NETGEAR AV Line M4250 GSM4210PX 8-Port Gigabit PoE+ Compliant Managed AV Switch with SFP (220W) - Manual (Page 484)

A two-rate policy supports two data rates and results in and action for packets
that conform to the policy and an action for packets that violate the policy.
a. Specify the color class:
• Color Blind: This is the default selection. Color classes do not apply.
• Color Aware: Select this radio button to require a color class that is valid
for use with this policy instance. After you select Color Aware from the
Color Mode menu, the Color Conform Class menu displays. From this
menu, select another class (one that you already created, see Configure a
DiffServ class on page 468 or Configure an IPv6 DiffServ class on page 475).
In the context of this policy, we refer to this selected class as the color class.
A valid color class contains a single, non-excluding match criterion, provided
that the criterion does not conflict with the classifier of the policy instance
itself:
b. Specify the traffic rates and bust sizes for packets that conform to the two-rate
policy.
• Committed Rate: Specify the committed rate that is applied to conforming
packets by entering a value in the range from 1 to 4294967295
kilobits-per-second (Kbps). The committed rate is used to guarantee the
allowed bandwidth of conforming traffic.
• Committed Burst Size: Specify the burst size that is applied to conforming
packets by entering a value in the range from 1 to 128 KBytes (KB). The
committed burst size is used to limit the maximum number of bytes in a
burst (a very short instance) of conforming traffic.
• Peak Rate: Specify the peak rate that is applied to conforming packets by
entering a value in the range from 1 to 4294967295 kilobits-per-second
(Kbps). The peak rate is used to limit how much a burst of conforming traffic
can exceed the committed rate.
• Peak Burst Size: Specify the peak burst size that is applied to conforming
packets by entering a value in the range from 1 to 128 KBytes (KB). The
peak burst size is used to limit how much a burst of conforming traffic can
exceed the peak rate.
c. Specify a policy action for packets that conform to the two-rate policy.
• Send: Packets are forwarded unmodified. This is the default confirming
action.
• Drop: Packets are dropped.
• Mark CoS: Packets are marked by DiffServ with the specified CoS value
before being forwarded. This selection requires that the Mark CoS field is
set. You must select a CoS value from 0 to 7 from the menu.
