This object sets the severity level assigned to the interface's Loss of Signal alarm and controls whether an SNMP trap is generated when that alarm's status changes. Admins tune this per interface to prioritize alarm handling, assigning higher severity to critical trunk links and lower severity or trap-disabled to less important ports, so the alarm dashboard reflects real operational impact. For example, an admin might leave the default major-trap-enable setting on a primary backhaul radio so a lost signal there immediately generates a major-severity trap, while lowering severity on a redundant standby link.
