[cashqoo]

i am using the following Cisco URL as reference.

Source: http://www.cisco.com/en/US/docs/ios/12_4/ip_sla/configuration/guide/hsjitter.html

1. is there a difference IP SLA and RTR commands, and can they work with one another?

2. referring to the rttmon mib/oib, which exact OID should i use to obtain the average values for the following?

   a) delay(RTT)

    i dont find any OID for avg. the nearest OID

    - rttMonLatestJitterOperNumOfRTT    1.3.6.1.4.1.9.9.42.1.5.2.1.1

    - rttMonLatestJitterOperRTTSum    1.3.6.1.4.1.9.9.42.1.5.2.1.2

   b) jitter

    - rttMonLatestJitterOperAvgJitter    1.3.6.1.4.1.9.9.42.1.5.2.1.46 (is this correct?)

   c) packet loss

    i dont find any OID for avg packet loss. the nearest OID

    - rttMonLatestJitterOperPacketLossSD    1.3.6.1.4.1.9.9.42.1.5.2.1.26
