Info

Chapter 10 Drag and drop a symbolic address from the Known Address list into the Station 1 or Station 2 fields. Known addresses come from Broadcast Addresses, the Host Table, or the Address Book. Define the address as either a network hardware address (6 bytes in hexadecimal value) or a network IP or IPX address (4 octets). Select to include or exclude packets that match the address specification. Start capture directly from the Define Filter dialog using this button. 226 Sniffer Portable Professional Specify an optional subnet mask in CIDR format. Figure 10-2. Setting Address Filters First, click to name the new filter. Select which direction the traffic flows by setting the Dir option. Using CIDR Bit-Count Netmasks in the Address Tab You can also just type in an address manually. The Address tab lets you enter subnet masks in the Classless Inter-Domain Routing (CIDR) scheme. CIDR uses a standard 32-bit IP address with a short-hand version of the decimal netmask called a bit count. For example, in the CIDR address 192.168.40.250 with a netmask of 255.255.255.0, 24 is the number of bits in the netmask. So the IP address and netmask can be written as 192.168.40.250/24. If you don’t know your CIDR netmask, you can use Figure 10-3 to convert your subnet mask to a CIDR bit count mask.
