Dynamic Host Configuration Protocol (DHCP)
Recommendations
If you are using the DHCP server to obtain an IP address for the UCNA, Emulex
recommends that you set up a reservation. A reservation assigns a specific IP address
based on the MAC address of the UCNA. If you do not reserve an IP Address through
DHCP, then you must set the lease length for the UCNA IP address to unlimited. This
prevents the IP address lease from expiring.
Vendor-Specific Option 43
This section describes the format for the data returned in DHCP vendor-specific option
43. The method and format for specifying the Vendor ID is outside the scope of this
document and is not included here. The UCNA offers this Vendor ID to the DHCP
server to retrieve data in the format described in this section.
Format of Vendor-Specific Option 43
The following describes the format of option 43 and includes guidelines for creating the
data string:
'iscsi:'<TargetIP>':'<TargetTCPPort>':'<LUN>':'<TargetName>':'
<InitiatorName>':'<HeaderDigest>':'<DataDigest>':'
<AuthenticationType>

Strings shown in quotes are part of the syntax and is therefore mandatory

Fields enclosed in angular brackets (including the angular brackets) should be
replaced with their corresponding values. Some of these fields are optional and
may be skipped.

If an optional field is skipped, a colon must be used as a placeholder to indicate
the default value for that field.

When specified, the value of each parameter should be enclosed in double
quotes. See “Examples” on page 723.

All options are case sensitive.
