Limitations and Restrictions
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, we recommend 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
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, 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 an RSA version 1 key for SSH, then you will not be able to log in through SSH following
the upgrade.
If you have an RSA version 1 key configured for SSH, before upgrading to NX-OS Release 4.1(3a),
follow these steps:
Step 1 Disable SSH.
Step 2 Create RSA version 2 DSA keys.
Step 3 Enable SSH.
Step 4 Delete any RSA version 1 keys on any remote SSH clients and replace the version 1 keys with the new
version 2 keys from the switch.
Proceed with the upgrade to NX-OS Release 4.2(1b).
If you upgrade before disabling SSH and creating RSA version 2 keys, follow these steps:
Step 1 Open a Telnet session and log in through the console.
Step 2 Use the no feature ssh command to disable SSH.
Step 3 Use the ssh key rsa 1024 command to create RSA version 2 keys.
