514 iSCSI Optimization Commands
QoS treatment is accomplished by monitoring traffic to detect packets used
by iSCSI stations to establish iSCSI sessions and connections. Data from
these exchanges is used to create classification rules that assign the traffic
between the stations to a configured traffic class. Packets in the flow are
queued and scheduled for egress on the destination port based on these rules.
In addition, if configured, the packets can be updated with IEEE 802.1p or
IP-DSCP values. This is done by enabling remark. Remarking packets with
priority data provides special QoS treatment as the packets continue through
the network.
