No PING response request interval (s):
If this parameter is set to a non-zero value the unit will use this value as the interval to ping at
when more than one ping request sent out the PPP interface is outstanding. This should be set
to a shorter interval than the PING request interval so that the unit may more quickly react to
a bro ken PPP link.
PING response timeout (s):
If this parameter is set to a non-zero value the unit will wait for the interval specified for a
response from a PING request before applying the No PING response request interval. If this
parameter is set to 0 (default), the time specified in the in PING Request interval is allowed
before applying the No PING response request interval.
New connections to resume with previous PING interval: If this parameter is set to “Yes”, the
unit will set the PING Request interval to the interval in use when the PPP last disconnected.
Only send PINGs when interface is in service:
If this parameter is set to “ON”, ICMP echo requests will only be sent from this interface when
it is in service. The default setting is “OFF”, ICMP echo requests are sent when the interface is
in service and out of service.
PING size (octets):
The parameter specifies the PING size when using interface autoping feature. The size indicates
how large the ICMP packet should be excluding the size of the IP header.
PING IP address:
This parameter specifies the IP address or host name to which ICMP echo requests will be sent
if the PING request interval is greater than 0.
Ping IP address #2:
This allows for more reliable problem detection before fail over occurs. If an IP address or host
name is entered and the Ping IP switchover count has a value greater than 0, when a ping failure
is detected on the primary IP address the 2nd IP address is checked. This is to ensure that if the
main IP address becomes unavailable for any reason and stops responding to ICMP requests, the
router will check another IP address before starting fail over procedures.
PING IP switchover count:
When set to more than 0, indicates the number pings that need to fail before the 2nd IP
address is checked.
No PING response reset delay (s):
This parameter is primarily used where IP traffic is being carried over a GPRS network and
the PPP instance has been configured for Always on mode. It specifies an amount of time after
which if no response has been received to the auto-pings, the unit will terminate the PPP con-
nection in an attempt to re-establish communications (because Always on mode has been
selected the unit will automatically attempt to re-establish a PPP connection that has been ter-
minated).
Use ETH0 for PING source IP:
Setting this parameter to “Yes” causes the unit to use the IP address of ETH0 (instead of the
cur rent IP address of the PPP interface), as the source address for the auto PING packets.
Reset Ping interval after traffic:
When enabled, the time configured in the PING request interval (s): parameter will be reset if
IP data is sent across the PPP link.
Settling time (*100ms):
On wireless links it is possible that initial packets sent to the PPP interface by TCP may be
dropped by the network if they are sent too quickly after PPP negotiation has been completed.
This parameter may be used to delay the notification to TCP that PPP has connected.
