Activating Dhcp; Deactivating Dhcp - HP A7533A - Brocade 4Gb SAN Switch Base Administrator's Manual

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 an HP 8/80 Base 48-ports Enabled SAN Switch is "BROCADESWBD64."
The client conforms to the latest IETF Draft Standard RFCs for IPv4, IPv6, and DHCP.

Activating DHCP

Connect the DHCP-enabled switch 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 connect only 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 are static and are not affected by DHCP; see
page 35 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.
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

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.
