Netstat ARP/-R

Use the command Netstat ARP/-R to query the ARP cache for a given address. Use Netstat ARP/-R ALL to query an entire ARP cache table. Ensure Netstat ARP/-R displays an ARP entry for the remote hosts.

The ARP entry for the host on a remote network contains the IP address and the MAC address for the router.

To ensure the host has a route back to the z/OS® Communications Server, review the routing tables on the remote host. The route back can be a host route or network route. Intermediate routers must also be configured correctly.
