Chapter 16 Remote Management
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.
16.5.1 Configuring SNMP
To change your ZyXEL Device’s SNMP settings, click Advanced > Remote MGMT > SNMP tab. The screen appears as shown.
Figure 92 Advanced > Remote MGMT > SNMP
The following table describes the labels in this screen.
Table 66 Advanced > Remote MGMT > SNMP
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 | A secured client is a “trusted” computer that is allowed to access the |
IP Address | 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. |
