port on the ingress port, using either percentage of total bandwidth or absolute values for committed
and peak rates in Kbps or Mbps. You also set the priority level for each queue.
To define rate shaping on a port, you assign a minimum and maximum bandwidth or rate plus a
priority value to each queue on the ingress port (see
Table 47 for the number of queues available to each
port on the I/O module). Use the following command to define rate shaping:
configure qosprofile ingress <iqp> [{committed_rate <committed_bps> [k | m]} {maxbw
<maxbw_number>} {minbw <minbw_number>} {peak_rate <peak_bps> [k | m} {priority
[<priority> | <priority_number]}] ports [<port_list> | all]
If you choose to use committed rate and peak rate values, be aware of the interactions between the
values and the command line interface (CLI) management system. You can enter any integer from 0 in
the CLI; however, functionally the switch operates only in multiples of 62.5 Kbps. Also note that the CLI
system does not accept decimals.
Rate shaping is disabled by default on all ports; the system does use existing 802.1p, port, and VLAN
values to assign packets to the ingress queue. The rate shaping function is used to assign specific
priorities by absolute rates or percentages of the bandwidth.
To enable this rate shaping feature, use the configuration command. To disable the rate shaping, use the
following command:
unconfigure qosprofile ingress ports all
To display the parameters for rate shaping (the values for the IQPs), use the following commands:
show qosprofile {ingress | egress} {ports [ all | <port_list>]}
show ports {mgmt | <port_list>} information {detail}
Additionally, you can monitor the performance on the BlackDiamond 10K switch by using the following
command:
show ports <port_list> qosmonitor {ingress | egress} {no-refresh}
NOTE
You must specify
ingress
to view ingress rate shaping performance.
