Maintenance
12.1  Overview
Use these screens to manage and maintain your WiMAX Device.
12.1.1  What You Need to Know
The following terms and concepts may help as you read through this chapter.
Remote Management Limitations
Remote management over LAN or WAN will not work when:
1
You have disabled that service in one of the remote management screens.
2
The IP address in the Secured Client IP field does not match the client IP address. If it does not 
match, the WiMAX Device will disconnect the session immediately.
3
There is already another remote management session with an equal or higher priority running. You 
may only have one remote management session running at one time.
Remote Management and NAT
When NAT is enabled:
• Use the WiMAX Device’s WAN IP address when configuring from the WAN. 
• Use  the  WiMAX  Device’s  LAN  IP  address when configuring from the LAN.
System Timeout
There is a default system management idle timeout of five minutes. The WiMAX Device 
automatically logs you out if the management session remains idle for longer than this timeout 
period. The management session does not time out when a statistics screen is polling.
SNMP
Simple Network Management Protocol (SNMP) is a protocol used for exchanging management 
information between network devices. SNMP is a member of the TCP/IP protocol suite. Your WiMAX 
Device supports SNMP agent functionality, which allows a manager station to manage and monitor 
the WiMAX Device through the network. The WiMAX Device supports SNMP version one (SNMPv1) 
and version two (SNMPv2). The next figure illustrates an SNMP management operation.
