Configuring QoS on the Switch
Port Operator Parameters
In the IP ACEs, the
operator
parameter can be one of the following:
•
lt
(less than)
•
gt
(greater than)
•
eq
(equal)
•
neq
(not equal)
•
range
(with a pair of port parameters)
See the
“Layer 4 Operations Configuration Guidelines” section on page 15-23
for restrictions that apply
to the QoS ACLs.
Precedence Parameter Options
For the
precedence
parameter keyword options in the IP ACEs, see the
“IP ACE Layer 3 Classification
Criteria” section on page 52-18
.
IP ACEs for TCP Traffic
To create or modify an IP ACE for the TCP traffic, perform this task in privileged mode:
For the
port
parameter keyword options, see the
“IP ACE Layer 4 TCP Classification Criteria” section
on page 52-19
.
The
established
keyword matches the traffic with the ACK or RST bits set.
This example shows how to create an IP ACE for the TCP traffic:
Console> (enable)
set qos acl ip my_IPacl trust-ipprec microflow my-micro aggregate my-agg
tcp any any
my_IPacl editbuffer modified. Use ‘commit’ command to apply changes.

Step 1
Create or modify an IP ACE for the TCP traffic.
