Support for Generation One Modules

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).
