Setting QoS zone-based traffic prioritization
21
The portCfgQos command does not affect QoS prioritization. It only enables or disables the link
to pass QoS priority traffic.
NOTE
QoS is enabled by default on all ports (except long-distance ports). If you use the portCfgQos
command to enable QoS on a specific port, the port is toggled to apply this configuration, even
though the port already has QoS enabled. The port is toggled because the user configuration
changed, even though the actual configuration of the port did not change.
If you later use the portCfgQos command to enable QoS on the port again, the port is not toggled,
because the configuration did not change.
Example
sw0:admin> zonecreate "QOSH1_zone", "10:00:00:00:10:00:00:00;
10:00:00:00:20:00:00:00"
sw0:admin> zonecreate "QOSL2_zone", "10:00:00:00:30:00:00:00;
10:00:00:00:40:00:00:00"
sw0:admin> zoneshow
sw0:admin> cfgadd "cfg1", "QOSH1_zone"
sw0:admin> cfgadd "cfg1", "QOSL2_zone"
sw0:admin> cfgshow
Defined configuration:
cfg: cfg1 zone1; QOSH1_zone; QOSL2_zone
zone: QOSH1_zone
10:00:00:00:10:00:00:00; 10:00:00:00:20:00:00:00
zone: QOSL2_zone
10:00:00:00:30:00:00:00; 10:00:00:00:40:00:00:00
zone: zone1 10:00:00:00:10:00:00:00; 10:00:00:00:20:00:00:00;
10:00:00:00:30:00:00:00; 10:00:00:00:40:00:00:00
Effective configuration:
No Effective configuration: (No Access)
sw0:admin> cfgsave
You are about to save the Defined zoning configuration. This
action will only save the changes on Defined configuration.
Any changes made on the Effective configuration will not
take effect until it is re-enabled. Until the Effective
configuration is re-enabled, merging new switches into the
fabric is not recommended and may cause unpredictable
results with the potential of mismatched Effective Zoning
configurations.

sw0:admin> cfgenable "cfg1"
You are about to enable a new zoning configuration.
This action will replace the old zoning configuration with the
current configuration selected. If the update includes changes
to one or more traffic isolation zones, the update may result in
localized disruption to traffic on ports associated with
the traffic isolation zone changes
Do you want to enable 'cfg1' configuration (yes, y, no, n): [no] y
zone config "cfg1" is in effect
