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" REVISION "200406030000Z" -- June 3, 2004 DESCRIPTION "Initial version, published as RFC 3816." ::= { mib-2 114 }---- The groups defined within this MIB module:--rohcRtpObjects OBJECT IDENTIFIER ::= { rohcRtpMIB 1 }rohcRtpConformance OBJECT IDENTIFIER ::= { rohcRtpMIB 2 }---- Context Table---- The rohcRtpContextTable lists all contexts per interface-- and instance.

States initAndRefresh(1), firstOrder(2), and secondOrder(3) are states of compressor contexts, states noContext(4), staticContext(5) and fullContext(6) are states of decompressor contexts."

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." REFERENCE "RFC 3242, Section 5.1.1" DEFVAL { false } ::= { rohcRtpContextEntry 5 }rohcRtpContextLargePktsAllowed OBJECT-TYPE SYNTAX TruthValue MAX-ACCESS read-only STATUS current 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 instantiated."

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."

For compressor contexts where rohcInstanceType has the value compressor(1), this object MUST NOT be instantiated. This object contains the number of different packet sizes that may be used in the context."

For compressor contexts where rohcInstanceType has the value compressor(1), this object MUST NOT be instantiated. This object contains the number of different packet sizes that are used in the context." REFERENCE "RFC 3095, Section 6.3.1" ::= { rohcRtpContextEntry 9 }rohcRtpContextACKs OBJECT-TYPE SYNTAX Counter32 MAX-ACCESS read-only STATUS current DESCRIPTION "The number of all positive feedbacks (ACK) sent or received in this context, respectively. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. For checking ifCounterDiscontinuityTime, the interface index is required. It can be determined by reading the rohcChannelTable of the ROHC-MIB." REFERENCE "RFC 3095, Section 5.2.1." ::= { rohcRtpContextEntry 10 }rohcRtpContextNACKs OBJECT-TYPE SYNTAX Counter32 MAX-ACCESS read-only STATUS current DESCRIPTION "The number of all dynamic negative feedbacks (ACK) sent or received in this context, respectively. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. For checking ifCounterDiscontinuityTime, the interface index is required. It can be determined by reading the rohcChannelTable of the ROHC-MIB." REFERENCE "RFC 3095, Section 5.2.1." ::= { rohcRtpContextEntry 11 }rohcRtpContextSNACKs OBJECT-TYPE SYNTAX Counter32 MAX-ACCESS read-only STATUS current DESCRIPTION "The number of all static negative feedbacks (ACK) sent or received in this context, respectively. Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime. For checking ifCounterDiscontinuityTime, the interface index is required. It can be determined by reading the rohcChannelTable of the ROHC-MIB."
