undo dhcp-snooping information circuit-id format-type
View
Layer 2 Ethernet port view, Layer 2 aggregate 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
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.
