DESCRIPTION
Only frames matching MAC details configured in this
section will be allowed to pass through (Source/ Destination
MAC Address, Source/ Destination MAC Mask), with the
possibility to select the packet type (IPv4, IPv6, ARP or 'any').
When IPv4/ IPv6 is selected, the board will filter for any
packet of those types. In order to filter for the IPv4/ IPv6
details, the user needs to fill in the related fields (Source/
Destination IP Address, Source/ Destination IP Mask). The
Protocol Type setting is configurable only for IPv4/ IPv6,
allowing the user to restrict the traffic to a specific type of
L4 header (TCP, UDP, ICMP, IGMP). ' A ny' allows filtering a
custom EtherType or setting no filter for L3 headers.
When UDP/ TCP is selected in Protocol Type, only packets
matching the Transport layer details configured in this
section will be allowed to pass through. This can be done
by clicking on the UDP/ TCP group configuration button,
creating a group, naming it and deciding how the port group
will appear, by listing the exact ports followed by comma
or by selecting a range of allowed ports. After creating the
group, in order to be activated, the desired filter needs to be
selected by typing the respective group name in the Source/
Destination Ports Groups subsection. One or more groups
are allowed.
Can be used for filtering as outer/ inner VLAN. This can be
done by clicking on VLAN ID group configuration button,
creating a group, naming it and deciding how the port group
will appear, by listing the exact ports followed by comma
or by selecting a range of ports. After creating the group, in
order to be activated, the desired filter needs to be selected
by typing the respective group name in the Outer/ Inner
VLAN ID subsection. The selections cannot overlap.
