# Configuring Ethernet ports

Use this action to configure the Ethernet settings for the controllers in an enclosure. For iSCSI initiators, you can configure three ports per controller: the management port and two iSCSI ports. For fibre channel initiators, you can configure the management port for each controller.

For the management port (iSCSI or fibre channel), you can configure the port link speed. For iSCSI ports, you can configure network settings, such as Maximum Transfer Unit (MTU), TCP/IP address, and subnet mask. If your network uses dynamic IP addresses, you can enable DHCP.

## Configuring the management port

To configure the management port:

1. In the Physical devices view, click a controller in the enclosure.

   Note: Be sure to switch to enclosure view first!

2. Right click Configure ethernet port ETH 0 (management). The "Configure Ethernet port" window opens.
3. From the Link speed drop-down list, select the port link speed, in megabytes. To automatically detect the link speed (1 GB or less), select AUTO.
4. Click OK.

## Configuring iSCSI ports (iSCSI initiators only)

To configure the iSCSI ports:

1. In the Physical devices view, click a controller in the enclosure.

   Note: Be sure to switch to enclosure view first!

2. Right click Configure ethernet port ETH 2 (iscsi) or ETH 3 (iscsi). The "Configure Ethernet port" window opens.
3. From the Link speed drop-down list, select the port link speed, in megabytes, as described above.
4. From the Maximum transmission unit drop-down list, select the MTU packet size, in megabytes; either 1500 MB or 9000 MB.
5. If your network uses dynamic IP addresses, click DHCP; then, skip to step 9.
6. In the IP address field, enter the iSCSI port's TCP/IP address.
7. In the Subnet mask field, enter the TCP/IP number of the device's TCP/IP subnet.
8. (optional) In the Broadcast address field, enter the TCP/IP address for sending messages to machines on the network.
9. Click OK.
