2.15.2.4. SNMP
Fig. 106. SNMP settings.
The IWE3200 can be managed by SNMP (Simple Network Management Protocol), and the SNMP
management functionality can be disabled. You can specify the name (used as a password) of the
read-only and read-write community. In addition, up to 5 SNMP trap targets can be set in the SNMP
Trap table.
To specify a trap target:
1. Type the IP address of the target host.
2. Type the Community for the host.
3. Select the corresponding check box next to the IP address text box.
2.15.3. LAN Device Management
Fig. 107. LAN device management settings.
LAN device management is for the IWE3200 to pass management requests from the Internet through
its built-in NAT server to devices on the private network. As a result, network devices (such as access
points) behind the NAT server can be managed from the Internet. In this way, the access Router acts
as a management proxy for the LAN devices. In addition, the IWE3200 can periodically check
whether the managed devices are working by PINGing them (Check devices if alive every n min-
utes). If it detects a device not working, it can send an SNMP trap (remote system logging) to a
back-end server to report such a situation (see Section 2.15.2.3 for more information). The LAN de-
vice management functionality is especially useful for a WISP to remotely manage deployed APs that
are usually invisible from the Internet due to the employment of NAT for IP address space conserva-
tion.
