iSCSI Commands
The tasks involved in providing automated QoS preferential treatment of iSCSI flows can be
divided into the following categories:
• Detecting the establishment and termination of iSCSI sessions and connections by snooping
packets used in the iSCSI protocol.
• Maintaining a database of currently active iSCSI sessions and connections to store data about
the par
ticipants. This allows the formulation of classifier rules giving the data packets for the
session the desired QoS treatment.
• Installing and removing classifier rule sets as needed for the iSCSI session traffic.
•
Monitoring activity in the iSCSI sessions to allow for aging out session entries if the session
t
ermination packets are not received.
The means of detecting the establishment and termination of iSCSI sessions is accomplished by
installing classifier rules to trap iSCSI protocol packets to the CPU for examination. This protocol
uses well-known TCP ports for initiators to contact targets with 3260 and 860. Additional port
numbers or “port number/target IP address” can also be configured for monitoring if an
installation uses ports other than the well-known ports. The well-known ports are configured as
part of the default configuration of the component and can be removed if desired by the user.
iscsi enable
The iscsi enable Global Configuration mode command globally enables iSCSI awareness.
