IPv6 The management port on Cisco MDS switches supports one user-configured IPv6 address, but does not support auto-configuration of an IPv6 address. User Roles In SAN-OS Release 3.3(x) and earlier, when a user belongs to a role which has a VSAN policy set to Deny and the role allows access to a specific set of VSANs (for example, 1 through 10), the user is restricted from performing the configuration, clear, execute, and debug commands which had a VSAN parameter outside this specified set. Beginning with NX-OS Release 4.1(1b), these users are still prevented from performing configuration, clear, execute, and debug commands as before, however, they are allowed to perform show commands for all VSANs. The ability to execute the show command addresses the following: • In a network environment, users often need to view information in other VSANs even though they do not have permission to modify configurations in those VSANs. • This behavior makes Cisco MDS 9000 Series switches consistent with other Cisco products, such as Cisco Nexus 7000 Series switches, that exhibit the same behavior for those roles (when they apply to the VLAN policy).
