layer-3 refined QoS features to ensure classification and sorting of network traffic and to avoid congestion in the best way. Before a packet enters the shared buffer, the Catalyst 3550 smart Ethernet switch can classify, reclassify, and process the incoming packet according to the policy (determine whether the packet flow is from the intended user or not, and take action on the package. Packet Classification allows network devices to differentiate t

Restart the switch (because 2950 does not have a power switch, you can directly unplug the power cord and connect it back.) 3. Press the MODE key at the start to enter the switch MODE. Note: the action here is faster, otherwise it will be useless to enter the normal mode. 4. After t
