UDP
Version
Shows Version in the IPv6 header.
Traffic class
Traffic class is similar to IPv4's DSCP/TOS and is used for the class and
priority. This is defined in RFC 2474.
Flow label
The Flow label indicates that the datagram belongs to a specific sequence
of traffic between a source and destination. The default value is 0.
Payload length
Shows Payload length in the IPv6 header. This value is calculated
automatically.
Next header
The next header indicates the upper/next layer protocol encapsulated in the
IP datagram. Typical values in hex are: 1 = ICMP, 6 = TCP etc.
Hop limit
The hop limit defines the number of 'hops' a datagram can do before it no
longer is forwarded.
Src IP/Dst IP
Source IP address and Destination IP address can be entered using the
format xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx (32 Hex values).
Touching the UDP layer button displays the parameters available for the
User Datagram Protocol layer.
