Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Release 4.1(3a)
OL-17675-05
Limitations and Restrictions
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 4.1(3a) does not support RSA version 1 keys. As a result, if you
upgrade to NX-OS Release 4.1(3a) 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 Disable SSH.
Step 2 Create RSA version 2 DSA keys.
Step 3 Enable SSH.
Proceed with the upgrade to NX-OS Release 4.1(3a).
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 Issue the no feature ssh command to disable SSH.
Step 3 Issue the ssh key rsa 1024 command to create RSA version 2 keys.
Step 4 Issue the feature ssh command to enable SSH.
CFS Cannot Distribute All CallHome Information
In MDS NX-OS Release 4.1(3a), CFS cannot distribute the following CallHome commands that can be
configured with the destination-profile command:
• destination-profile profile_name transport-method
• destination-profile profile_name http
The output of the show running-config callhome command shows configured CallHome commands:
