The Transmission Group
Based on the transmission media underlying each interface on a system, the
corresponding portion of the Transmission group is mandatory for that system.
When Internet-standard definitions for managing transmission media are defined,
the transmission group is used to provide a prefix for the names of those objects.
Typically, such definitions reside in the experimental portion of the MIB until they
are "proven", then as a part of the Internet standardization process, the definitions
are accordingly elevated and a new object identifier, under the transmission group
is defined. By convention, the name assigned is:
type OBJECT IDENTIFIER ::= { transmission number }.
Where "type" is the symbolic value used for the media in the ifType column of the
ifTable object, and "number" is the actual integer value corresponding to the
symbol.

The SNMP Group
Implementation of the SNMP group is mandatory for all systems which support an
SNMP protocol entity. Some of the objects defined below will be zero-valued in
those SNMP implementations that are optimized to support only those functions
specific to either a management agent or a management station. In particular, it
should be observed that the objects below refer to an SNMP entity, and there may
be several SNMP entities residing on a managed Node.
snmpInPkts (1.3.6.1.2.1.11.1)
