Appendix C SNMP Management Installation and Operation Manual

C-4 SNMP Environment IPmux-8/16 Ver. 6.00

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.

Authentication

In accordance with SNMP protocol, the SNMP community of the originating entity

is sent in each message.

When an SNMP message is received by the addressed entity, it first checks the

originator's community. Messages with community names not included in the

SNMP community names table of the recipient are discarded. SNMP agents of

managed entities usually report this event by means of an authentication failure

trap.

The SNMP agents of managed entities evaluate messages originated by

communities appearing in the agent's SNMP community names table in

accordance with the access rights, as previously explained. Thus, a setRequest for

a MIB object with read-write access rights will nevertheless be rejected if it comes

from a management station whose community has read-only rights with respect to

that particular agent.

Network Management Stations

The IPmux-8/16 SNMP agent stores the IP address of the Network Management

Station (NMS) that is intended to manage it.
