Ruckus Wireless Ruckus ICX 7150 Series, Configuration Manual

Page: 18 / 65

NOTE
On a Ruckus ICX 7150, frames may be dropped before they are properly scheduled due to a shallow queue depth. Under this
condition, configure the egress buffer profile to support WRR or Mixed mode and increase the port-share level of the profile.
If you create a profile specifying only the weights without specifying the mechanism, the default mechanism is used. The default mechanism
for stacking systems is
Mixed
and
WRR
for standalone systems.
If you change the profile mechanism, the weights also get changed according to the mechanism. The weights can be modified according to
the following requirements:
• If the mechanism is changed to
WRR
, the default system weights get assigned.
• If the mechanism is changed to
Mixed
, the default mix weights get assigned.
• If the mechanism is changed to
Strict
, the weights are ignored and remain untouched.
Scheduler profile modifications take effect dynamically on an active profile.
The following tables show the default values for the scheduling type for stacking and standalone ICX devices.

QoS priorities-to-traffic assignment
By default, all traffic is in the best-effort queue (qosp0) and is honored on tagged ports on all FastIron switches.
You can assign traffic to a higher queue based on the following:
• Incoming port (sometimes called the
ingress port
)
• Static MAC entry
