17.3SNMP Agent

The SNMP agent (snmpd) listens to SNMP v1 queries (gets/sets) by default, evokes the corresponding MIB Module to process the request, and sends the SNMP response with return data to the SNMP/MIB manager. The agent can also be configured to respond to v3 queries. The SNMP agent in the CMM is implemented to support SNMP-get, SNMP-get-next, and SNMP-set for MIB- II and the CMM MIB objects.

All SNMP “set” queries are logged in the command log file.

Note: Changing IP addresses when using SNMP v3 will require a restart of the snmpd process. This is due to SNMP v3 using the IP address to generate the encryption keys. To restart the snmpd process follow steps 2 through 4 in Section 17.3.2.

17.3.1Configuring the SNMP Agent Port

The SNMP agent is set up to use port 161 by default. The port can be configured to use a different port number by adding the following line to the snmpd.conf file:

agentaddress port_number

17.3.2Configuring the Agent to Respond to SNMP v3 Requests

The agent can also be configured to respond to SNMP v3 queries, in which case it checks the security, decodes the request, then evokes the corresponding MIB Module to process the request, and sends the SNMP response with return data to the SNMP/MIB manager. SNMP v3 adds support for strong authentication and private communication.

To change the SNMP agent to respond to SNMP v3 queries:

1. Copy /etc/snmpdv3.conf to /etc/snmpd.conf by issuing the command:

cp /etc/snmpdv3.conf /etc/snmpd.conf

2. Find the process ID of the snmpd process by issuing the command:

ps -ax
