MSTLINK(1) User Commands MSTLINK(1) NAME mstlink - check and debug link status and issues related to them SYNOPSIS mstlink [OPTIONS] DESCRIPTION The mlxlink tool is used to check and debug link status and issues related to them. The tool can be used on different links and cables (passive, ac- tive, transceiver and backplane).
