5: Monitoring & Filtering
Traffic filters
To develop specific access policies and to make traffic monitoring more efficient and effective, custom (layer 2 or IPv4)
filters can be applied to the traffic before it is presented on the monitor ports. This reduces overhead and enables access
policies and monitoring to be targeted at specific types of traffic only.
By default, commonly used filters are defined for both layer 2 and IPv4.
Viewing L2 filters
To view a list of active L2 traffic filters, open the Traffic > L2 Filters page. By default, commonly used filters are defined.
The following information is presented for each filter:
•
Filter name: Unique name assign to the filter.
•
MAC destination: Indicates the destination MAC address assigned to the filter. The filter will only process frames
being sent to this address. The address is specified as six pairs of hexadecimal digits separated by colons
(xx:xx:xx:xx:xx:xx).
•
MAC source: Indicates the source MAC address assigned to the filter. The filter will only process frames received
from this address. The address is specified as six pairs of hexadecimal digits separated by colons
(xx:xx:xx:xx:xx:xx).
•
Ethertype: Identifies the Ethernet frame type that this filter will process. Other frame types are ignored.
•
VLAN1: Indicates the VLAN ID assigned to the filter. The filter will only process frames tagged with this VLAN ID.
•
VLAN 2: Indicates the second VLAN ID assigned to the filter. Used to process VLAN in VLAN traffic.
