Note You cannot configure the internally allocated VLANs (reserved VLANs).
VLANs 3968 to 4049 and 4094 are reserved for internal use; these VLANs cannot be changed or used.
Note
Cisco NX-OS allocates a group of 82 VLAN numbers for those features, such as multicast and diagnostics,
that need to use internal VLANs for their operation. By default, the system allocates VLANs numbered 3968
to 4049 for internal use. VLAN 4094 is also reserved for internal use by the switch.
You cannot use, modify, or delete any of the VLANs in the reserved group. You can display the VLANs that
are allocated internally and their associated use.
