6. Select whether to display physical interfaces, LAGs, or both by clicking one of the following
links above the table heading:
• 1 (the unit ID of the switch). Only physical interfaces are displayed. This is the default
setting.
• LAG. Only LAGs are displayed.
• All. Both physical interfaces and LAGs are displayed.
7. Select one or more interfaces by taking one of the following actions:
• To configure a single interface, select the check box associated with the port, or type
the port number in the Go To Interface field and click the Go button.
• To configure multiple interfaces with the same settings, select the check box
associated with each interface.
• To configure all interfaces with the same settings, select the check box in the heading
row.
8. From the Interface Trust Mode menu, select one of the following trust mode options for
ingress traffic on the selected interfaces:
• Untrusted. Do not trust any CoS packet marking at ingress.
• 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.
9. In the Interface Shaping Rate field, specify the maximum bandwidth allowed.
This is typically used to shape the outbound transmission rate in increments of 64 kbps in
the range 16 to 16384 kbps.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.
The expected shaping at egress interface is calculated as follows:
frameSize × shaping/(frameSize + IFG), where IFG (Inter frame gap) is 20 bytes,
frameSize is configured frame size, and shaping is configured traffic shaping.
For example, when 64 bytes frame size and 64 kbps shaping are configured, expected
shaping is approximately 48 kbps.
