# Attach an NVMe/TCP endpoint to an IP interface

Unisphere provides monitoring and management for Non-Volatile Memory Express (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 NVME tab to open the NVMe dashboard.
3. Click NVMe/TCP Endpoints (Attached or Unattached).
4. Select an NVMe/TCP endpoint and click Attach.
5. Select whether to use an existing or new IP interface, and do one of the following depending on your selection:
   - Existing:
     - Select an IP interface from the list.
   - New:
     - Select a director and port combination from the drop-down menu.
     - Type a value for the IP Address. You specify the IPv4 address in dotted decimal notation. You specify the IPv6 address in colon-hexadecimal format.
     - Type a value for the Prefix. You specify an IPv4 prefix length value in the range of 1-30. You specify an IPv6 prefix length value in the range of 1-128.
     - View the value for the Network ID. Value that is displayed is based on the existing target selection.
     - Type a value for the VLAN ID. Valid values range from 0 through 4094. This setting fails if same VLAN id is used for more than one IP interface on a specified NVMe/TCP Protocol enabled physical port.
     - Optional: Type a value for the Max Transmission Unit. The default value is 1500. Valid values range from 1200 through 9000.
     - Optional: Select the Use Jumbo Frames checkbox to apply jumbo frames to the IP interface.
     - Optional: Click to delete an IP interface.
6. Click OK.
   If you switch between the New and Existing selections, the system applies only the changes from within your last selection.
