Address range size Configures the number of IPv4 addresses within an address
range.
This control is valid only if Destination type is set to Range. In
this case, the IP datagrams transmitted in the current stream
will contain as many destination addresses as previously
configured in this field. The destination IP address is
increased by one unit for each transmitted frame starting with
the value configured in Destination IPv4 address. If there are
no more addresses left in the range, transmission returns to
the initial address and starts the process from the beginning.
Transmission of destination IPv4 address ranges is compati-
ble with transmission of destination MAC address ranges but
the address number of the MAC address range is always
fixed to the same number that the IP range. It is not possible
to transmit a destination MAC address range with a single
IPv4 address.
Destination host
name
Domain name to be used as a destination if Destination type
is set to Domain name.
Unlike IP addresses, domain names are easy-to-remember
alphanumeric strings but they have to be translated to IP
addresses before any packet can be sent to the destination.
The translation process requires the intervention of at least
one DNS server. The DNS server IP address has to be con-
figured in the local port profile either statically or by means
DHCP.
DSCP Differentiated Services Code Point. It is 6-bit class of service
(CoS) field defined to set packet groups with different priori-
ties or to provide specific treatments to special packets within
a network or an administrative domain.
Any value from 0 to 63 is allowed for this field. Specific
actions to be carried out on frames with different DSCPs
depend on the network and the service provider.
TTL Initial Time To Live value configured in the packets transmit-
ted in the current stream.
The TTL is decreased by one unit each time it lefts a network
node. If the value reaches zero, then the packet is discarded.
The TTL is then a measure of the number of nodes the
packet is allowed to transverse before reaching its destina-
tion.
