The WAN Port Software Menu
Page 28-20
Loopback Timeout
Sets the transition time between proprietary messages sent over the link. These messages are
analyzed to determine whether the link is in a loopback state. This only displays if the port is
using Frame Relay as its encapsulation type. The valid range is 0-255.
Connection Function
On serial ports using PPP, it is possible to configure the port to be a DTR dial backup port. In
case the primary WAN port fails, a DTR dial backup port will use a synchronous modem to
dial out and reestablish the WAN connection. If this feature is disabled, the Connection
Function field will read Dedicated. If it is enabled, the field will read DTR-Dial, and the
following options will also be displayed:
200) Connect Timeout (seconds) ............................ 60
201) Retry Delay (seconds) .................................... 10
Connect Timeout
The number of seconds the switch attempts to establish a connection via this port before
declaring the attempt a failure. The valid range is 10 to 2147483647. The default is 60. If
the value is entered as 0, the attempt will never timeout.
Retry Delay
The number of seconds after a connection failure the switch waits before attempting a
new connection. The valid range is 1 to 2147483647. The default is 1.
