Specifying a QoS for all packets matching a local Filter profile
Following are the Ethernet > Filters parameters used in the example of specifying a QoS for all
packets matching a local Filter profile:
Parameter Specifies
Src Mask
A subnet mask to apply to the Source-Address value before comparing
the result to the source address in a packet. The MAX translates both
the Source-Address-Mask and Source-Address values into binary
format and then uses a logical AND to apply the
Source-Address-Mask to the Source-Address. The mask hides the
portion of the Source-Address that appears behind each binary 0 (zero)
in the mask. A mask of all zeros (the default) masks all bits. If the
Source-Address value is also all zeros, all source addresses in packets
are matched. A mask of all ones (255.255.255.255) masks no bits, so
the full source address for a single host is matched.
Src Adrs An IP address. After applying the Source-Address-Mask to this value,
the MAX compares the result to the source address in a packet.
Dst Mask
A subnet mask to apply to the Dest-Address value before comparing
the result to the destination address in a packet. The MAX translates
both the Dest-Address-Mask and Dest-Address values into binary
format and then uses a logical AND to apply the Dest-Address-Mask
to the Dest-Address. The mask hides the portion of the Dest-Address
value that appears behind each binary 0 (zero) in the mask. A mask of
all zeros (the default) masks all bits. If the Dest-Address value is also
all zeros, all destination addresses in packets are matched. A mask of
all ones (255.255.255.255) masks no bits, so the full destination
address for a single host is matched.
Dst Adrs An IP address. After applying the Dest-Address-Mask to this value,
the MAX compares the result to the destination address in a packet.
Protocol
A TCP/IP protocol number. A value of zero matches all protocols. If
you specify a nonzero number, the MAX compares it to the Protocol
field in packets. For a complete list of protocol numbers, see RFC
1700.
Src Port Cmp How the MAX compares the source port number in a packet to the
value specified in Source-Port. If you set Src Port Cmp to None, the
MAX makes no comparison. You can specify that the filter matches
the packet if the packet’s source port number is Less (less than), Eql
(equal to), Gtr (greater than), or Neq (not equal to) the Source-Port
value.
Src Port # Port number that the MAX compares to the source port in a packet.
TCP and UDP port numbers are typically assigned to services. For a
list of all port numbers, see RFC 1700.
DstPortCmp How the MAX compares the destination port number in a packet to the
value specified in Dest Port. If you set this parameter to None, the
MAX makes no comparison. You can specify that the filter matches
the packet if the packet’s destination port number is Less (less than),
Eql (equal to), Gtr (greater than), or Neq (not equal to) the Dest-Port
value.
