•
When outbound rate shaping is enabled on a port on an IPv4 device, the port QoS queuing method (
qos mechanism
) will be strict
mode. This applies to IPv4 devices only. On IPv6 devices, the QoS mechanism is whatever method is configured on the port, even
when outbound rate shaping is enabled.
•
You can configure a rate shaper for a port and for the individual priority queues of that port. However, if a port rate shaper is
configured, that value overrides the rate shaper value of a priority queue if the priority queue rate shaper is greater than the rate
shaper for the port.
•
You can configure rate shaping on individual ports of the link aggregation group (LAG). You cannot configure rate shaping on the
LAG itself.
•
You can enable rate shaping on the individual ports for static and dynamic LAG. You cannot enable rate shaping on other types of
LAG (for example, keepalive).
•
We do not support port-based rate shaping for PE ports.
•
You cannot configure rate shaping on devices where the packet-forwarding method is cut-through. On ICX 7750 devices, the
default packet-forwarding method is cut-through so you must first configure the
store-and-forward
command to change the
method to store-and-forward. On ICX 7450 devices, store-and-forward is the default method.
NOTE
You must save the configuration and reload for the change to take effect. Refer to the description of the
store-and-
forward
command for more information.
•
When configuring rate shaping on dynamic LAG for ICX 7750 devices, you should configure the queues where the Link
Aggregation Control Protocol (LACP) packets are not forwarded. If you configure rate shaping on dynamic LAG ports (either on the
port or on the queue), LACP packets can be dropped and cause a dynamic LAG failure
For more information on LAG configuration, refer to the
Ruckus FastIron Layer 3 Routing Configuration Guide
.
The configured rate shaping values are rounded up to the nearest multiples of minimum values supported on the platform. The following
table shows the minimum and maximum values for output rate shaping on various devices. Values are in kilobits per second (Kbps) for all
the platforms.
