IdentifierIdentifier
The IdentifierIdentifier is mainly used for uniquely identifying fragments of an IP
datagram. When the Auto incrementAuto increment check box is selected, the Identifier will be
different for each sent frame.
FlagsFlags
Selecting a check box sets its flag bit to "1".
If the MFMF (More Fragments) flag is set: When a packet is fragmented, all
fragments have the MF flag set except the last fragment.
If the DFDF (Don't Fragment) flag is set: When fragmentation is required to route
the packet, then the packet will be dropped.
RESRES (Reserved) must be zero (i.e. not set).
Fragment offsetFragment offset
Shows Fragment Offset value in the IPv4 header.
TTLTTL
TTL (Time To Live) defines the number of 'hops' a datagram can do before it
no longer is forwarded.
ProtocolProtocol
The ProtocolProtocol field defines the upper/next layer protocol encapsulated in the IP
datagram. Typical values in hex are: 1 = ICMP, 6 = TCP etc.
ChecksumChecksum
Shows a checksum.
IP addressIP address
Src IPSrc IP and Dst IPDst IP can be entered using the format: 255.255.255.255.
When Multistream traffic is sent from one port to another, make sure that the source
address on one port is the same as the destination address on the other port for each of
the active streams. This applies both if the two ports are in one instrument and if they are
in two different instruments.
The following addresses cannot be used for RFC 6349 application tests.
All numbers are zero. (i.e, 0.0.0.0)
Multicast address
Selecting the DHCPDHCP check box located next to the Src IPSrc IP field will enable the
Dynamic Host Configuration Protocol function.
Selecting the DNSDNS check box located next to the Dst IPDst IP field changes the field
name to HostnameHostname, allowing you to specify the domain name server.
Touching the SetupSetup button next to the virtual Lamp in the Src IPSrc IP line will open
the DHCP/DNS SetupDHCP/DNS Setup dialog box.
