• 802.1p. The eight priority tags that are specified in IEEE 802.1p are p0 to p7. The
QoS setting lets you map each of the eight priority levels to one of seven internal
hardware priority queues. The default value is 802.1p.
• DSCP.
The six most significant bits of the DiffServ field are called the Differentiated
Services Code Point (DSCP) bits.
10. In the Interface Shaping Rate field, specify the maximum egress bandwidth allowed.
This setting is used to shape the outbound transmission rate in increments of 1 percent in
a range of 0–100.
This value is controlled independently of any per-queue maximum
bandwidth configuration. It is effectively a second-level shaping mechanism. The default
value is 0. The value 0 means that the maximum is unlimited.
11. In the Interface Ingress Rate Limit field, specify the maximum ingress bandwidth allowed.
This setting is used to shape the inbound transmission rate in increments of 1 percent in
a range of 0–100.
The interface discards traffic that arrives at a bandwidth in excess of
the specified limit.
12. Click the Apply button.
Your settings are saved.
Configure the CoS queue settings for an interface
You can define what a particular queue does by configuring switch egress queues. You can
control how much bandwidth is used by the queue, the queue depth during times of
congestion, and the scheduling of packet transmission from all queues on a port. Each port
contains its own CoS queue-related configuration.
For information about configuring CoS queue settings globally, see
Configure the global
CoS settings on page 300.
To configure CoS queue settings for an interface:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is of
f-network using an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser
, enter the IP address of the switch.
If you do not know the IP address of the switch, see
Access the switch on-network and
connected to the Internet on page 21 or Access the switch off-network and not
connected to the Internet on page 29.
