8. Inner Tag Priority Set the frame priority level from 0 (lowest) to 7 (highest) to prioritize different
classes of traffic.
9. IP Header DSCP This value will be put in the IP Header TOS field. Enter a value from 0 to 63.
10. IP Header ECN This value will be put in the IP Header TOS field. Enter a value from 0 to 4.
11. IP Header DF Bit This value will be put in the IP Header DF bit. Enter a value of 0 or 1.
12. IP Header TTL This value will be put in the IP Header TTL field. Enter a value from 0 to 255.
13. IP Header Protocol Specify the IP data packet format. Press the Space bar to select between the
options:
• UDP: use UDP/IP protocol format.
• TCP: use TCP/IP protocol format.
14. UDP/TCP SRC Port This value will be put in the UDP/TCP header Source Port field. Enter a
value from 0 to 65535.
15. UDP/TCP DST Port This value will be put in the UDP/TCP header Destination Port field. Enter a
value from 0 to 65535
16. TCP Sequence Number This value will be put in the TCP header Sequence Number field. It is
not used for the UDP packet. Enter a value from 0 to 4294967295.
17. TCP Ack Number This value will be put in the TCP header Acknowledgement Number field. It is
not used for the UDP packet. Ack Num: Enter a value from 0 to 4294967295.
18. TCP Flags (aka Control bits) contains 8 1-bit flags
• CWR (1 bit) Congestion Window Reduced (CWR) flag is set by the sending host
to indicate that it received a TCP segment with the ECE flag set and had
responded in congestion control mechanism (added to header by RFC 3168).
• ECE (1 bit) ECN-Echo indicates that the TCP peer is ECN capable if the SYN flag
is set. If the SYN flag is clear, a packet with a Congestion Experienced flag in the
IP header set was received during normal transmission and added to header by
RFC 3168.
• URG (1 bit) Indicates that the Urgent pointer field is significant
•
ACK (1 bit)
indicates that the Acknowledgment field is significant. All packets after
the initial SYN packet sent by the client should have this flag set.
• PSH (1 bit) Push function
• RST (1 bit) Reset the connection
•
SYN (1 bit)
Synchronize sequence numbers. Only the first packet sent from each
end should have this flag set. Some other flags change meaning based on this
flag. Some are only valid for when this flag is set, and others when it is clear.
• FIN (1 bit) No more data from sender.
This value will be put in the TCP header Control Bits field. It is not used for the UDP
packet. Enter a value from 0 to 255.
19. TCP Window Size This value will be put in the TCP header Window Size field. It is not used for
the UDP packet. Enter a value from 0 to 65535.
20. TCP Urgent Pointer If the URG flag is set, then this 16-bit field is an offset from the sequence
number indicating the last urgent data byte.
