ROHC-MIB Table View

This table lists and describes all ROHC channels
per interface.

rohcChannelEntry row .1.3.6.1.2.1.112.1.1.1.1

An entry describing a particular script. Every script that
is stored in non-volatile memory is required to appear in

this script table.

rohcChannelStatus Status of the channel.	Enumeration Enumerated Values: 1 enabled 2 disabled	.1.3.6.1.2.1.112.1.1.1.1.6

This table lists properties of running instances
of robust header compressors and decompressors
at IP interfaces.  It is indexed by interface number,
the type of instance (compressor or decompressor),
and the ID of the channel used by the instance as
ROHC channel.
          
Note that the rohcChannelID uniquely identifies an
instance.  The ifIndex and rohcInstanceType are part
of the index, because it simplifies accessing instances
per interface and for addressing either compressors or
decompressors only.

rohcInstanceEntry row .1.3.6.1.2.1.112.1.1.2.1

An entry describing a particular instance
of a robust header compressor or decompressor.
