absolutely guarantee that a switch that requests to be the principal switch will actually achieve that status. NOTE: The fabricprincipal command is available with Fabric OS version 4.1.0 or later. The primary management switch is used by Fabric Manager as the main access point to that fabric. • Fabric time synchronization is available with Fabric OS versions 2.6.1, 3.1, and 4.1 or later. Switches in a fabric where security is not enabled synchronize time with the principal switch in the fabric. The principal switch in the fabric synchronizes its clock with an NTP time server by identifying the time server with the tsclockserver command. In a fabric where security is nl enabled, switches synchronize time with the primary Fibre Channel switch, which may or may not be the principal switch. B-series FCoE Converged Network switch This section describes support for B-series FCoE CN switches, switch model, and FCoE fabric rules. For more information on configuring FCoE SANs, see the HP StorageWorks Fibre Channel over Ethernet application note, available at http://www.hp.com/go/SDGmanuals. NOTE: The naming scheme for the HP StorageWorks 2408 Converged Network Switch, which has 24 CEE ports and 8 Fibre Channel ports, is slightly different from the typical B-series switch naming scheme. Table 36 describes the B-series FCoE CN switch.
