Template:FAQ:Agent 37

Some operating systems will provide a mechanism for determining the speed and type of network interfaces, but many do not. In such cases, the agent attempts to guess the most appropriate values, usually based on the name of the interface.

The snmpd.conf directive 'interface' allows you to override these guessed values, and provide alternative values for the name, type and speed of a particular interface. This is particularly useful for fast-ethernet, or dial-up interfaces, where the speed cannot be guessed from the name.

See the snmpd.conf(5) man page for details.
