Remarks
N/A
By default, handling of
Option 82 is disabled.
By default, the handling
strategy is replace.
If the handling strategy is
replace, configure a
padding mode and a
padding format for Option
82. If the handling strategy
is keep or drop, you do not
need to configure a padding
mode or padding format for
Option 82.
By default, the padding
mode for Circuit ID
sub-option is normal, and
the padding format is hex.
The device name
(sysname) must not include
spaces if it is configured as
the padding content for
sub-option 1. Otherwise, the
DHCP relay agent will fail to
add or replace Option 82.
By default, the padding
mode for the Remote ID
sub-option is normal, and
the padding format is hex.
Remarks
