Advanced PPP parameters
This section contains PPP configuration parameters that do not normally need changing from the
defaults and are therefore placed in a separate section to reduce clutter on the web pages.
Metric
The connected metric of the interface. The default metric of a connected interface is 1 . By
allowing the interface to have a higher value (lower priority), static routes can take precedence
over interfaces. For normal operation, leave this setting unchanged.
Allow this PP interface to settle for s x 100 milliseconds
On wireless links, it is possible that the initial packets sent to the interface by the TCP layer may
be dropped by the network if they are sent too quickly after PPP negotiation has completed.
This setting defines the delay in notification sent to the TCP layer that PPP negotiation has
completed.
Enable “Always On” mode of this interface
If the Always on option is available on the interface, enabling this setting reveals the following
two radio buttons. When this functionality is enabled, the router will automatically try to
reconnect after about 10 seconds if the link becomes disconnected. This parameter should be
enabled when using AODI or W-WAN.
On
Default action, the interface will always try and raise this PPP link.
On and return to service immediately
These two radio buttons enable the Always on functionality and additionally the facility to
return to the in-service state after a disconnect event.
Put this interface “Out of Service” when an always-on connection attempt fails
Normally, always-on interfaces will not go out of service unless they have connected at least
once. When enabled, this setting causes the router to put the interface out of service even if the
first connection attempt fails.
