Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 5.2(2)
OL-25090-02
Limitations and Restrictions
• PPRC Not Supported with FCIP Write Acceleration, page 34
• Configuring a Persistent FCID in an IVR Configuration with Brocade Switches, page 34
FCoE Module
• In Cisco MDS NX-OS Release 5.2(x), you cannot install a FCoE module in a switch that is running
DMM, SME, or IOA.
• Link traps for FCoE devices are sent only when a VFC interface flaps.
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).
Schedule Job Configurations
As of MDS NX-OS Release 4.1(1b) and later, the scheduler job configurations need to be entered in a
single line with a semicolon(;) as the delimiter.
Job configuration files created with SAN-OS Release 3.3(1c) and earlier, are not supported. However,
you can edit the job configuration file and add the delimiter to support Cisco NX-OS Release 4.1(3a).
Maximum Number of Zones Supported in Interop Mode 4
In interop mode 4, the maximum number of zones that is supported in an active zone set is 2047, due to
limitations in the connected vendor switch.
When IVR is used in interop mode 4, the maximum number of zones supported, including IVR zones,
in the active zone set is 2047.
