NGY 10GBASE-T Port Properties–LASI

The Link Alarm Status Interrupt (LASI) is an active-low output from the 10GBASE-T adapter that indicates a link fault condition has been asserted or has been cleared. Control registers are provided so that LASI may be programmed to assert only for specific fault conditions.

For more detailed information on LASI, see the Link Alarm Status Interrupt (LASI) section in the ‘Theory of Operation: General’ chapter of the Ixia Platform Reference Manual.

The LASI tab page is shown in Image: 10GBASE-T LASI Configuration.
