Limitations and Restrictions Send documentation comments to [email protected] 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(1a) does not support RSA version 1 keys. As a result, if you upgrade to NX-OS Release 4.2(1a) 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: Step 1 Step 2 Step 3 Step 4 Disable SSH. Create RSA version 2 DSA keys. Enable SSH. 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(1a). If you upgrade before disabling SSH and creating RSA version 2 keys, follow these steps: Step 1 Step 2 Step 3 Step 4 Open a Telnet session and log in through the console. Issue the no feature ssh command to disable SSH. Issue the ssh key rsa 1024 command to create RSA version 2 keys. Issue the feature ssh command to enable SSH.
