VC Tester Vcfr Segments Sent
1.3.6.1.4.1.562.2.4.1.5130.5.11.1.4
This attribute displays the number of segments sent at the time command was issued. This is the segment sent count maintained by accounting at the source Vc. Vc only counts packets that Vc thinks can be delivered successfully into the subnet. In reality, these packets may be dropped by trunking, for instance. This counter is not updated when splitting fails, when Vc is in a path recovery state, when packet forwarding fails to forward this packet and when subsequent packets have to be discarded as we want to minimize the chance of out-of-sequence and do not intentionally send out-of- sequenced packets into the subnet.
