Capture Filters, Logging, and Subnets:Module Objectives
Capture Filters, Logging, and Subnets:Module Objectives
Create capture filters that control whether frames are stored in the Advisor capture buffer or not.
Set up to log data for baselining and benchmarking.
Implement user defined subnet entries to tell the Advisor how to group addresses on your network.

Subnet Mask InfoSubnet Mask Info
10.6.72.102 is an IP address, and 255.255.0.0 is a subnet mask.
IP uses numbers (addresses) to identify networksand to identify individual components of networkscalled hosts (e.g., a workstation or a router).
10.6 NetworkHost: 72.102
Host: 72.103
Host: 72.104
These addresses are divided into 4 octets giving a total of 32 bits to work with.
The 1’s in a subnet mask mark the network ID and the 0’s mark the hosts.
10.6.72.102 = 00001010 . 000000110 . 01001000 . 01100110
255.255.0.0 = 11111111 . 11111111 . 00000000 . 00000000
Given an IP address and a subnet mask, the network number and host number can be determined. This network ID is 10.6, this particular host is 72.102.

Troubleshooting Using SubnetsTroubleshooting Using Subnets
If no User Defined Subnets were entered, this address would be 15.0.0.0 (Class A)and you would not see that 15.70.64.0 and15.6.72.0 were separate subnets.
These nodes are connected to thesubnet 15.6.72.0
2,890 frames: 15.70.64.0 to 15.70.64.0
2,044 frames: 15.70.64.0 to 15.6.72.0

You can create capture filters that control whether frames are stored in the Advisor capture buffer or not.
You can log data for baselining and benchmarking.
User defined subnet entries tell the Advisor how to group addresses on your network.
