QoS: SID/DID traffic prioritization

3. Identify E_Ports on which QoS should be manually disabled. In the islshow output, these ports
have all of the following characteristics:
• 8 Gbps ports
• Trunking is enabled
• QoS is disabled
4. Check whether QoS is enabled on each port identified in step 3 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
This is a nondisruptive operation.
Example
In this example, the islshow output displays ports involved in four 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 enabled on this ISL, so you should not disable QoS on port 2.
• Port 8 QoS is disabled on this ISL; however, this is a 4 Gbps port, so you do not
need to disable QoS on port 8.
• Ports 19 and 24 QoS is disabled on these ISLs. Check the portcfgshow output to
determine whether QoS is disabled on these ports.
