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.
