QoS zone-based traffic prioritization

To preserve existing trunk groups, before you install the Adaptive Networking license, manually
disable QoS on these ports, as described in “Manually disabling QoS on trunked ports” on
page 524.
Manually disabling QoS on trunked ports
NOTE
QoS is disabled by default on long-distance 8-Gbps and 16-Gbps ports. The following procedure does
not apply to these ports.
1. Connect to the switch and log in using an account with admin permissions.
2. Display the ISL information by using the following command:
islshow
3. Identify E_Ports on which QoS should be manually disabled. In the islshow output; these ports
have all of the following characteristics:
• Are 8-Gbps or 16-Gbps ports
• Have trunking enabled
• Have QoS disabled
4. Check whether QoS is enabled on each port identified in step 3, by using the following
command:
portcfgshow
In the output, the value of QOS E_Port is AE if QoS is automatically enabled by default, ON if
QoS is enabled manually, and OFF or "
.." if QoS is disabled.
5. Manually disable QoS on all of the ports identified in step 3 for which QoS is enabled (in the
portcfgshow output, QOS E_Port is AE or ON).
portcfgqos --disable [slot/]port
ATTENTION
This is a disruptive operation.
Example
In this example, the islshow output displays ports involved in three ISLs:
In the portcfgshow output, the value of QOS_E_Port is AE for port 19 and "
.." for port 24. This
means that QoS is enabled by default on port 19 and disabled on port 24.
You need to disable QoS on port 19.

• Port 2 QoS is already enabled on this ISL, so you should not disable QoS on port 2.
• Ports 19 and 24 QoS is disabled on these ISLs. Check the portcfgshow output to determine
whether QoS is disabled on these ports.
