What is slAlarmIfIndex?

This read-only value is the interface index this alarm entry corresponds to, where the interface type may be a Sonet Line, Sonet Path, CLU, or NE. An admin uses this to identify exactly which SONET-related interface or logical entity a given alarm applies to. For example, this object pointing to a Sonet Path interface would tell the admin the alarm concerns that logical path rather than the underlying physical Sonet Line.
