802.3 Link Enable/Disable
Specify whether to enable or disable Ethernet/802.3 connectivity on the wired port of
the SM. This parameter has no effect on the wireless link. When you select Enable, this
feature allows traffic on the Ethernet/802.3 port. This is the factory default state of the
port. When you select Disable, this feature prevents traffic on the port. Typical cases
of when you may want to select Disable include:
◦ The subscriber is delinquent with payment(s).
◦ You suspect that the subscriber is sending or flooding undesired broadcast
packets into the network, such as when
• a virus is present in the subscriber's computing device.
• the subscriber's home router is improperly configured.
Webpage Auto Update
Enter the frequency (in seconds) for the web browser to automatically refresh the web-
based interface. The default setting is 0. The 0 setting causes the web-based interface to
never be automatically refreshed.
Bridge Entry Timeout
Specify the appropriate bridge timeout for correct network operation with the existing
network infrastructure. Timeout occurs when the AP encounters no activity with the SM
(whose MAC address is the bridge entry) within the interval that this parameter specifies.
The Bridge Entry Timeout should be a longer period than the ARP (Address Resolution
Protocol) cache timeout of the router that feeds the network.
This parameter governs the timeout interval, even if a router in the system has a longer
timeout interval. The default value of this field is 25 minutes.
CAUTION!
An inappropriately low Bridge Entry Timeout setting may lead to temporary
loss of communication with some end users.
SM Power Up Mode With No 802.3 Link
Specify the default mode in which this SM will power up when the SM senses no Ethernet
link. Select either
• Power Up in Aim Mode—the SM boots in an aiming mode. When the SM
senses an Ethernet link, this parameter is automatically reset to Power Up in
Operational Mode. When the module senses no Ethernet link within 15 minutes
after power up, the SM carrier shuts off.
• Power Up in Operational Mode—the SM boots in Operational mode. The
module attempts registration. Unlike in previous releases, this is the default
selection in Release 8.
2X Rate
Disable this parameter to facilitate initial aiming from the destination. Then see 2X
Operation on Page 90.
