Usage Guidelines

The Option55 field in DHCP Request messages is used to set the request option list. DHCP clients use this option to specify network configuration parameters that need to be obtained from the DHCP server. You can run the dhcp client request option-list exclude command to configure a list of default options that are excluded from the Option55 field based on network requirements.

For option meanings, see DHCP Options in Configuration- IP Service Configuration Guide - DHCP Configuration.
