at the system (global) level to restrict the number of next-hop routes. To configure the limit at the interface level, use the arp-max-cache statement.
Default
The default behavior of ARP is to remove the cache entry if it is not used within a certain period of time, and not to allow the cache to grow too large. You can also manage the number of ARP cache next-hop entries by configuring a limit to the maximum number of next hops that can be created.
Options
| number | Indicates the maximum number of routes to be held in the ARP cache. |
Range: 1 through 2,000,000

(EX4200, EX4300, EX4500, EX4550, and EX6210 switches, MX Series routers) 75,000
