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 Supported MIBs
The ZyXEL Device supports MIB II that is defined in RFC-1213 and RFC-1215. The
ZyXEL Device also supports private MIBs (zywall.mib and zyxel-zywall-ZLD-
Common.mib) to collect information about CPU and memory usage and VPN total
throughput. The focus of the MIBs is to let administrators collect statistical data
and monitor status and performance. You can download the ZyXEL Device’s MIBs
from www.zyxel.com.
16.5.2 SNMP Traps
The ZyXEL Device will send traps to the SNMP manager when any one of the
following events occurs.
Table 64 SNMP Traps
OBJECT LABEL OBJECT ID DESCRIPTION
Cold Start 1.3.6.1.6.3.1.1.5.1 This trap is sent when the ZyXEL Device is
turned on or an agent restarts.
linkDown 1.3.6.1.6.3.1.1.5.3 This trap is sent when the Ethernet link is
down.
linkUp 1.3.6.1.6.3.1.1.5.4 This trap is sent when the Ethernet link is
up.
