Like its address-type sibling, this field is explicitly a display-purposes duplicate of cienaCesExtAclEntrySrcInetAddr, carrying the actual source network address being authorized directly inside this extended-ACL notification trap rather than requiring the receiver to separately query the base table. An admin's SIEM or audit log captures this value at the moment the notification fires as the historical record of what source address was authorized in this extended ACL entry, self-contained within the trap itself. For example, a security audit trail built purely from these notification traps can reconstruct the full history of authorized extended-ACL source addresses over time without needing continuous polling of the live configuration table.
