SNMP Agent
Simple Network Management Protocol (SNMP) is a standard
management protocol for multi-vendor IP networks. Each CoreBuilder
7000 family ATM switch has one SNMP agent that monitors objects on
the switch and may report data to one or more network management
systems.
Management
Information Base
(MIB)
Managed objects are accessed via a virtual information store, termed the
Management Information Base (MIB). Information defined in
industry-standard, de-facto standard, and enterprise-specific (proprietary)
MIBs supported by the CoreBuilder 7000 family ATM switch can be
accessed. These MIBs are collections of related managed objects, such as
error counters, ports, and network policies.
The CoreBuilder 7000 family ATM switch ATM switch supports the
following MIBs:
n
MIB II (RFC 1213)
n
AToM MIB (RFC 1695)
n
AToM 2 (circuit statistics)
n
ELAN MIB
n
LES MIB
n
LAN EMULATION BUS MIB
n
RMon 2 MIB (probe config)
n
Private chassis MIB
n
Private baseline MIB
Additional MIBs are supported by the CoreBuilder 7X00 interface cards
through the Single IP mode of the CoreBuilder 7000.
SNMP Traps An SNMP trap is an asynchronous report of a MIB event to the Network
Management Station; it is sent to the NMS address. Table 45 lists the
traps are currently supported by the CoreBuilder 7000 family ATM switch:
