copyAlarmIndex is a notification varbind identifying which f10CopyTable row, via its copyConfigIndex, the alarm trap relates to, or -1 if the copy was run from the CLI instead of SNMP, per its description. An admin uses this to correlate an incoming copy-alarm trap with the specific SNMP-initiated copy job in f10CopyTable, or to recognize that a CLI-driven copy triggered the alarm when the value is -1. For example, a trap with copyAlarmIndex of 3 tells an admin to look at row 3 of f10CopyTable for the copyState and copyFailCause of the job that generated the alarm, whereas a value of -1 means no such row exists because it was a CLI copy.
