Operational Status Queries MN/22156, rev 12
F-4 VMS User Guide
Operational Status Queries
The VMS exposes certain operational status via SNMP to external agents. The
status is exposed as a set of virtual SNMP entities identified via a unique
community string. Branches of the defined MIBs are only valid on certain enti-
ties.
The following table describes the exposed entities, and what branch of the MIB
they support.
Entity Identifiers
The unique identifier for the system entity is the community string “server”. The
other identifiers are for the purpose of the SNMP agent, without format, and can
only be obtained via queries to other entities. The exception is the unit which
can also be referenced via the same community string used to perform a proxied
request to the associated physical hardware.
As an example, the modulator identifier for the first modulator subcomponent of
a modem with the IP address 172.18.100.1 can be obtained by querying the
VMS for the “modulatorId” variable of the switching MIB, with an instance of 1
and a community string of “[email protected]”. The resulting octet string
will be the entity identifier “moniker” to be used as the community when query-
ing related MIB variables.
