Configuring Port Speed

Restrictions

• Changing port speed and rate mode disrupts traffic on the port. Traffic on other ports in the port group is not affected.

Detailed Steps

To configure dedicated bandwidth on an interface using DCNM-SAN, follow these steps:

1. From the Fabric pane, select a switch or select a group of switches (SAN, fabric, VSAN) from the Logical Domains pane.
2. Expand Switches, expand FC Interfaces and select Physical from the Physical Attributes pane.

You see the Physical > General tab in the Interfaces pane.

3. Scroll until you see the row containing the switch and port you want to configure.
4. Select auto, 1Gb, 4Gb, or autoMax2G from the Speed Admin column.

Note     The Generation 3, 8-Gbps Fibre Channel switching modules support the following speed configurations: 1G, 2G, 4G, 8G, autoMax2G, autoMax4G and the auto speed configuration configures autosensing for the interface with 8 Gbps of bandwidth reserved.

The auto parameter enables autosensing on the interface. The autoMax2G parameter enables autosensing on the interface with a maximum speed of 2 Gbps.

Note     If you change the port bandwidth reservation parameters on a 48-port or 24-port 4-Gbps, or any 8-Gbps Fibre Channel switching module, the change affects only the changed port. No other ports in the port group are affected.

5. Click the Apply Changes icon.
