rtpMIB 1.3.6.1.2.1.87
The managed objects of RTP systems. The MIB is structured around three types of information. 1. General information about RTP sessions such as the session address. 2. Information about RTP streams being sent to an RTP session by a particular sender. 3. Information about RTP streams received on an RTP session by a particular receiver from a particular sender. There are two types of RTP Systems, RTP hosts and RTP monitors. As described below, certain objects are unique to a particular type of RTP System. An RTP host may also function as an RTP monitor. Refer to RFC 1889, 'RTP: A Transport Protocol for Real-Time Applications,' section 3.0, for definitions.

OBJECT IDENTIFIER    

rtpSessionNewIndex 1.3.6.1.2.1.87.1.1
This object is used to assign values to rtpSessionIndex as described in 'Textual Conventions for SMIv2'. For an RTP system that supports the creation of rows, the network manager would read the object, and then write the value back in the Set that creates a new instance of rtpSessionEntry. If the Set fails with the code 'inconsistentValue,' then the process must be repeated; If the Set succeeds, then the object is incremented, and the new instance is created according to the manager's directions. However, if the RTP agent is not acting as a monitor, only the RTP agent may create conceptual rows in the RTP session table.

rtpSessionInverseTable 1.3.6.1.2.1.87.1.2
Maps rtpSessionDomain, rtpSessionRemAddr, and rtpSessionLocAddr TAddress pairs to one or more rtpSessionIndex values, each describing a row in the rtpSessionTable. This makes it possible to retrieve the row(s) in the rtpSessionTable corresponding to a given session without having to walk the entire (potentially large) table.
Status: current Access: not-accessible

  SEQUENCE OF  
    RtpSessionInverseEntry

rtpSessionInverseEntry 1.3.6.1.2.1.87.1.2.1
Each entry corresponds to exactly one entry in the rtpSessionTable - the entry containing the tuple, rtpSessionDomain, rtpSessionRemAddr, rtpSessionLocAddr and rtpSessionIndex.
Status: current Access: not-accessible
OBJECT-TYPE    
  RtpSessionInverseEntry  

rtpSessionInverseStartTime 1.3.6.1.2.1.87.1.2.1.1
The value of SysUpTime at the time that this row was created.

  TimeStamp  

rtpSessionTable 1.3.6.1.2.1.87.1.3
There's one entry in rtpSessionTable for each RTP session on which packets are being sent, received, and/or monitored.
Status: current Access: not-accessible
OBJECT-TYPE    
  SEQUENCE OF  
    RtpSessionEntry

rtpSessionEntry 1.3.6.1.2.1.87.1.3.1
Data in rtpSessionTable uniquely identify an RTP session. A host RTP agent MUST create a read-only row for each session to which packets are being sent or received. Rows MUST be created by the RTP Agent at the start of a session when one or more senders or receivers are observed. Rows created by an RTP agent MUST be deleted when the session is over and there are no rtpRcvrEntry and no rtpSenderEntry for this session. An RTP session SHOULD be monitored to create management information on all RTP streams being sent or received when the rtpSessionMonitor has the TruthValue of 'true(1)'. An RTP monitor SHOULD permit row creation with the side effect of causing the RTP System to join the multicast session for the purposes of gathering management information (additional conceptual rows are created in the rtpRcvrTable and rtpSenderTable). Thus, rtpSessionTable rows SHOULD be created for RTP session monitoring purposes. Rows created by a management application SHOULD be deleted via SNMP operations by management applications. Rows created by management operations are deleted by management operations by setting rtpSessionRowStatus to 'destroy(6)'.
Status: current Access: not-accessible
OBJECT-TYPE    
  RtpSessionEntry  

rtpSessionIndex 1.3.6.1.2.1.87.1.3.1.1
The index of the conceptual row which is for SNMP purposes only and has no relation to any protocol value. There is no requirement that these rows are created or maintained sequentially.
Status: current Access: not-accessible
OBJECT-TYPE    
  Integer32 1..2147483647  

rtpSessionDomain 1.3.6.1.2.1.87.1.3.1.2
The transport-layer protocol used for sending or receiving the stream of RTP data packets on this session. Cannot be changed if rtpSessionRowStatus is 'active'.

OBJECT-TYPE    
  TDomain  

rtpSessionRemAddr 1.3.6.1.2.1.87.1.3.1.3
The address to which RTP packets are sent by the RTP system. In an IP multicast RTP session, this is the single address used by all senders and receivers of RTP session data. In a unicast RTP session this is the unicast address of the remote RTP system. 'The destination address pair may be common for all participants, as in the case of IP multicast, or may be different for each, as in the case of individual unicast network address pairs.' See RFC 1889, 'RTP: A Transport Protocol for Real-Time Applications,' sec. 3. The transport service is identified by rtpSessionDomain. For snmpUDPDomain, this is an IP address and even-numbered UDP Port with the RTCP being sent on the next higher odd-numbered port, see RFC 1889, sec. 5.
Status: current Access: read-create
OBJECT-TYPE    
  TAddress  

rtpSessionLocAddr 1.3.6.1.2.1.87.1.3.1.4
The local address used by the RTP system. In an IP multicast RTP session, rtpSessionRemAddr will be the same IP multicast address as rtpSessionLocAddr. In a unicast RTP session, rtpSessionRemAddr and rtpSessionLocAddr will have different unicast addresses. See RFC 1889, 'RTP: A Transport Protocol for Real-Time Applications,' sec. 3. The transport service is identified by rtpSessionDomain. For snmpUDPDomain, this is an IP address and even-numbered UDP Port with the RTCP being sent on the next higher odd-numbered port, see RFC 1889, sec. 5.
Status: current Access: read-only
OBJECT-TYPE    
  TAddress  

rtpSessionIfIndex 1.3.6.1.2.1.87.1.3.1.5
The ifIndex value is set to the corresponding value from IF-MIB (See RFC 2233, 'The Interfaces Group MIB using SMIv2'). This is the interface that the RTP stream is being sent to or received from, or in the case of an RTP Monitor the interface that RTCP packets will be received on. Cannot be changed if rtpSessionRowStatus is 'active'.
Status: current Access: read-create
OBJECT-TYPE    
  InterfaceIndex  

rtpSessionSenderJoins 1.3.6.1.2.1.87.1.3.1.6
The number of senders that have been observed to have joined the session since this conceptual row was created (rtpSessionStartTime). A sender 'joins' an RTP session by sending to it. Senders that leave and then re-join following an RTCP BYE (see RFC 1889, 'RTP: A Transport Protocol for Real-Time Applications,' sec. 6.6) or session timeout may be counted twice. Every time a new RTP sender is detected either using RTP or RTCP, this counter is incremented.

  Counter32  

rtpSessionReceiverJoins 1.3.6.1.2.1.87.1.3.1.7
The number of receivers that have been been observed to have joined this session since this conceptual row was created (rtpSessionStartTime). A receiver 'joins' an RTP session by sending RTCP Receiver Reports to the session. Receivers that leave and then re-join following an RTCP BYE (see RFC 1889, 'RTP: A Transport Protocol for Real-Time Applications,' sec. 6.6) or session timeout may be counted twice.

rtpSessionMonitor 1.3.6.1.2.1.87.1.3.1.10
Boolean, Set to 'true(1)' if remote senders or receivers in addition to the local RTP System are to be monitored using RTCP. RTP Monitors MUST initialize to 'true(1)' and RTP Hosts SHOULD initialize this 'false(2)'. Note that because 'host monitor' systems are receiving RTCP from their remote participants they MUST set this value to 'true(1)'.
Status: current Access: read-only
OBJECT-TYPE    
  TruthValue  

rtpSessionRowStatus 1.3.6.1.2.1.87.1.3.1.11
Value of 'active' when RTP or RTCP messages are being sent or received by an RTP System. A newly-created conceptual row must have the all read-create objects initialized before becoming 'active'. A conceptual row that is in the 'notReady' or 'notInService' state MAY be removed after 5 minutes.

  RowStatus  

rtpSenderInverseTable 1.3.6.1.2.1.87.1.4

This table allows management applications to find entries sorted by rtpSenderAddr rather than sorted by rtpSessionIndex. Given the rtpSessionDomain and rtpSenderAddr, a set of rtpSessionIndex and rtpSenderSSRC values can be returned from a tree walk. When rtpSessionIndex is specified in the SNMP Get-Next operations, one or more rtpSenderSSRC values may be returned.
