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

http

The output of the

show running-config callhome

command shows configured CallHome commands:
