Chapter 43 System
• GetNext - Allows the manager to retrieve the next object variable from a table
or list within an agent. In SNMPv1, when a manager wants to retrieve all
elements of a table from an agent, it initiates a Get operation, followed by a
series of GetNext operations.
• Set - Allows the manager to set values for object variables within an agent.
• Trap - Used by the agent to inform the manager of some events.

43.11.1 Supported MIBs

The ZyWALL supports MIB II that is defined in RFC-1213 and RFC-1215. The
ZyWALL 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 ZyWALL's MIBs from
www.zyxel.com.
