This read-create value configures the routing priority of the connection, defaulting to 8 if not specified, and cannot be set on a slave endpoint since any attempt to change it there is rejected. An admin adjusts this on the master endpoint to influence how the switch's routing algorithm favors this connection relative to others when selecting or rerouting paths through the network. For example, for a critical SPVC that should be rerouted ahead of less important connections during a network failure, the admin, on the master endpoint, would set a higher routing priority than the default of 8.
