Parameters
vlan
vlan-id
: Specifies a VLAN ID, in the range of 1 to 4094.
circuit-id
: Padding content for the user-defined circuit ID sub-option, a case-sensitive string of 3 to 63
characters.
Description
Use the
dhcp-snooping information circuit-id string
command to configure the padding content for
the user-defined circuit ID sub-option.
Use the
undo dhcp-snooping information circuit-id string
command to restore the default.
By default, the padding content for the circuit ID sub-option depends on the padding format of Option
82.
Note that:
z
After you configure the padding content for the circuit ID sub-option using this command, ASCII is
adopted as the code type.
z
If a VLAN is specified, the configured circuit ID sub-option only takes effect within the VLAN; if no
VLAN is specified, the configured circuit ID sub-option takes effect in all VLANs. The former case
has a higher priority; that is, the circuit ID sub-option specified for a VLAN will be padded for
packets within the VLAN.
