Port speed
Port speed is the maximum amount of data that can pass through the port at a given second. The
unit of measurement is in gigabits per second (Gbps).
NOTE
For the 10 Gbps CNA, the only option is auto-negotiate.

Configuring the port speed using the GUI

1. Select Configure > Basic Port Configuration from the Host Connectivity Manager.
The Basic Port Configuration dialog box displays.
2. Select a value from the Configured Speed list.
Speed options for the HBA are 1 Gbps, 2 Gbps, 4 Gbps, and 8 Gbps. The available speed
options depend on the HBA’s speed and the port’s SFP. Auto-negotiate is the recommended
setting and it is the default.
3. Click Apply to apply the changes.
A port disable/enable configuration dialog displays, confirming the configured speed, which
will take effect when the port is disabled or enabled.
4. Click Yes to continue, or No to cancel the operation.
5. Click OK to close the window.

Configuring the port speed using the BCU

Enter the following command to set the port speed.
bcu port - -speed <port_id> [<speed>]
Refer to “port” on page 185 for details about this command.
