Setting QoS zone-based traffic prioritization
14
The id range is from 1 through 5 for high-priority traffic, which corresponds to VCs 10 through
14. For low-priority traffic, the id range is from 1 through 2, which corresponds to VCs 8 and 9.
The id is optional; if it is not specified, the virtual channels are allocated by means of a
round-robin scheme.
3. Enter the cfgAdd command to add the QoS zone to the zone configuration, by using the
following syntax:
cfgadd "cfgname", "QOSzonename"
4. Enter the cfgSave command to save the change to the defined configuration.
5. Enter the cfgEnable command for the appropriate zone configuration to make the change
effective.
cfgenable "cfgname"
6. Enter the portCfgQos command to enable QoS on the E_Ports, by using the following syntax:
portcfgqos --enable [slot/]port
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
