rohcRtpMIB 1.3.6.1.2.1.114
This MIB module defines a set of objects for monitoring and configuring RObust Header Compression (ROHC). 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. Copyright (C) The Internet Society (2004). The initial version of this MIB module was published in RFC 3816. For full legal notices see the RFC itself or see: http://www.ietf.org/copyrights/ianamib.html

rohcRtpContextAlwaysPad 1.3.6.1.2.1.114.1.1.1.5
Boolean, only applicable to compressor contexts using the LLA profile. If its value is true, the compressor must pad every RHP packet with a minimum of one octet ROHC padding. 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 instantiated.

rohcRtpContextLargePktsAllowed 1.3.6.1.2.1.114.1.1.1.6
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 instantiated.

rohcRtpContextVerifyPeriod 1.3.6.1.2.1.114.1.1.1.7
This object is only applicable to compressor contexts using the LLA profile. It specifies the minimum frequency 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 instantiated.
