Setting Up CBQ
Use the set port queue service cbq command to set a port, port range, or
module to use class-based queuing (CBQ) queue servicing. The syntax of
the command is:
(configure)# set port queue service {{<mod-num> | <mod-swport-
range>} [..., {<mod-num> | <mod-swport-range>}] | all-ports} cbq queue
<queue> bit-rate <rate>
For information about how the CBQ queue-servicing algorithm works, see
“CBQ” earlier in this chapter.
Table 25-22. Keywords, Arguments, and Options
Keyword, Argument or
Option Definition
<mod-num> The slot number of a module. If you specify
<mod-num>, all ports on the module are set
to use CBQ.
<mod-swport-range> The slot number of a module, and, either a
port number, or a range of port numbers
having the format Px-Py. For example:
• To specify port 1 on the module in slot
3, enter 3/1.
• To specify ports 1 through 5 on the
module in slot 3, enter 3/1-5.
If you specify <mod-swport-range>, the port
or range of ports that you specify is set use
CBQ.
all-ports All ports in the chassis. If you specify all-
ports, all ports on all modules in the chassis
are set to use CBQ.
<queue> The queue number, which can range from 0 to
7.
<rate> The maximum bits per second that you want
to assign to the queue.
If the switch is operating in Fabric mode 1,
the rate can range from 220 Kbps to 1.5 Gbps.
If the switch is operating in Fabric mode 2,
the rate can range from 270 Kbps to 1.5 Gbps
Entering a rate of 0 disables the queue.
