Module: COSINE-ORION-MIB
OID (symbolic): COSINE-ORION-MIB::csOrionVPNVRouterTcpRetransSegs
OID (numeric): 1.3.6.1.4.1.3085.3.1.4.2.6.1.1.12
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: The total number of segments retransmitted - that is, the number of TCP segments transmitted containing one or more previously transmitted octets.
What is csOrionVPNVRouterTcpRetransSegs?
This counter tracks the total number of TCP segments retransmitted by this virtual router, meaning segments carrying one or more previously sent octets. A high or fast-growing value is a classic sign of packet loss or congestion on links used by this virtual router, prompting an admin to check underlying circuit quality. For example, an admin notices csOrionVPNVRouterTcpRetransSegs climbing sharply right after a Frame Relay circuit supporting this VR started experiencing frame drops, confirming the retransmissions are a symptom of the underlying link problem.
