vSphere PortMirror: What does "Source/Destination" mean as in "Remote Mirroring Source" and "Remote Mirroring Destination"?

The following is from vSphere's admin doc:

To begin a port mirroring session, you must specify the type of port mirroring session.

Procedure

  1. Browse to a distributed switch in the vSphere Client navigator.

  2. Click the Configure tab and expand Settings.

  3. Select the Port mirroring option and click New.

  4. Select the session type for the port mirroring session.

    Option Description
    Distributed Port Mirroring Mirror packets from a number of distributed ports to other distributed ports on the same host. If the source and the destination are on different hosts, this session type does not function.
    Remote Mirroring Source Mirror packets from a number of distributed ports to specific uplink ports on the corresponding host.
    Remote Mirroring Destination Mirror packets from a number of VLANs to distributed ports.
    Encapsulated Remote Mirroring (L3) Source Mirror packets from a number of distributed ports to the IP addresses of a remote agent. The virtual machine’s traffic is mirrored to a remote physical destination through an IP tunnel.
  5. Click Next.

Every time I read this part I would be confused. I could never relate the word "Source" and "Destination" to what it says in the Description and so I could never remember who's who.

Sorry, to be clear, you're asking what it means by source and destination when talking about port mirroring?

@Chopper3 not when generally talking about port mirror, but when saying the terminology "Remote Mirroring Source" and "Remote Mirroring Destination" as in vsphere's doc.

for example when we talk about "src ip" or "dest ip", src/dest just literally means src/dest. it's very straightforward and takes nothing to understand.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
