sdlcLSStatsRetransmits
Module: A3COM-SDLC-R1-MIB
OID (symbolic): A3COM-SDLC-R1-MIB::sdlcLSStatsRetransmits
OID (numeric): 1.3.6.1.4.1.43.2.25.2.3.1.11
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: This object reflects the total number of information frames retransmitted to a remote link station because the N(r) received from that link station indicated that one or more information frames sent to 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 sdlcLSStatsRetransmits grows over time, then the quality of the serial line is in question. You might want to look at decreasing the value for sdlcLSAdminMAXDATA to compensate for the lower quality line.
What is sdlcLSStatsRetransmits?
Counts information frames resent because the remote didn't acknowledge the original, indicating packet loss or timeouts. High retransmit counts signal link quality problems. 300 retransmits against 5,000 sent frames suggests 6% loss, indicating poor line quality.
