Table B-1 Data String Parameters for Option 43
Parameter Description Field Type
<TargetIP> A valid IPv4 address in dotted decimal notation Mandatory
<TargetTCPPort> A decimal number ranging from 1 to 65535 (inclusive).
The default TCP port is 3260. Optional
<LUN> A hexadecimal representation of the LUN of the boot

<HeaderDigest> Either E (the header digest is enabled) or D (the header
digest is disabled). Optional
<DataDigest> Either E (the data digest is enabled) or D (the data
digest is disabled). Optional
<AuthenticationType> D (authentication is disabled), E (one-way CHAP is
