Traffic Scan
Monitored Frames Table
Statistics are gathered for each different traffic flow matching the scan
criteria. Each different monitored traffic flow creates a separate entry in the
scan table. When the limit is reached, new traffic flows are not considered
in the table but the existing traffic flows are still monitored.
The level of VLAN (untagged, E-VLAN, S-VLAN, C-VLAN), and values of
VLAN ID, Priority, and TPID are used to identify a traffic flow. Any difference
in one of these values will create a separated entry in the table. PBB-TE
frames are ignored.
Note: Scan statistics are cleared when restarting the scan.
