QoS: SID/DID traffic prioritization
18
Traffic prioritization is not supported on 10 Gbps ISLs.
Traffic prioritization is not supported on mirrored ports.
Traffic prioritization is not supported over LSAN zones. The traffic is always medium priority in
the ingress edge fabric, the backbone fabric, and the egress edge fabric.
Traffic prioritization is not supported on a CryptoTarget container (redirection zone). See the
Fabric OS Encryption Administrator’s Guide
for information about redirection zones.
Traffic prioritization is not supported in McDATA Fabric Mode (interopmode 2) or Open Fabric
Mode (interopmode 3).
You must be running Fabric OS v6.3.0 or later to create QoS zones using D,I notation.
QoS zones using D,I notation are not supported for QoS over FCR.
QoS zones using D,I notation should not be used for loop or NPIV ports.
If QoS is enabled, an additional 16 buffer credits are allocated per port for 8-Gbps ports in LE
mode. See
Chapter 20, “Managing Long Distance Fabrics,”
for information about buffer credit
allocation in extended fabrics.
Trunking considerations:
If some ports in a trunk group have QoS enabled and some ports
have QoS disabled, then two different trunks are formed, one with QoS enabled and one with
QoS disabled.
Setting traffic prioritization
1.
Connect to the switch and log in as admin.
2.
Enter the
zoneCreate
command. The format varies depending on whether you want high or low
priority traffic.
For high priority traffic, use the following syntax:
zonecreate "
QOSH
id_zonename
", "
member
[
;
member
...]
"
For low priority traffic, use the following syntax:
zonecreate "
QOSL
id_zonename
", "
member
[
;
member
...]
"
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.
3.
Enter the
cfgAdd
command to add the QoS zone to the zone configuration, 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, using the following syntax:
portcfgqos --enable
[
slot
/]
port
