configure ports rate-limit map cos high
configure ports <port_list> rate-limit map cos high <cos_value>
Description
Maps the CoS value to the high queue at ingress. In strict priority rate limiting or HQoS, the system has
three queues: high, medium, and low. Using the ACLs to classify traffic, the system assigns packets to
one of these queues based on the CoS value, with the other CoS values automatically cascading the
packets to the other queues.
Syntax Description
Default
The default CoS value to queue mapping on ingressing packets is as follows:
● High—7
● Medium—6
● Low—5, 4, 3, 2, 1, 0, and untagged packets
Usage Guidelines
With HQoS, you can configure which CoS value directs the packet to the high queue, and the remaining
CoS values are automatically queued. You can configure this value from 7 to 2.
If you attempt to enter a value other than 2 to 7, the system returns the following error message:
Error: highPriCosVal value can range between 2 and 7
NOTE
All packets with a CoS value higher than that configured for the high queue automatically go to the low queue. (If
you configure 2 as the CoS value for the high queue, packets with a CoS value of 3 to 7 all go to the low queue.)
For example, if you configure 5 as the CoS value for the high queue, the queues contain packets with
the following CoS values:
● High contains 5
● Medium contains 4
● Low contains 3, 2, 1, 0, 7, 6, and those with no CoS value
To display the configured CoS value mapped to the high queue for the specified ports for strict priority
rate limiting, issue the
show port information detail command (the setting displays on the High
Priority COS line).
ports Specifies the port or ports you are mapping the high queue CoS value for.
cos_value Specifies the Cos value you want for the high queue for the specified ports. You can
configure this value from 7 to 2.
