3.1.5 QoS Statistics
The section describes that switch could display the QoS detailed Queuing counters for a specific switch port. for the
different queues for all switch ports.
Web Interface
To display the Queuing Counters in the web interface:
1. Click Configuration, Port, then QoS Statistics
2. If you want to auto-refresh the information then you need to activate “Auto-refresh”.
3. Click “ Refresh“ to refresh the Queuing Counters or click "Clear" to clear all information.
Figure 3-1.5: The Queuing Counters Overview
Parameter description:
Port:
The logical port for the settings contained in the same row.
Qn:
Qn is the Queue number, QoS queues per port. Q0 is the lowest priority queue.
Rx/Tx:
The number of received and transmitted packets per queue.
Auto-refresh:
To activate the auto-refresh to refresh the Queuing Counters automatically.
Refresh
Refresh the Queuing Counters manually.
Clear
Clear the Queuing Counters manually.
3.1.6 EEE
EEE is a power saving option that reduces the power usage when there is very low traffic utilization (or no traffic).
EEE works by powering down circuits when there is no traffic. When a port gets data to be transmitted all circuits are
powered up. The time it takes to power up the circuits is named wakeup time. The default wakeup time is 17 us for 1Gbit
links and 30 us for other link speeds. EEE devices must agree upon the value of the wakeup time in order to make sure
that both the receiving and transmitting device has all circuits powered up when traffic is transmitted. The devices can
exchange information about the devices wakeup time using the LLDP protocol.
For maximizing the power saving, the circuit isn't started at once transmit data are ready for a port, but is instead queued
until 3000 bytes of data are ready to be transmitted. For not introducing a large delay in case that data less than 3000
bytes shall be transmitted, data are always transmitted after 48 us, giving a maximum latency of 48 us + the wakeup
time.
