This read-create value configures the NSAP address of the peer endpoint that this connection should reach, forming part of the peer's unique identifier along with the remote VPI and VCI. An admin sets this when manually provisioning a point-to-point SPVC connection to specify the target switch or endpoint address, though it is not meaningful if the connection is configured as point-to-multipoint. For example, when setting up an SPVC to a remote site, the admin enters that site's NSAP address here so the switch knows exactly where to route the connection.
