Usage Guidelines
•
The string parameter specifies user-defined information to insert into the Circuit ID and Remote ID
fields.
•
When entering a string for user-defined Option-82 information, quotes are required around ambiguous
characters, such as hex characters, spaces, etc, so they are interpreted as text. For example, the string
"Building B Server" requires quotes because of the spaces between the words.
•
The data specified with this command is added to the Circuit ID and Remote ID fields only when
DHCP Option-82 data insertion is enabled for the switch.
•
When DHCP Snooping is enabled at the switch level, Option-82 data insertion is enabled by default.
