tls services are up when the service is administratively up and either at least one SAP or spoke SDP Bind or one mesh SDP Bind is operationally up.
tls service that has vxlan configuration is up when the service is administratively up.
ies services are up when the service is administratively up and at least one interface is operationally up.
