Chapter 6. SNMP Operation
49 Version 1.2 Apr 2006
Enterprise-specific MIB's are published and distributed by their creators, who are responsible
for their contents.
The MIB supported by the Fiber Multiplexer SNMP Agent follows RFC 1158 (MIB-II
standard).
6.5 SNMP Communities
To enable the delimitation of management domains, SNMP uses "communities". Each
community is identified by a name, which is an alphanumeric string of up to 255 characters defined
by the user. Any SNMP entity (this term includes both managed nodes and management stations) is
assigned by its user a community name. In parallel, the user defines for each SNMP entity a list of
the communities which are authorized to communicate with it, and the access rights associated with
each community (this is the SNMP community name table of the entity).
In general, SNMP agents support two types of access rights:
Read-only the SNMP agent accepts and processes only SNMP getRequest
and getNextRequest commands from management stations
which have a read-only community name.
Read-write the SNMP agent accepts and processes all the SNMP
commands received from a management station with a read-write
community name. SNMP agents are usually configured to send traps to
management stations having read-write communities.
6.6 Configuring the SNMP Agent
The agent for the Fiber Multiplexer resides in the SNMP option card installed in the Fiber
Multiplexer. Configuration of the agent is accomplished via the RS-232 Control Port of the Fiber
Multiplexer. From the Define System Parameter menu select "9", SNMP Agent.
