IP Fragment – Indicates whether or not fragmented packets
are accepted. (Options: Any, Yes, No; Default: Any)
Datagrams may be fragmented to ensure they can pass through
a network device which uses a maximum transfer unit smaller

of 0-63, BE, CS1-CS7, EF or AF11-AF43, or Range;
Default: Any)
■
IPv6 – IPv6 frame type includes the same settings as those used

put in the queue corresponding to the specified QoS class, or placed in
a queue based on basic classification rules. (Options: 0-7, Default (use
basic classification); Default setting: 0)
◆
DPL – The drop precedence level will be set to the specified value or
left unchanged. (Options: 0-1, Default; Default setting: Default)
