Defines a traffic flow by a source IP address. The address can be of a
specific node or a subnet.

filtering on a subnet. A binary “1” indicates the switch should filter on
the corresponding bit of the IP address, while a “0” indicates that it

would have the mask “255.255.255.0”.
Destination IP Address
Destination IP Mask
Defines a traffic flow by its destination IP address. The address can be
of a specific node or a subnet.
You do not need to include a source IP mask if you are filtering on the
IP address of a specific end node. A mask is required, however, when
filtering on a subnet. A binary “1” indicates the switch should filter on
