ConfigServer IP Port
: This field requires information only when the router is operating in
Normal mode (See “MODE” above). This is the IP unicast port of the configuration server for
this channel. To change the port, type in the new port number (0-65535), and click the
Submit
Changes
button. The default designated port for 852 servers is 1629.
Serial Transaction Mode
: These radio buttons allow the user to enable or disable Serial
Transaction Mode. When enabled the Router will send out 852 configuration updates serially in
a round robin fashion to the other 852 devices on the channel instead of in parallel. This means
that an update transaction has to complete or time-out with one device before a new
transaction is started with the next device. This mode significantly reduces bursts of traffic
when devices are added to a channel or their routing data is changed. This may be helpful for
low bandwidth 852 channels. Select the new value and click the
Submit Changes
button.
Serial Transaction Interval
: This field sets the time interval between successive configuration
transactions when Serial Transaction Mode is enabled. The default is 1000 ms. This enables the
user throttle the rate at which configuration updates are sent out on the channel and thereby
manage traffic. This may be helpful for low bandwidth 852 channels. Enter the new value and
click the
Submit Changes
button.
Loop Detect Interval
: This value determines the number of milli-seconds between transmission
of a loop detection packet. A value of zero disables this feature. The default value is 5000 ms or
5 seconds. Setting this value to much below 1000 is not recommended. If the Loop Detection
finds a loop in the network routing, it will cause the eNodeIV to go un-configured to prevent
runaway traffic. A loop is detected if the router receives its own loop detection message on the
opposite side of the router. The router will continue to send loop detection messages and will
resume operation once the loop condition is removed. Click
Submit Changes
and the new value
is immediately in effect.
Loop Recover Retries
: This value determines the number of unsuccessful retires of the loop
detection message before a loop condition is considered to have been remedied. The default is
three. The minimum allowed value is two. Click
Submit Changes
and the new value is
immediately in effect.
Redundant Router Detect
: These radio buttons allow the user to enable or disable the
detection of redundant 852 routers on the 852 channel. When enabled, no CN data packets are
forwarded to any redundant routers. This prevents loops due to redundant routers from
occurring. Click
Submit Changes
and the new value is immediately in effect.
Loop Check on Boot
: These radio buttons allow the user to change the boot up mode of the
router with respect to loop detection. When enabled, the router will not forward CN data
packets until after a loop check has completed and no loops were detected. This adds an
additional delay at boot-up before the router will begin forwarding packets. The length of the
delay is equal to the
Loop Detect Interval
times the number of
Loop Recover Retries
. When
disabled, the router will immediately begin forwarding packets on boot-up. Click
Submit
Changes
and the new value is immediately in effect.
