5. Traffic Meter and Shaping
The Ethernet Routing Switch 5500 supports both policing/metering of ingres s traffic in addition to
egress port shaping. The meter and shape range is as shown in table 6 be low. Please note that
all QoS levels are respected and honoured on a shaped interfac e.
Table 6: Meter and Shaping Range and Granularity
Product Meter/Shaper Range Granularity Bucket Size
ERS5510 1 Mbps to 1023 Mbps 1 Mbps 8 buckets
ERS5520 1 Mbps to 1023 Mbps 1 Mbps 8 buckets
ERS5530
(10M/100M,1G) 64 Kbps to 1023 Mbps 64 Kbps 8 buckets
ERS5530 (10G) 1 Mbps to 1023 Gbps 1 Mbps 12 buckets
When configuring traffic metering or shaping, a committed rate, a max imum burst size and burst
duration is entered. The maximum burst rate and burst duration is used along with the committed
rate to setup a fixed token bucket where each token represents 1 byte. Up to eight f ixed bucket
sizes are supported for all 10/100 Mbps and GigE ports. Up to twelve fixed buc ket sizes are
supported on the ERS5530 only via the 10 GigE interface. The token buck et allows a committed
burst to occur up to the token bucket size.
For traffic metering, an in profile and an out of profile action is c onfigured and is expressed as an
id. You can use one of the default actions or create a new action prior to configuring a meter. To
view the action id’s, please use the command shown below. For exam ple, if you wish to remark
the in profile traffic with a QoS level of Bronze and drop traff ic for out of profile traffic, select id 3
and 1 respectively. Please note that you must associate the classifier to identify IP traffic since
the DSCP value is being remarked.
