Nortel Business Secure Router 252 Configuration — Basics
• Get-Allows the manager to retrieve an object variable from the agent.
• 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.
Supported MIBs
The Business Secure Router supports MIB II, which is defined in RFC 1213 and
RFC 1215. The focus of the MIBs is to let administrators collect statistical data
and monitor status and performance.
SNMP Traps
The Business Secure Router sends traps to the SNMP manager when any one of
the following events occurs:
