Attribute
Meaning
NAT Enable/Disable
This parameter enables or disables the Network Address Translation (NAT)
feature for the SM. NAT isolates devices connected to the Ethernet or wired
side of a SM from being seen directly from the wireless side of the SM. With
NAT enabled, the SM has an IP address for transport traffic separate from its
address for management, terminates transport traffic, and allows you to
assign a range of IP addresses to devices that are connected to the Ethernet
or wired side of the SM.
When NAT is enabled, VLANs are not supported on the wired side of that
SM. You can enable NAT in SMs within a sector where VLAN is enabled in
the AP/BHM, but this may constrain network design.
IP Address
This field displays the IP address for the SM. DHCP Server
will not
automatically assign this address when NAT is disabled.
Subnet Mask
This field displays the subnet mask for the SM. DHCP Server
will not
automatically assign this address when NAT is disabled.
Gateway IP Address
This field displays the gateway IP address for the SM. DHCP Server
will not
automatically assign this address when NAT is disabled.
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 120 minutes. This action makes additional
resources available for greater traffic than the default value accommodates.
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.
Translation Table Size Total number of minutes that have elapsed since the last packet transfer
between the connected device and the SM/BHS.
