2: System level

Parameters

ascii: Specifies the code type for the circuit ID sub-option as ascii.

hex: Specifies the code type for the circuit ID sub-option as hex.

Description

Use dhcp-snooping information circuit-id format-type to configure the code type for the non-user-defined circuit ID sub-option.

Use undo dhcp-snooping information circuit-id format-type to restore the default.

By default, the code type for the circuit ID sub-option depends on the padding format of Option 82. Each field has its own code type.

This command applies to configuring the non-user-defined circuit ID sub-option only. After you configure the padding content for the circuit ID sub-option using the dhcp-snooping information circuit-id string command, ASCII is adopted as the code type. The private padding format supports only the hex code type.

Related commands: display dhcp-snooping information and dhcp-snooping information format.
