Cisco Cisco Network Assistant Version 4.0

This limitation applies only to the Catalyst 4500 series and Catalyst 3750, 3560, 3550, and 2970 
switches:

If a Catalyst 2900 XL or 3500 XL cluster command device is connected to a Catalyst 3550 or a 3750 
switch, the command device does not find any cluster candidates beyond the 3550 or the 3750 switch 
candidates. You must add the 3550 or the 3750 switch to the cluster to see other cluster candidates. 
(CSCdt09918)

These limitations apply only to the Catalyst 3750, 3560, 3550, and 2970 switches:

If both the active command device and the standby command device fail at the same time, the cluster 
is not automatically recreated. Even if there is a third passive command device, it might not recreate 
all cluster members because it might not have all the latest cluster configuration information. You 
must manually recreate the cluster if both the active and standby command devices simultaneously 
fail. (CSCdt43501) 

When the active device fails in a device cluster that uses Hot Standby Routing Protocol (HSRP) 
redundancy, the new active device might not contain a full cluster member list.

The workaround is to ensure that the ports on the standby cluster members are not in the Spanning 
Tree Protocol (STP) blocking state. See the "Configuring STP" chapter in the software configuration 
guide for more information about verifying port status. (CSCec31495) 

These limitations apply only to the Catalyst 2955, 2950, and 2940 switches:

When a cluster of devices have Network Time Protocol (NTP) configured, the command device is 
not synchronized with the rest of the devices. (CSCdz88305)

The Network Assistant limitations and restrictions are described in these sections.

These limitations apply to all the devices described in the 

CNA supports the standard ASCII character set. Do not enter characters from extended ASCII character 
sets in GUI fields for feature options.

A red border appears around the text-entering area of some Network Assistant windows. The color 
of the border changes to green when text is entered. The colored border does not prevent you from 
entering text. (CSCdv82352)

You cannot switch modes (for example, from guide mode to expert mode) for an open Network 
Assistant window. The workaround is to close the open window, select the mode that you want, and 
then reopen the Network Assistant window. For the mode change to take effect on any other Network 
Assistant window that is open, you need to close that window and then reopen it after you select the 
new mode. (CSCdw87550)

If you open a window in which you can enter text, open another window, and return to the first 
window, right-clicking in the text field might make the cursor in this field disappear. You can still 
enter text in the field. (CSCdy44189)

If you select multiple ports and open the Port Settings window from the popup menu of the Front 
Panel view, it might take approximately 7 seconds to open.

The workaround is to open the Port Settings window from the feature bar. (CSCee96650)
