Symptom: Using Fabric Manager Web Client, you download Fabric Manager Client and when
prompted to create a desktop shortcut, you select Yes. The default shortcut named "Cisco Fabric
Manager" is created on the desktop. Then, using Fabric Manager Web Client again, you download
another Fabric Manager Client from a different server (usually this will be a different version of
Fabric Manager Client). You will not be prompted to create another shortcut because a desktop
shortcut titled "Cisco Fabric Manager" already exists from the first installation.
Workaround. To create multiple Fabric Manager Client desktop shortcuts with unique names,
follow these steps:
From Start > Control Panel > Java > Temporary Internet Files > click View. The Java Cache
1.
Viewer is launched.
2. Right-click one of the versions of Fabric Manager Client and select Install Shortcuts from the
drop down menu. The shortcut is created on the desktop.
3. Change the name of the new shortcut.
4. Repeat steps 2 and 3 for each additional Fabric Manager Client.

Symptom: Flow statistics on a Generation 2 module may not be accurate if any of the flows that
participate in flow statistics on the module have multiple FSPF paths.
Workaround: For all flows that have flow statistics configured on that module, make sure there is
only one available FSPF path. Use PortChannel instead of multiple links to achieve more bandwidth.

Symptom: In rare cases, following a downgrade from an NX-OS 4.x image to a SAN-OS 3.x image,
the available space on the bootflash might be displayed as less than the actual space that is available.
Workaround: Before downgrading from an NX-OS 4.x image to a SAN-OS 3.x image, enter the
system health check bootflash command, which is available starting in NX-OS 4.1(1b), to ensure
that the available free space is taken into account properly. The following example shows this
command and its output:
switch# system health check bootflash
NOTE: This command can take over 30 minutes. Bootflash will be offline during th
is time.
Do you want to continue? (yes/no)
Although the switch indicates that the bootflash check takes 30 minutes, it typically completes in
just a few seconds.
Once the bootflash check is complete, you can proceed with the downgrade process.
If you are downgrading an MDS 9500 Series switch, you must enter the system health check
bootflash command on both the active supervisor and the standby supervisor. You will need to
enter the show module command to determine the standby module and then attach to that
module by entering the attach module command. For detailed instructions, see the
"Downgrading from NX-OS 4.x to SAN-OS 3.x" section on page
