Configuring the UDS Using Telnet or the Serial Port UDS10/UDS100 User Guide
36
TCP Keepalive time in s
This option defines how many seconds the unit waits during a silent connection
before checking to see whether the currently connected network device is still on the
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
over the serial setup. If you set security over the network (Telnet 9999),
someone else could capture these settings.
Caution: Disabling both Telnet Setup and Port 77FE prevents users
from accessing the Setup Mode from the network.
Figure 5-8. Security Settings
Disable SNMP
This setting disables the SNMP protocol on the unit to prevent SNMP management
software from communicating with the UDS.
