The Ethernet interface on your switch

Enabling DHCP after the Ethernet information has been configured releases the current Ethernet

network interface settings, including Ethernet IP, Ethernet Subnetmask, and Gateway. The Fibre

Channel (FC) IP address and subnet mask are static and are not affected by DHCP; see “Static

Ethernet addresses” on page 8 for instructions on setting the FC IP address.

1. Connect to the switch and log in using an account assigned to the admin role.

2. Enter the ipAddrSet command.

3. If already set up, skip the Ethernet IP address, Ethernet subnet mask, Fibre Channel IP

address and subnet mask prompts by pressing Enter.

4. When you are prompted for DHCP[Off], enable it by entering on.

Example of enabling DCHP.

switch:admin> ipaddrset

Ethernet IP Address [10.1.2.3]:

Ethernet Subnetmask [255.255.255.0]:

Fibre Channel IP Address [220.220.220.2]:

Fibre Channel Subnetmask [255.255.0.0]:

Gateway IP Address [10.1.2.1]:

DHCP [Off]:on

Deactivating DHCP

When you disable DHCP, enter the static Ethernet IP address and subnet mask of the switch and

default gateway address. Otherwise, the Ethernet settings may conflict with other addresses

assigned by the DHCP server on the network.

1. Connect to the switch and log in using an account assigned to the admin role.

2. Enter the ipAddrSet command.

3. Enter the network information in dotted-decimal notation for the Ethernet IPv4 address and in

semicolon-separated notation for IPv6.

If a static Ethernet address is not available when you disable DHCP, enter 0.0.0.0 at the

Ethernet IP address prompt.

4. Skip Fibre Channel prompts by pressing Enter.

5. When you are prompted for DHCP[On], disable it by entering off.
