Managing Network Connections

Applies To: Microsoft iSCSI Software Target

Microsoft iSCSI Software Target uses the following default network configurations for communication with iSCSI initiators:

  • All network adapters on the storage server are used for storage traffic.

  • Cluster traffic will only bind to the cluster virtual adapter.

  • TCP port 3260 is used for storage services.

You can restrict which network adapters are used.

Communication between the initiator and computers that are running Microsoft iSCSI Software Target can be adversely affected by incorrect IP addresses or extra network ports that cannot be used for iSCSI communication. To avoid this, disable network ports that will not be used in the Microsoft iSCSI Software Target console and ensure that all active network interfaces have appropriate IP addresses. In particular, do not use automatic private IP addressing (169.254.x.x) for communication between the initiator and Microsoft iSCSI Software Target because automatically assigned IP addresses are prevented from binding with Microsoft iSCSI Software Target. IPv4 and IPv6 addresses are supported.

Membership in the local Administrators group, or equivalent, is the minimum required to complete this procedure. Review the details in "Additional considerations" in this topic.

To change the network configuration

  1. In Microsoft iSCSI Software Target, right-click Microsoft iSCSI Software Target, and then click Properties.

  2. On the Network tab, clear the check box for any network adapter that you do not want to be used for storage traffic.

Additional considerations

  • You must be a member of the local Administrators group to perform these tasks.

  • To open iSCSI Software Target, click Start, point to Administrative Tools, and then click Microsoft iSCSI Software Target. (Another way to open iSCSI Software Target is to click Start, click Run, and then type iscsitarget.msc.)
