cnt2TransportRexmit
Module: CNT246-MIB
OID (symbolic): CNT246-MIB::cnt2TransportRexmit
OID (numeric): 1.3.6.1.4.1.333.2.4.6.1.1.21
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The number of packets being retransmitted
What is cnt2TransportRexmit?
This Counter32 counts the number of packets that had to be retransmitted on this transport connection. A climbing retransmit count points to packet loss or congestion on the path between the two CNT nodes, which an admin would want to correlate with link errors or bandwidth saturation. For example, a sudden spike in cnt2TransportRexmit during a backup job could indicate the WAN circuit is being overrun.
