SNMP Management Mode
An SNMP managed network consists of two main types of component: agents and a manager. 
An agent is a management software module that resides in a managed device (the NWA). An agent 
translates the local management information from the managed device into a form compatible with 
SNMP. The manager is the console through which network administrators perform network 
management functions. It executes applications that control and monitor managed devices. 
SNMP allows a manager and agents to communicate for the purpose of accessing information such 
as packets received, node port status, etc.
Remote Management Limitations
Remote management over LAN or WLAN will not work when:
• You have disabled that service in one of the remote management screens.
• The IP address in the Secured Client IP field does not match the client IP address. If it does not 
match, the NWA will disconnect the session immediately.
• You may only have one remote management session running at one time. The NWA 
automatically disconnects a remote management session of lower priority when another remote 
management session of higher priority starts. The priorities for the different types of remote 
management sessions are as follows:
1
Telnet
2
HTTP
System Timeout
There is a default system management idle timeout of five minutes (three hundred seconds). The 
NWA automatically logs you out if the management session remains idle for longer than this
