Configuring the MTU Frame Size

You can configure the interfaces on a switch to transfer large (or jumbo) frames on a port. The default IP maximum transmission unit (MTU) frame size is 1500 bytes for all Ethernet ports. By configuring jumbo frames on a port, the MTU size can be increased up to 9000 bytes.

Note     The minimum MTU size is 576 bytes.

Tip     MTU changes are disruptive, all FCIP links and iSCSI sessions flap when the software detects a change in the MTU size.

Detailed Steps

To configure the MTU frame size, follow these steps:

  1. Expand Switches > Interfaces > Ethernet > IPS.

    2. You see the Gigabit Ethernet Configuration in the Information pane.

  2. In the General tab, in the Mtu column, you can enter a new value to configure the MTU Frame Size for a specific switch. For example 3000 bytes. The default is 1500 bytes.
  3. Click Apply Changes.
