WAN Rate Upgrade 2 License – The WAN Rate Upgrade 2 license provides unlimited WAN throughput (other
than the hardware limit) on Brocade 7840. The WAN Rate Upgrade 2 licenses also enable the use of two
40GbE ports on Brocade 7840. The 40GbE ports cannot be configured without the WAN Rate Upgrade 2
license. A WAN Rate Upgrade 1 license must be installed on a Brocade 7840 before a WAN Rate Upgrade 2
license is installed. A WAN Rate Upgrade 1 license cannot be removed before the WAN Rate Upgrade 2 license
has been removed.
Note: The WAN Rate Upgrade 1 and WAN Rate Upgrade 2 licenses apply only to Brocade 7840. They
control the aggregate bandwith for all tunnels on a Brocade 7840. The entire capacity controlled by
the licenses can be assigned to a single tunnel subject to hardware limitation, or a portion of the
capacity can be assigned to multiple tunnels. The total bandwidth aggregated for all tunnels should
not exceed the limits established by the licenses.
