esaReflectorAlias is a read-create DisplayString (up to 128 characters) letting a management application attach a human-readable label to an ESA Reflector. An administrator uses it to give a reflector a meaningful name such as a site or customer identifier, since the reflector's own name field is capped at 15 characters and may not be descriptive enough on its own. For example, setting this alias to a full customer site description lets a technician browsing a long reflector list immediately recognize which physical location a cryptic 15-character reflector name actually refers to.
