Release Notes for Cisco Network Assistant 5.0 and Later

OL-12210-03

Limitations and Restrictions

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 other than 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)

This limitation applies 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)

Network Assistant Limitations and Restrictions

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

All Devices

These limitations apply to all the devices described in the “Devices Supported” section on page 4:

• 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)

• When the active device fails in a device cluster that uses 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 STP

blocking state. See the "Configuring STP" chapter in the software configuration guide for

information about verifying port status. (CSCec31495)
