Configuring DHCP
By default, some HP switches have DHCP enabled. SAN Director 2/128 and 4/256 SAN Director models
do not support DHCP.
The Fabric OS DHCP client supports the following parameters:
•
External Ethernet port IP addresses and subnet masks
•
Default gateway IP address
The DHCP client uses a DHCP vendor class identifier that allows DHCP servers to determine that the
Discovers and Requests are coming from an HP switch. The vendor class identifier is the string "BROCADE"
followed by the SWBD model number of the platform. For example, the vendor class identifier for a request
from a SAN Switch 2/32 (Brocade 3900) is "BROCADESWBD12."
NOTE:
The client conforms to the latest IETF Draft Standard RFCs for IPv4 DHCP.
DHCP summary
Plug DHCP enabled switches in to the network, power on the switch, and the switch automatically obtains
the Ethernet IP address, Ethernet subnet mask, and default gateway address from the DHCP server. The
DHCP client can only connect to a DHCP server on the same subnet as the switch. Do not enable DHCP, if
the DHCP server is not on the same subnet as the 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 is static and is not affected by DHCP, see
Ethernet network
How to enable DHCP
1.
Connect to the switch and log in as admin.
2.
Enter the following command:
switch:admin> ipaddrset
Ethernet IP Address [192.168.74.102]:
Ethernet Subnetmask [255.255.255.0]:
Fibre Channel IP Address [220.220.220.2]:
Fibre Channel Subnetmask [255.255.0.0]:
Gateway IP Address [192.168.74.1]:
DHCP [Off]:on
Skip the Ethernet IP address, Ethernet Subnetmask, Fibre Channel IP address and subnet mask prompts by
pressing enter. For DHCP[Off], enable it by entering On.
How to disable 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 as admin.
2.
Enter the following command:
switch:admin> ipaddrset
Ethernet IP Address [192.168.74.102]:
Ethernet Subnetmask [255.255.255.0]:
Fibre Channel IP Address [220.220.220.2]:
Fibre Channel Subnetmask [255.255.0.0]:
Gateway IP Address [192.168.74.1]:
DHCP [Off]:off
