About Zone-Based Traffic Priority

The zoning feature provides an additional segregation mechanism to prioritize select zones in a fabric
and set up access control between devices. Using this feature, you can configure the quality of service
(QoS) priority as a zone attribute. You can assign the QoS traffic priority attribute to be high, medium,
or low. By default, zones with no specified priority are implicitly assigned a low priority. See the
Versus Zone-Based QoS" section on page 56-6
To use this feature, you need to obtain the ENTERPRISE_PKG license see
Installing Licenses"
page
This feature allows SAN administrators to configure QoS in terms of a familiar data flow identification
paradigm. You can configure this attribute on a zone-wide basis rather than between zone members.
Caution If zone-based QoS is implemented in a switch, you cannot configure the interop mode in that VSAN.

Configuring Zone-Based Traffic Priority

To configure the zone priority, follow these steps:
Command
Step 1
switch# config t
Step 2
switch(config)# zone name QosZone vsan 2
switch(config-zone)#
Step 3
switch(config-zone)# attribute qos priority
high
switch(config-zone)# attribute qos priority
medium
switch(config-zone)# attribute qos priority low
switch(config-zone)# no attribute qos priority
high
Step 4
switch(config-zone)# exit
switch(config)#
Step 5
switch(config)# zoneset name QosZoneset vsan 2
switch(config-zoneset)#
Step 6
switch(config-zoneset)# member QosZone

Configures this zone to assign high priority
QoS traffic to each frame matching this zone.
Configures this zone to assign medium
priority QoS traffic to each frame matching
this zone.
Configures this zone to assign low priority
QoS traffic to each frame matching this zone.
Reverts to using the default low priority for
this zone.
Returns to configuration mode.
Configures a zone set called QosZoneset for
the specified VSAN (vsan 2) and enters zone
set configuration submode.
To activate a zone set, you must first
