Configuring Rate Limitation
IPmux-24 supports data rate limitation at the egress and ingress of the network
and user ports. IPmux-24 limits the data rate proper, without taking into account
Ethernet frame intergaps.
Configuring Ingress Rate Limitation
Via ingress rate limitation the user controls the rate of traffic received at the
network and user interfaces. The traffic that exceeds the selected rate limitation
value for an IPmux-24 port is dropped. In addition to that IPmux-24 defines
maximum packet burst for each rate limitation value. This enables service
providers to compensate their subscribers for underused bandwidth by allowing
temporary traffic bursts. Also, the rate limitation can be applied to all packets or
to their certain types (broadcast, multicast, etc).
The 100–666 Mbps data rates are not supported by IPmux-24 with Fast Ethernet
interfaces.
³ To configure the ingress rate limitation:
1. From the Rate Limitation menu (Configuration > QoS > Rate Limitation),
select Ingress.
The Ingress menu is displayed (
Figure
4-38
).
2. From the Ingress menu, type f to select the network or user port to which
you intend to apply rate and burst limitation.
3. Select Rate Limitation and define the maximum ingress data rate allowed on
the port (see
Table
4-13
).
4. Select Burst Size and define the maximum allowed size of the packet buffer (in
kilobytes) to be used by the port when traffic bursts occur. See
Table
4-13
for
the allowed burst values depending on configured port rate limitation. Traffic
