sdlcLSStatsRetransmitsIn
Module: SNA-SDLC-MIB
OID (symbolic): SNA-SDLC-MIB::sdlcLSStatsRetransmitsIn
OID (numeric): 1.3.6.1.2.1.41.1.2.3.1.39
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: This object reflects the total number of information frames retransmitted by the remote link station because the N(s) received from that link station indicated that one or more information frames sent by that station were lost. This event causes the first missing information frame of a window and all subsequent information frames to be retransmitted. At link station startup time, this object must be initialized to zero.
Management: If the value of sdlcLSStatsRetransmitsIn grows over time, then the quality of the serial line is in question. You might want to look at decreasing the value for sdlcLSAdminMAXDATASend to compensate for the lower quality line.
What is sdlcLSStatsRetransmitsIn?
This counter, reset to zero at link station startup, tracks I-frames the remote link station had to retransmit because it detected (via N(s)) that frames it sent were lost; the MIB itself notes that a growing value here points to poor serial line quality and suggests lowering sdlcLSAdminMAXDATASend to compensate.
