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.
InterVSAN Routing
When using InterVSAN Routing (IVR), it is recommended to enable Cisco Fabric Services (CFS) on all
IVR-enabled switches. Failure to do so may cause mismatched active zone sets if an error occurs during
zone set activation.
Java Web Start
When using Java Web Start, it is recommended that you do not use an HTML cache or proxy server. You
can use the Java Web Start Preferences panel to view or edit the proxy configuration. To do this, launch
the Application Manager, either by clicking the desktop icon (Microsoft Windows), or type ./javaws in
the Java Web Start installation directory (Solaris Operating Environment and Linux), and then select
Edit> Preferences.
If you fail to change these settings, you may encounter installation issues regarding a version mismatch.
If this occurs, you should clear your Java cache and retry.
VRRP Availability
The Virtual Router Redundancy Protocol (VRRP) is not available on the Gigabit Ethernet interfaces on
the MSM-18/4 module or module 1 of the MDS 9222i switch, even though it is visible on these modules.
The feature is not implemented in the current release.
Using a RSA Version 1 Key for SSH Following an Upgrade
For security reasons, NX-OS Release 4.2(1b) does not support RSA version 1 keys. As a result, if you
upgrade to NX-OS Release 4.2(1b) from an earlier version that did support RSA version 1 keys, and you
had configured a RSA version 1 key for SSH, then you will not be able to log in through SSH following
the upgrade.
If you have a RSA version 1 key configured for SSH, before upgrading to NX-OS Release 4.1(3a), follow
these steps:
