feature.

Zone Database Information

If required, you can clear configured information stored in the zone server database.
Note Clearing a zone set only erases the full zone database, not the active zone database.

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 47-6
To use this feature, you need to obtain the ENTERPRISE_PKG license (see
Installing
section on 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.
To configure 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

switch(config-zone)# attribute qos priority

switch(config-zone)# attribute qos priority low
switch(config-zone)# no attribute qos priority

Purpose
Enters configuration mode.
Configures an alias name (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.
