Configuring Bandwidth Fairness

As of Cisco SAN-OS Release 3.1(2) and later, all 48-port and 24-port 4-Gbps Fibre Channel switching
modules, as well as 18-port Fibre Channel/4-port GigabitEthernet Multiservice modules, have
bandwidth fairness enabled by default, which improves fairness of bandwidth allocation among all ports
and provides better throughput average to individual data streams. Bandwidth fairness can be configured
per module.
When you disable or enable bandwidth fairness, the change does not take effect until you reload the

module.
Note This feature is only supported onthe 48-port and 24-port 4-Gbps Fibre Channel switching modules, as
well as the 18-port Fibre Channel/4-port GigabitEthernet Multiservice module.

Enabling Bandwidth Fairness

To enable bandwidth fairness on multiple 48-port or 24-port 4-Gbps Fibre Channel switching modules
using Device Manager, follow these steps:
Step 1 Choose Physical > Modules.
You see the Module dialog box as shown in
Figure 22-10
