The date on which the trap was received

Oct 20

2

The time at which the trap was received

11:13:40

3

The IP address of the local MGP

135.8.118.252

4

The Branch Gateway up time

sysUpTime.0 = Timeticks: (43147723) 4 days, 23:51:17.23

5

The trap name, which indicates that this is a QoS trap

snmpTrapOID.0 = OID: av

RtpQoSTrap

6

The local gateway PMI

avRtpSessionLocAddrV4.0 = IpAddress: 135.8.118.252

7

The remote VoIP engine, gateway PMI, or IP phone address

avRtpSessionRemAddrV4.0 = IpAddress: 135.8.76.107

8

The duration of the RTP session

Duration: 00:04:33

9

Format: gwt@<MGP-address>

avRtpSessionCname.0 = STRING: gwp@135.8.118.252

10

The local extension number and conference ID in format <conference ID>:<extension number>.

Conference calls can involve more than one entry in the session table. Multiple sessions belonging to the same conference call can usually be identified by a common conference ID.

Notes:

avRtpSessionPhone.0 = STRING: 69:2011

11

An arbitrary index number for the session in the session table

avRtpSessionDebugStr.0 = STRING: Id{35}

12

The total number of sent traps since the application was enabled

Traps{24¹¹/0}

13

The number of traps that were dropped by the trap rate limiter since the application was enabled. This item can be used, when analyzing received traps logs, to identify missing traps (due to network conditions or the rate limiter). This is also displayed by the show rtp-stat summary command.

Traps{24/0¹²}

14

The number of times the application sampled the VoIP engine (RTP receiver) statistics

Stats{S 54}

15

Stats{S 54 RTCP 54¹⁴ RX 9236}

16

The total number of received RTP packets

Stats{S 54 RTCP 54 RX 9236¹⁵}

17

The codec used for the session

19

The encryption method

encryptionOff

20

21

The transmitted silence suppression method

SSup disabled/disabled²⁰

22

The average of all codec loss values sampled during the session

Loss 0.1%²¹ #1

23

The codec loss event counter

Loss 0.1% #1²²

24

The average of all codec round trip time values sampled during the session

RTT 570mS²³ #38

The average of all network RTP packet loss values sampled during the session

Loss 0.0%²⁷ #0

29

The network RTP packet loss event counter

Loss 0.0% #0²⁸

30

The average of all network RTT values during the session

RTT 376mS²⁹ #38

31

The network RTT event counter

RTT 376mS #38³⁰

32

The network jitter at the RTP receiver

33

The minimum and maximum TTL values sampled in the session

TTL 63-63

34

A counter that increments each time two consecutive RTP packets with the sample RTP sequence number are received

Dup 0

35

A counter that increments each time an RTP packet with a sequence number less than the last known sequence is received

Fall 0

36

The average network loss experienced by the remote RTP receiver

Rem{Loss 0.0%³⁶ #0 Jtr #0}

37

A counter that increments each time the remote loss is sampled over its threshold

Rem{Loss 0.0% #0³⁷ Jtr #0}

38

A counter that increments each time the network jitter experienced by the remote RTP receiver is sampled over its threshold

Rem{Loss 0.0% #0 Jtr #0³⁸}

39

The echo cancellation loss on the TDM bus. A high value (that is, a low absolute value) may indicate impairment of DCP terminals.
