dhcp-snooping information circuit-id format-type
Syntax
dhcp-snooping information circuit-id format-type { ascii | hex }
undo dhcp-snooping information circuit-id format-type
View
Layer 2 Ethernet port view, Layer 2 aggregation interface view
Default Level
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 the dhcp-snooping information circuit-id format-type command to configure the code type for
the non-user-defined circuit ID sub-option.
Use the undo dhcp-snooping information circuit-id format-type command 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.
Note that:
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.
Related commands: display dhcp-snooping information.
Examples
