What Information Does the Switch Track in iSCSI Traffic Flows?

Packets are examined to find the following data, which is used in tracking the

session and creating the classifier entries that enable QoS treatment:

Initiator's IP Address

Target's IP Address

ISID (Initiator defined session identifier)

Initiator's IQN (iSCSI Qualified Name)

Target's IQN

Initiator's TCP Port

Target's TCP Port

If no iSCSI traffic is detected for a session for a configurable aging period, the

session data is cleared.

The iSCSI feature includes auto-provisioning support with the ability to

detect Dell EqualLogic SAN storage arrays on the network and automatically

reconfigure the switch to enhance storage traffic flows.

The PowerConnect M6220/M6348/M8024/M8024-k switch uses LLDP , a

vendor-neutral protocol, to discover Dell EqualLogic devices on the network.

LLDP is enabled by default. For more information about LLDP, see

"Discovering Network Devices" on page 663.

When the switch detects a Dell EqualLogic array, the following actions occur:

Spanning-Tree portfast is enabled on the interface identified by LLDP.

Unicast storm control is disabled on the interface identified by LLDP.
