to restore the default.
By default, the padding format for Option 82 is
normal
.
When you use the
undo dhcp-snooping information format
command:
•
If the
verbose
node-identifier
argument is not specified, the padding format will be restored to
normal
.
•
If the
verbose
node-identifier
argument is specified, the padding format will be restored to
verbose
with MAC address as the node identifier.
