550 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.
iSCSI Optimization borrows ACL lists from the global system pool. ACL lists
allocated by iSCSI Optimization reduce the total number of ACLs available
for use by the network operator. Enabling iSCSI Optimization uses one ACL
list to monitor for iSCSI sessions. Each monitored iSCSI session utilizes two
rules from additional ACL lists up to a maximum of two ACL lists. This
means that the maximum number of ACL lists allocated by iSCSI is three.
Commands in this Chapter
This chapter explains the following commands:
iscsi aging time
The iscsi aging time command sets the time out value for iSCSI sessions. To
reset the aging time to the default value, use the no form of this command.
