vismRtcpRepInterval
Module: CISCO-VISM-MODULE-MIB
OID (symbolic): CISCO-VISM-MODULE-MIB::vismRtcpRepInterval
OID (numeric): 1.3.6.1.4.1.351.110.3.17.2.2
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: This attribute defines the RTCP(Real-time Transport Control Protocol) report interval (defined in RFC 1889). This indicates the interval at which the RTCP reports should be sent to the participating members. The RTCP reports are not sent at a fixed rate at this interval. Rather, this value is used as a base value to arrive at a random number between 0.5 and 1.5 times this value.
This interval timer also serves the purpose of RTP packets receive timer. At every vismRtcpRecvMultiplier times this interval, where vismRtcpRecvMultiplier is specified in the MIB object below, a check is made on a VoIP connection (which is in SENDRECV or RECVONLY xGCP modes) to see if any RTP packets have been received. If not, gateway-initiated DLCX should be sent to the Call Agent.
Currently, this interval timer is a card-specific value, which means the value is configurable on a per card basis and not on a per call basis.
This value is applicable for VoIP adaptation only.
What is vismRtcpRepInterval?
This Integer32 (500..15000), in milliseconds, defines the base RTCP report interval per RFC 1889, with actual reports sent at a randomized time between 0.5 and 1.5 times this base value rather than at a fixed rate. This governs how often the card exchanges RTCP quality-monitoring reports with call participants, which an admin can tune to balance monitoring granularity against control-plane bandwidth usage. For example, an admin wanting finer-grained real-time quality feedback for VoIP calls might lower vismRtcpRepInterval, accepting the tradeoff of more frequent RTCP traffic.
