7.4 Configure storage interfaces
Configure the interfaces for the storage connections. 25GbE interfaces 1/1/1 through 1/1/4 on both switches
are used in this example.
1. Provide an interface description.
2. Use the switchport mode trunk command to enable ports to carry traffic for multiple VLANs.
3. Allow the two storage VLANs, 1613 and 1614, on the trunk ports.
4. Set the MTU to its maximum size, 9216 bytes. This improves storage traffic performance.
5. Enable flowcontrol receive on and transmit off for best storage performance if DCB is not
used.
Note: Running the commands in the DCB configuration section of this guide, Section 7.7, will turn flow control
off if it has been enabled.
6. Configure ports directly connected to nodes, servers, or other endpoints as STP edge ports.
