# View IP interfaces details

Unisphere provides monitoring and management for Internet Small Computer Systems Interface (iSCSI) directors, iSCSI ports, iSCSI endpoints, IP interfaces, and IP routes.

## Steps

1. Select a storage system.
2. Select System > iSCSI to open the iSCSI dashboard.
3. Click IP Interface to open the IP Interface list view and select a specific director to filter the list.
4. Select a row from the list and click to open the IP Interfaces details view.

   The following properties display, depending on the operating environment:

   Dir:Port | The combination of the physical director and the associated port of the IP interface.
   Network ID | The network identity of the IP interface that provides isolated IP routes. This value can be modified.
   IP Address | The destination IPv4 or IPv6 address of the IP interface. This value can be modified.
   Prefix | IPv4 or IPv6 prefix length. This value can be modified. You specify an IPv4 prefix length value in the range of 1 through 30. You specify an IPv6 prefix length value in the range of 1 through 128.
   VLAN ID | The VLAN tag number of the IP interface.
   Maximum Transmission Unit | The maximum transit size of the Ethernet packet for this IP interface. This value can be modified.
   Dir:Virtual Port | The combination of the physical director and the assigned virtual port or iSCSI endpoint alias of the IP interface.
   iSCSI Endpoint | The iSCSI endpoint IQN for the attached endpoint.
   Volumes | The total number of volumes mapped to the iSCSI endpoint attached to the IP interface.
   Volume Set Addressing | Enables the volume set addressing mode. When using volume set addressing, you must specify a four-digit address in the following range: (0)000-(0)007, (0)010-(0)017, and so on, to a maximum of (0)FF0-(0)FF7. The first digit must always be set to 0 (the storage systems do not currently support the upper range of volume set).
   Environ Set | Enables the environmental error reporting by the storage system to the host on the specific port.
   Avoid Reset Broadcast | Enables a SCSI bus reset to only occur to the port that received the reset (not broadcast to all channels).
   Disable Q Reset on UA | When enabled, a Unit Attention (UA) that is propagated from another director does not flush the queue for this volume on this director. Used for hosts that do not expect the queue to be flushed on a 0629 sense (only on a hard reset).
   Soft Reset | Supports SCSI soft reset on a storage system port when enabled for a Bull GCOS-7 host.
   SCSI 3 | Alters the inquiry data (when returned by any volume on the port) to report that the storage system supports the SCSI-3 protocol. When disabled, the SCSI-2 protocol is supported.
   SCSI Support1(OS2007) | Provides a stricter compliance with SCSI standards for managing volume identifiers, multiport endpoints, unit attention reports, and the absence of a volume at LUN 0.
   SPC2 Protocol Version | SPC2 Protocol version
   Open VMS | This flag should be enabled (default) in a Windows 2003 environment running Microsoft HCT test version 12.1. When setting this flag, the port must be offline.
   ISID Protected | Enables an Open VMS fibre connection.

   iSCSI Endpoints | The list view of iSCSI endpoints listing the single attached iSCSI endpoint.
   iSCSI Ports | The list view of iSCSI ports listing the single attached iSCSI port.
   Mapped Volumes | The list view of volumes that are mapped to iSCSI endpoints associated with the director.
