Module: Nortel-MsCarrier-MscPassport-VcTesterMIB
OID (symbolic): Nortel-MsCarrier-MscPassport-VcTesterMIB::mscVctVcOutOfRangeFrmFromSubnet
OID (numeric): 1.3.6.1.4.1.562.36.2.1.5130.4.12.1.2
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: This attribute counts the number of subnet frames discarded due to the sequence number being out of range. Two Categories apply for the General Vc 1) lost Acks (previous Range) 2) unexpected Packets (next Range) Vc internally maintains its own sequence number of packet order and sequencing. Due to packet retransmission, Vc may receive duplicate packets that have the same Vc internal sequence number. Only 1 copy is accepted by the Vc and other copies of the same packets are detected through this count. This attribute can be used to record the frequency of packet retransmission due to Vc and other part of the subnet.
What is mscVctVcOutOfRangeFrmFromSubnet?
Counts subnet frames this Vc discarded because their sequence number fell outside the expected range (covering both lost acks and unexpected packets); a rising count signals frequent packet retransmission somewhere in the subnet path.
