6. Click the LAG link to display all LAG interfaces or click the All link to display both all physical
and all LAG interfaces.
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 traf
fic 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 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 ef
fectively a second-level shaping mechanism. The default
value is 0. The value 0 means that the maximum is unlimited.
10. 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 traf
fic that arrives at a bandwidth in excess of
the specified limit.
