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
ZyXEL Device). 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.
The managed devices contain object variables/managed objects that define each
piece of information to be collected about a device. Examples of variables include
such as number of packets received, node port status etc. A Management
Information Base (MIB) is a collection of managed objects. SNMP allows a
manager and agents to communicate for the purpose of accessing these objects.

LABEL DESCRIPTION
Server Port The SNMP agent listens on port 161 by default. If you change the SNMP
server port to a different number on the ZyXEL Device, for example
8161, then you must notify people who need to access the ZyXEL Device
SNMP agent to use the same port.
Server Access Select the interface(s) through which a computer may access the ZyXEL
Device using this service.
Secured Client
IP Address A secured client is a “trusted” computer that is allowed to access the
SNMP agent on the ZyXEL Device.
Select All to allow any computer to access the SNMP agent.
Choose Selected to just allow the computer with the IP address that you
specify to access the SNMP agent.
