network. If the unit does not receive a response, it drops that connection.

ARP Cache timeout in s

When the unit communicates with another device on the network, it adds an entry
into its ARP table. The ARP Cache timeout option defines the number of seconds
(1-600) the unit waits before timing out an entry in this table.

Security Settings

Change these settings using Telnet or serial connections only, not Web Manager.
Note: We recommend that you set security over the dedicated network or
