Reserved VSAN Range and Isolated VSAN Range Guidelines On an NPV switch with a trunking configuration on any interface, or on a regular switch where the feature fport_channel_trunk command has been issued to enable the Trunking F PortChannels feature, follow these configuration guidelines for reserved VSANs and the isolated VSAN: • If trunk mode is on for any of the interfaces or NP PortChannel is up, the reserved VSANs are 3040 to 4078, and they are not available for user configuration. • The Exchange Virtual Fabric Protocol (EVFP) isolated VSAN is 4079, and it is not available for user configuration. • VSAN 4079 will be impacted by an upgrade to NX-OS Release 4.1(3a), depending on whether or not VSAN 4079 was created prior to the upgrade. See the "Upgrading Effect on VSAN 4079" section on page 19 for details. The following VSAN IDs are assigned in the Fibre Channel Framing and Signaling (FC-FS) interface standard: VF_ID Value 00h 001h ... EFFh F00h ... FEEh FEFh FF0h ... FFEh FFFh FEFh = 4079 Value Description Do not use as a Virtual Fabric Identifier. Available as a Virtual Fabric Identifier. Reserved. Control VF-ID (see Fibre Channel Link Services (FC-LS) and Fibre Channel Switch Fabric Generation 4 (FC-SW-4) standards). Vendor specific. Do not use as a Virtual Fabric Identifier.
