NOTE:

The VSA does not support changing the speed and duplex settings.

Requirements

These settings must be configured before creating NIC bonds.

If you change these settings, you must ensure that both sides of the NIC cable are configured
in the same manner. For example, if the storage system is set for Auto/Auto, the switch must
be set the same.

If you edit the speed or duplex on a disabled or failed NIC, the new setting will not be applied
until the NIC is enabled or connectivity is restored.

Best practice

Change the speed and duplex settings while the storage system is in the Available Systems pool
and not in a management group.

To change the speed and duplex

1.

In the navigation window, select the storage system and log in.

2.

Open the tree, and select TCP/IP Network.

3.

Select the TCP Status tab in the tab window.

4.

Select the interface to edit.

5.

Click TCP/IP Status Tasks, and select Edit.

6.

Select the combination of speed and duplex that you want.

7.

Click OK.

A series of status messages appears. Then the changed setting appears in the TCP status
report.

NOTE:

You can also use the Configuration Interface to edit the TCP speed and duplex. See

“Setting the TCP speed, duplex, and frame size” (page 237)

.

Changing NIC frame size

Network frame size affects management data traffic and replication. Use the same network frame
size in all storage systems in a cluster to ensure consistent data traffic and replication.

Best practices

Change the frame size while the storage system is in the Available Systems pool and not in a
management group.

The frame size specifies the size of data packets that are transferred over the network. The default
Ethernet standard frame size is 1500 bytes. The maximum allowed frame size is 9000 bytes.

Increasing the frame size improves data transfer speed by allowing larger packets to be transferred
over the network and by decreasing the CPU processing time required to transfer data. However,
