snmpmibd Daemon

Purpose

Starts the snmpmibd dpi2 sub-agent daemon as a background process.

Syntax

snmpmibd [ -f File ] [ -d [Level] ] [ -h HostName ] [ -c Community ]

Description

The snmpmibd command starts the snmpmibd dpi2 sub-agent. This command may only be issued by a user with root privileges or by a member of the system group.

The snmpmibd daemon complies with the standard Simple Network Management Protocol Distributed Protocl Interface Version 2.0 defined by RFC 1592. It acts as a dpi2 sub-agent to communicate with the dpi2 agent through dpiPortForTCP.0 (1.3.6.1.4.1.2.2.1.1.1.0) which is defined in RFC1592 section 3.1.

The Management Information Base(MIB) is defined by RFC 1155. The specific MIB variables snmpmibd is managing are defined by the following RFCs:

RFC 1213: MIB-II
RFC 1229: Extension to the Generic-Interface MIB
RFC 1231: IEEE 802.5 Token Ring MIB
RFC 1398: Ethernet-like Interface Types MIB
RFC 1512: FDDI MIB

Note

The "system" and "snmp" groups defined in RFC1213 are not implemented by snmpdmibd daemon. Instead they are implemented by snmpdv3 agent.

The snmpmibd daemon is normally executed during system startup when /etc/rc.tcpip shell script is called.

The snmpmibd daemon should be controlled using the System Resource Controller(SRC). Entering snmpmibd at the command line is not recommended.

Use the following SRC commands to manipulate the snmpmibd daemon:

startsrc: Starts a subsystem, group of subsystems, or a subserver.
stopsrc: Stops a subsystem, group of subsystems, or a subserver.
refresh: Causes a subsystem or group of subsystems to reread the appropriate configuration file.
lssrc: Gets the status of a subsystem, group of subsystems, or a subserver. If the user issuing the long status form of the lssrc command is not the root user, no community name information is displayed.

Flags

-c Community	Use specified community name. If -c flag is not specified, the default community name is public.
-d [Level]	Specifies tracing/debug level. The levels are: 8 DPI level 1 16 DPI level 2 32 Internal level 1 64 Internal level 2 128 Internal level 3 Add the numbers for multiple trace levels. If -d flag is specified and the Level is not specified, the default level is 56. If -d flag is not specified, the default level is 0.
-f File	A non-default configuration file. If the -f flag is not specified, the default configuration file is /etc/snmpmibd.conf. See /etc/snmpmibd.conf file for information on this file format.
-h HostName	Send request to specified host. If -h flag is not specified, the default destination host is loopback (127.0.0.1).

Examples

To start the snmpmibd daemon, enter a command similar to the following:
```
startsrc -s snmpmibd -a "-f /tmp/snmpmibd.conf"
```
This command starts the snmpmibd daemon and reads the configuration file from /tmp/snmpmibd.conf.
To stop the snmpmibd daemon normally, enter:
```
lssrc -s hostmbid
```
This command returns the name of the daemon, the process ID of the daemon, and the state of the daemon (active or inactive).
To get long status from the snmpmibd daemon, enter:
```
lssrc -ls snmpmibd
```
If you are the root user, this long form of the status report lists the configuration parameters in /etc/snmpmibd.conf.

Files

/etc/snmpmibd.conf	Defines the configuration parameters for snmpmibd command.
/etc/mib.defs	Defines the Management Information Base (MIB) variables the SNMP agent and manager should recognize and handle.
