Figure 76 – QoS > Bandwidth Control

From Port / To Port: A consecutive group of ports may be configured starting with the selected port.

Type: This drop-down menu allows you to select between RX (receive), TX (transmit), and Both. This

setting will determine whether the bandwidth ceiling is applied to receiving, transmitting, or both

receiving and transmitting packets.

No Limit: This drop-down menu allows you to specify that the selected port will have no bandwidth limit.

Enabled disables the limit.

Rate (64-1024000): This field allows you to enter the data rate, in Kbits per second, will be the limit for the

selected port. The value is between 64 and 1024000.

Click Apply to set the bandwidth control for the selected ports.

QoS > 802.1p/DSCP Priority Settings

QoS is an implementation of the IEEE 802.1p standard that allows network administrators to reserve

bandwidth for important functions that require a larger bandwidth or that might have a higher priority, such as

VoIP (voice-over Internet Protocol), web browsing applications, file server applications or video conferencing.

Thus with larger bandwidth, less critical traffic is limited, and therefore excessive bandwidth can be saved.

The following figure displays the status of Quality of Service priority levels of each port, higher priority means

the traffic from this port will be first handled by the switch. For packets that are untagged, the switch will

assign the priority depending on your configuration.

Figure 77 – QoS > 802.1p Default Priority

By selecting the DSCP priority, the web pages will changes as seen below:

1 2 ... 45 46 47 48 49 50 51 52 53 54 55 ... 70 71
