The LEDI NETWORK TOP provides a SNMP v1 interface for fine monitoring and diagnos-
tics. The SNMP protocol allows the supervision of a device through the network. Two kind
of information are available through a SNMP interface:
►
A set of variables that can be read. These variables are stored together in a databa-
se (MIB) organized in a hierarchical way. The variables are set by the NTP software
to reflect its internal states.
►
Some traps that can be generated by the NTP software to indicate important state
modification.
There is two important parts in the MIB:
►
A general-purpose branch named System. This branch is MIB II compatible.
►
A private branch that contains informations specific to the LEDI NETWORK TOP
product.

network-tOP\MIB:
