A QoS zone is a special zone that indicates the priority of the traffic flow between a given host/target pair. The members of a QoS zone are the host/target pairs. QoS zones can contain WWN members (WWNN or WWPN) or Domain, Index (D,I) members. If you use D,I notation in your QoS zones, see "Limitations and restrictions for traffic prioritization" on page 413 for some considerations you should be aware of. A QoS zone has a special name to differentiate it from a regular zone. The format of the QoS zone name is as follows: For high priority: For low priority: QOSHid_xxxxx QOSLid_xxxxx where id is a flow identifier that designates a specific virtual channel for the traffic flow and xxxxx is the user-defined portion of the name. For example, the following are valid QoS zone names: QOSH3_HighPriorityTraffic QOSL1_LowPriorityZone The switch automatically sets the priority for the "host,target" pairs specified in the zones based on the priority level (H or L) in the zone name. The flow id allows you to have control over the VC assignment and control over balancing the flows throughout the fabric. The id is from 1-5 for high priority traffic, which corresponds to VCs 10-14. For low priority traffic, the id is from 1-2, which corresponds to VCs 8 and 9. The id is optional; if it is not specified, the virtual channels are allocated using a round-robin scheme. NOTE If a QoS zone name prefix is specified in an LSAN zone (a zone beginning with prefix "LSAN_"), the QoS tag is ignored. Only the first prefix in a zone name is recognized. For example, a zone with the name "LSAN_QOSH_zone1" is recognized as an LSAN zone and not a QoS zone. See "QoS over FC routers" on page 408 for additional considerations when using QoS to prioritize traffic between device pairs in different edge fabrics. 406 Fabric OS Administrator's Guide 53-1001763-01

QoS zones
You assign high or low priority (QoS level) using a QoS zone. A
QoS zone
is a special zone that
indicates the priority of the traffic flow between a given host/target pair.
The members of a QoS zone are the host/target pairs. QoS zones can contain WWN members
(WWNN or WWPN) or
Domain, Index
(D,I) members. If you use D,I notation in your QoS zones, see
“Limitations and restrictions for traffic prioritization”
on page 413 for some considerations you
should be aware of.
A QoS zone has a special name to differentiate it from a regular zone. The format of the QoS zone
name is as follows:
For high priority:
QOSH
id
_
xxxxx
For low priority:
QOSL
id
_
xxxxx
where
id
is a flow identifier that designates a specific virtual channel for the traffic flow and
xxxxx
is
the user-defined portion of the name. For example, the following are valid QoS zone names:
QOSH3_HighPriorityTraffic
QOSL1_LowPriorityZone
The switch automatically sets the priority for the “host,target” pairs specified in the zones based on
the priority level (H or L) in the zone name.
The flow
id
allows you to have control over the VC assignment and control over balancing the flows
throughout the fabric. The
id
is from 1–5 for high priority traffic, which corresponds to VCs 10–14.
For low priority traffic, the
id
is from 1–2, which corresponds to VCs 8 and 9. The id is optional; if it
is not specified, the virtual channels are allocated using a round-robin scheme.
NOTE
If a QoS zone name prefix is specified in an LSAN zone (a zone beginning with prefix "LSAN_"), the
QoS tag is ignored. Only the first prefix in a zone name is recognized. For example, a zone with the
name "LSAN_QOSH_zone1" is recognized as an LSAN zone and not a QoS zone.
See
“QoS over FC routers”
on page 408 for additional considerations when using QoS to prioritize
traffic between device pairs in different edge fabrics.
