# View IP interfaces

Unisphere provides monitoring and management for NVMe/TCP directors, NVMe/TCP ports, NVMe/TCP endpoints, IP interfaces, and IP routes.

## Steps

1. Select a storage system running PowerMaxOS 10 (6079).
2. Select System > iSCSI+NVMe and click the NVME tab to open the NVMe dashboard.
3. Click IP Interfaces.
   The following properties display, depending on the operating environment:

   Dir:Port | The combination of the physical director and associated port of the IP interface.
   Network ID | The network identity of the IP interface that provides isolated IP routes.
   IP Address | The destination IPv4 or IPv6 address of the IP interface.
   Prefix | The network mask IPv4 or IPv6 prefix value of the IP interface.
   VLAN ID | The VLAN tag number of the IP interface.
   Dir:Virtual Port | The combination of the physical director and assigned virtual port or NVMe/TCP endpoint alias of the IP interface.
   Volumes | The total number of volumes mapped to the NVMe/TCP endpoint attached to the IP interface.
   Maximum Transmission Unit | The maximum transit size of the Ethernet packet for this IP interface.

   To see more information about a NVMe/TCP IP interface, select it and click .

   The following parameters are displayed:

   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 property can also be modified.
   IP Address | The destination IPv4 or IPv6 address of the IP interface. This property can also be modified.
   Prefix | IPv4 or IPv6 prefix length. This property can also 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 property can also be modified.
   Dir:Virtual Port | The combination of the physical director and the assigned virtual port or NVMe/TCP endpoint alias of the IP interface.
   NVMe/TCP endpoint | The NVMe/TCP endpoint ID.
   Volumes | The total number of volumes mapped to the NVMe/TCP endpoint attached to the IP interface.
   CDC IP Address | The Centralized Discovery Controller (CDC) IP address.
   CDC Port Number | The CDC port number.
   CDC Connection Status | The CDC connection status. Possible values are: Pending, Established, Failed, and Unknown.
   CDC state | The CDC state.
   mDNS state | The Multicast DNS (mDNS) state.

   The following controls are available, depending on the operating environment:
   - Create— Create an IP interface
   - Attach— Attach an IP interface to a NVMe/TCP endpoint
   - Detach— Detach an IP interface from a NVMe/TCP endpoint
   - Modify— Modify an IP interface
   - Ping Remote IP— Ping a remote IP interface
   - —Delete an IP interface
