22 Release and Migration Notes - Updating Standard Hardware from 4.2.x to 5.0.3

Step 2: Generate the Mapping Data

Log-in to the unit via ssh as root and issue the following command:
CreateMACMapping

Running this program multiple times will do no harm.

Copy the output lines of the program beginning with CM and those beginning

with CI to the clipboard.

Step 3: Apply the Mapping Data

On standalone units, open the

Box Network Configuration

within Barracuda NG

Admin.
On NG CC-managed units, open the

Box Network Configuration

within Barracuda

NG Admin on the respective Barracuda NG Control Center.

Paste the content of the clipboard to

Network > Interfaces > MAC Mapping

(only

visible in

Advanced

configuration mode).

Step 4: Proceed to the Update

Upgrade the unit following the standard 5.0.3 upgrade procedure as described
in

Determine Your Update Scenario

, page 13.

When the update process is finished, please verify if all interfaces are correctly mapped.

In case the linux kernel 2.4 assigned the interfaces in the same order as the linux kernel 2.6 did, the following
message will be generated into the 5.0.x box network activation log:
No difference found between configured and detected MAC to interface mapping

In this case you may disable MAC mapping. This will make the configuration hardware-independent, providing you
with more flexibility in case hardware will be changed somewhen in the future.

Further advice about updating standard hardware is available through the Barracuda Networks support.
