VOP1224-61 User’s Guide

SNMP itself is a simple request/response protocol based on the manager/agent

model. The manager issues a request and the agent returns responses using the

following protocol operations:

14.3.1 Supported MIBs

MIBs let administrators collect statistics and monitor status and performance. The

VOP supports the following MIBs:

• MIB II IF MIB and ADSL line MIB (RFC-2662)

• SNMP MIB II (RFC-1215)

• BRIDGE MIB: FDB status

The VOP can also respond with specific data from the DSLAM private MIBs:

•zyxel.mib

• zyxel-iesCommon.mib

• zyxel-vop1224-61.mib

14.3.2 SNMP Traps

The VOP can send the following SNMP traps to an SNMP manager when an event

occurs. ATUC refers to the downstream channel (for traffic going from the VOP to

the subscriber). ATUR refers to the upstream channel (for traffic coming from the

subscriber to the VOP).

Table 21 SNMP Commands

COMMAND DESCRIPTION

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.
