Priority Level – The priority of the above MAC address. The options are; Low, Med-L – medium low, Med-H –
medium high, and High.
Src/Dst – The state under which the above priority will be active. The options are; Dst. – destionation, Src. –
source, and Either. When Dst. is chosen, packets with the above MAC address as their destination will be given

Mirroring

Traffic from any source port to a target port can be mirrored for real-time analysis. A logic analyzer or an RMON probe can
then be attached to study the traffic crossing the source port in a completely unobtrusive manner. When mirroring port
traffic, note that the target port must be configured in the same VLAN and be operating at the same speed as the source
port. If the target port is operating at a lower speed, the source port will be forced to drop its operating speed to match that
of the target port.
