Configuring Policy Class of Service (CoS)
Parameters
group‐type‐index
transmit‐queue
unit percentage |
kbps | mbps | gbps
rate rate
algorithm tail‐drop
Defaults
•
If a rate is not specified, port defaults will be applied.
•
If not specified, no algorithm will be assigned.
Mode
Switch command, Read‐Write.
Example
This example shows how to configure a Class of Service port resource entry for port group 0.1
assigning 50 percent of the total available inbound bandwidth to transmit queue 7:
Matrix(rw)->set cos port-resource txq 0.1 7 unit percentage 50
clear cos port-resource txq
Use this command to clear one or all Class of Service transmit queue port resource entry.
Syntax
clear cos port-resource txq all | group-type-index resource[unit] [rate]
[algorithm]
Parameters
all | group‐type‐index
resource
unit
rate
algorithm tail‐drop
Defaults
If no options are specified, all associated non‐default settings will be cleared.
8-34 Policy Classification Configuration
Specifies a transmit queue port group/type index for this entry. Valid
entries are in the form of group.type. Group can be 0‐7, with 0
designating the default group, and 1‐7 reserved for user‐defined
groups. Default port type values cannot be changed, and are 0 for the
7GR4270‐12, 7G4270‐12, 7G4270‐09, and 7G4270‐10 DFE modules, and 1
for all other modules.
Specifies a transmit queue to be associated with this entry. Valid values
are 0‐7.
Specifies the unit of measure as percentage of total bandwidth, or
kilobits, megabits, or gigabits per second.
(Optional) Specifies a data rate in units for this transmit queue.
(Optional) Sets the algorithm by which transmit frames are discarded as
discarding frames from the tail of the queue.
Clears all transmit queue port resource entries or a specific entry.
Specifies a resource entry to be cleared.
(Optional) Clears unit of measure settings.
(Optional) Clears rate settings.
(Optional) Clears algorithm settings.
