SNMP Agent Components
This section provides key information for system administrators responsible for setting up
SNMP-management on the Makito X.
snmpd
snmpd
is an SNMP agent that binds to a port and listens for requests from SNMP manage-
ment software. Upon receiving a request, it performs the requested operation, either
retrieving information or configuring the system. When finished processing the request, the
agent sends a response to the sender with the requested information or the status of the
configuration operation.
When you start an SNMP agent on a Makito X using the
service snmp start
command,
it loads the management database with the MIB files in the directory
/usr/share/snmp/mibs
and configures the agent with the files in
/usr/share/snmp
.
snmpd.conf
snmpd.conf
is the configuration file that defines how the SNMP agent works. You may
need to edit this file to specify the location of the Network Management System (NMS).
However, for most settings, it is preferable to use the
nmcfg
configuration script. On the
Makito X, the
snmpd.conf
file includes:
•
access control setup (i.e., community and user privileges),
•
system information setup (e.g., system location, services and contact),
snmpd.conf
is located in the directory
/usr/share/snmp
.
For a detailed description, see the
snmpd.conf
file.
snmpd.local.conf
snmpd.local.conf
is the configuration file that defines the VACM (View-based Access
Control Model) views modeling the privilege levels of the Makito X user groups: admins,
operators, and users. These groups can be used for v1/v2c communities and v3 USM users.
This file cannot be modified. Access groups are used in place of the traditional
ro
(read-
only) and
rw
(read-write) permissions when setting communities’ and users’ access with
the
nmcfg
configuration script.
