| rohcChannelID |
.1.3.6.1.2.1.112.1.1.1.1.2 |
|
The locally arbitrary, but unique identifier associated
with this channel. The value is REQUIRED to be unique
per ROHC MIB implementation independent of the associated
interface.
The value is REQUIRED to remain constant at least from one
re-initialization of the entity's network management system
to the next re-initialization. It is RECOMMENDED that the
value persist across such re-initializations.
|
| rohcChannelType |
.1.3.6.1.2.1.112.1.1.1.1.3 |
|
Type of usage of the channel. A channel might be currently
not in use for ROHC or feedback, it might be in use as
a ROHC channel carrying packets and optional piggy-backed
feedback, or it might be used as a dedicated feedback
channel exclusively carrying feedback.
|
| rohcChannelFeedbackFor |
.1.3.6.1.2.1.112.1.1.1.1.4 |
|
The index of another channel of this interface for which
the channel serves as feedback channel.
If no feedback information is transferred on this channel,
then the value of this ID is 0. If the channel type is set
to notInUse(1), then the value of this object must be 0.
If the channel type is rohc(2) and the value of this object
is a valid channel ID, then feedback information is
piggy-backed on the ROHC channel. If the channel type is
dedicatedFeedback(3), then feedback is transferred on this
channel and the value of this object MUST be different from
0 and MUST identify an existing ROHC channel.

to initialize rohcContexStorageTime object when a new
context is created.
Changing the value of an rohcInstanceContextStorageTime
instance does not affect any entry of the rohcContextTable

|
| rohcContextCIDState |
.1.3.6.1.2.1.112.1.2.1.3 |
|
State of the CID. When a CID is assigned to a context,
its state changes from `unused' to `active'. The active
context may stop operation due to some explicit
signalling or after observing no packet for some specified
time. In the first case then the CID state changes to
`terminated', in the latter case it changes to `expired'.
If the CID is re-used again for another context, the
state changes back to `active'.
|
| rohcContextProfile |
.1.3.6.1.2.1.112.1.2.1.4 |
|
Identifier of the profile for this context.
The profile is identified by its index in the
rohcProfileTable for this instance. There MUST exist a
corresponding entry in the rohcProfileTable using the
value of rohcContextProfile as second part of the index
(and using the same rohcChannelID as first part of the
index).

|
This object indicates whether reverse decompression, for
example as described in RFC 3095, Section 6.1, is used
on this channel or not, and if used, to what extent.
Its value is only valid for decompressor contexts, i.e.,
if rohcInstanceType has the value decompressor(2). For
compressor contexts where rohcInstanceType has the value
compressor(1), the value of this object is irrelevant
and MUST be set to zero (0).
The value of the reverse decompression depth indicates
the maximum number of packets that are buffered, and thus
possibly be reverse decompressed by the decompressor.
A zero (0) value means that reverse decompression is not
used.
|
| rohcContextStorageTime |
.1.3.6.1.2.1.112.1.2.1.6 |
|
The value of this object specifies how long this row
can exist in the rohcContextTable after the
rohcContextCIDState switched to expired(3) or
terminated(4). This object returns the remaining time
that the row may exist before it is aged out. The object
is initialized with the value of the associated
rohcContextStorageTime object. After expiration or
termination of the context, the value of this object ticks
backwards. The entry in the rohcContextTable is destroyed
when the value reaches 0.
The value of this object may be set in order to increase or
reduce the remaining time that the row may exist. Setting
the value to 0 will destroy this entry as soon as the
rochContextCIDState has the value expired(3) or
terminated(4).
Note that there is no guarantee that the row is stored as
long as this object indicates. In case of limited CID
space, the instance may re-use a CID before the storage
time of the corresponding row in rohcContextTable reaches
the value of 0. In this case the information stored in this
row is not anymore available.

| rohcContextDeactivationTime |
.1.3.6.1.2.1.112.1.2.1.8 |
|
The date and time when the context stopped being able to
compress packets or decompress packets, respectively,

The value '0000000000000000'H is returned if the context
has not been deactivated yet.
