Radio Public Network Interface Configuration, IP Address
If DHCP Client is enabled, then the DHCP server automatically assigns this address.
Otherwise, assign the IP address for over-the-air management of the SM when the radio
public interface is enabled in the next parameter.
Radio Public Network Interface Configuration, Interface Enable/Disable
If you want over-the-air management capability for the SM, select Enabled. If you want to
limit management of the SM to its Ethernet interface, select Disabled.
Radio Public Network Interface Configuration, Subnet Mask
If DHCP Client is enabled, then the DHCP server automatically assigns this subnet mask.
Otherwise, assign the subnet mask for over-the-air management of the SM when the
radio public interface is enabled.
Radio Public Network Interface Configuration, Gateway IP Address
If DHCP Client is enabled, then the DHCP server automatically assigns this gateway IP
address. Otherwise, assign the gateway IP address for over-the-air management of the
SM when the radio public network interface is enabled.
RECOMMENDATION:
Note or print the IP settings from this page. Ensure that you can readily associate
these IP settings both with the module and with the other data that you store
about the module.
Radio Public Network Interface Configuration, DHCP State
If you select Enabled, the DHCP server automatically assigns the IP configuration
(IP address, subnet mask, and gateway IP address) and the values of those individual
parameters (above) are not used. The setting of this DHCP state parameter is also
viewable, but not settable, in the Network Interface tab of the Home page.
ARP Cache Timeout
If a router upstream has an ARP cache of longer duration (as some use 30 minutes),
enter a value of longer duration than the router ARP cache. The default value of this field
is 20 minutes.
TCP Session Garbage Timeout
Where a large network exists behind the SM, you can set this parameter to lower than
the default value of 1440 minutes (24 hours). This action makes additional resources
available for greater traffic than the default value accommodates. The default value of
this parameter is 120 minutes.
UDP Session Garbage Timeout
You may adjust this parameter in the range of 1 to 1440 minutes, based on network
performance. The default value of this parameter is 4 minutes.
