The ARP Table Utilities page is activated from the Protocol page.
The ARP Table Utilities page allows the user to view and edit the ARP table defined by
the CiM. It allows up to 1024 static ARP entries. The Static ARP entries provided by the
CiM fall into two categories: IP->MAC and IP->HDLC.
Note For the CiM to properly route packets over the Satellite Interface, all of the Next Hop
Addresses in the route table MUST have an IP to HDLC mapping in the ARP table. If the
destination IP address of an incoming packets matches a route in the route table that does not
have an IP to HDLC mapping, it will be silently discarded.
The ARP Table Utilities page contains the following options/fields:
