Note
Throughout this publication and all Catalyst 6000 family documents, the term "COPS" refers to
COPS support as implemented on the Catalyst 6000 family switches.
Port ASICs
Some COPS support features affect all ports controlled by a port ASIC. The following sections use the
term "per-ASIC" to identify features that configure all ports on the same port ASIC:

Understanding QoS Policy
The term QoS policy refers to the QoS values in effect, such as port trust state and which ACLs are
applied to ports and VLANs.
Selecting COPS as the QoS Policy Source
QoS uses locally configured QoS values as the default QoS policy source. To select COPS as the QoS
policy source, perform this task in privileged mode:
Task
Step 1
Select COPS as the QoS policy source.
Step 2
Verify the QoS policy source.

The port ASICs on Gigabit Ethernet switching modules control up to 4 ports each: 1–4, 5–8, 9–12,
and 13–16.
There is a port ASIC on 10-Mbps, 10/100-Mbps, and 100-Mbps Ethernet switching modules that
controls all ports.
On 10-Mbps, 10/100-Mbps, and 100-Mbps Ethernet switching modules, there is another set of port
ASICs that control 12 ports each (1–12, 13–24, 25–36, and 37–48), but COPS cannot configure
them.
Changes to an EtherChannel port apply to all ports in the EtherChannel and to all ports controlled
by the ASIC (or ASICs) that control the EtherChannel ports.
