"This MIB module defines a set of objects for monitoring

The objects are specific to ROHC RTP (profile 0x0001),
ROHC UDP (profile 0x0002), and ROHC ESP (profile 0x0003)
defined in RFC 3095 and for the ROHC LLA profile (profile
0x0005) defined in RFC 3242.

"Boolean, only applicable to compressor contexts using the

pad every RHP packet with a minimum of one octet ROHC
padding.
The value of this object is only valid for LLA profiles,

DESCRIPTION
"Boolean, only applicable to compressor contexts using the
LLA profile. It specifies how to handle packets that do
not fit any of the preferred packet sizes specified. If
its value is true, the compressor must deliver the larger
packet as-is and must not use segmentation. If it is set
to false, the ROHC segmentation scheme must be used to
split the packet into two or more segments, and each
segment must further be padded to fit one of the preferred
packet sizes.
The value of this object is only valid for LLA profiles,
i.e., if the corresponding rohcProfile has a value of
0x0005. If the corresponding rohcProfile has a value
other than 0x0005, then this object MUST NOT be

"This object is only applicable to compressor contexts

with which a packet validating the context must be sent.
This tells the compressor that a packet containing a CRC
field must be sent at least once every N packets, where N
is the value of the object. A value of 0 indicates that
periodical verifications are disabled.
The value of this object is only valid for LLA profiles,
i.e., if the corresponding rohcProfile has a value of
0x0005. If the corresponding rohcProfile has a value
other than 0x0005, then this object MUST NOT be
