NOTE:
You can also use the Configuration Interface to edit the frame size.

Changing NIC flow control

You can enable flow control on the NICs to prevent data transmission overruns that result in packets
being dropped. With flow-control enabled, network packets that would otherwise be dropped will
not have to be retransmitted.
NOTE:
The VSA does not support changing flow control settings.

Requirements

• These settings must be configured before creating NIC bonds.
• All NICs should have (or must have, if they are bonded) the same flow control settings.
• Flow control cannot be changed when the port is disabled.

Enabling NIC flow control

To enable NIC flow control:
1. In the navigation window, select a storage system, and log in.
2. Open the tree, and select the TCP/IP Network category.
3. Select the TCP Status tab.
4. Select the interface you want to edit.
5. Click TCP Status Tasks, and select Edit.
6. Select On to enable the flow control on the NIC.
7. Click OK.
8. Repeat Step 4
When you have enabled flow control on both NICs and then you bond those NICs, the NIC flow
control column shows the physical NICs as enabled and the bond0 as disabled. However, flow control
is enabled and working in this case.
