This read-write integer configures the VPI value expected from the remote end point (the CPE at the far side of the connection), functioning similarly to a connection identifier and not necessarily matching any locally used VPI value. Admins set this when provisioning a connection to specify what VPI the remote CPE will be using, which the switch needs to know to correctly route or validate the connection. For example, an admin setting up a connection to a remote CPE that's configured for VPI 5 would set ausmRemoteVpi to 5 so the switch expects and correctly interprets traffic tagged with that value from the far end.
