Ephemeral normally refers to the source port used by a TCP client to connect to a server. Here's a Wikipedia link; http://en.wikipedia.org/wiki/Ephemeral_port. I'm not sure how this relates to SNMP and the items above, it's rather confusing to be honest.
mhite_60883Same boat. I just don't understand what the heck it means in relation to virtual server connections...

this is what i found from the past case which was answered by Jeffrey Hafey. he is one of the best engineers i know.
Ephemeral listeners are short-lived listeners which are created generally by a control channel in order to handle response traffic (e.g., FTP, RTSP).
hope this helps.- mhite_60883AH, OK, so if the Virtual Server type is something that has a separate return channel. Got it. Thanks!
