QoS zones

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 ports 2 and 19 and ON for port 8. This
means that QoS is enabled by default on ports 2 and 19 and enabled manually on port 8.
Port 19 is an 8 Gbps port, so you do not need to enable QoS unless this is also a long-distance port.
The portcfgshow output indicates that port 19 is a long-distance port (Long Distance is ON).
You need to manually enable QoS on ports 2 and 19.

•
Ports 2 and 8 QoS is enabled on these ISLs. Check the portcfgshow output to determine
whether QoS is disabled on these ports.
•
Port 19 QoS is enabled on this ISL. Because this is an 8 Gbps port, check the
portcfgshow output to determine whether this is a long distance port and
whether QoS is disabled on this port.
•
Port 24 QoS is disabled on this ISL, so you should not enable QoS on port 24.
