For ports with multiple settings they need to be configured per the fpc and port location per platform. Looks like the general command on the QFX is like this
set chassis fpc slot-number port port-number 25G
You need to find your specific model and commands here.

After the port is enabled xe is used for 10G ports and et is used for all higher speeds. The top of the document outlines how the three numbers in the interface are determined for fpc/pic/port on the switch.

Yes that seems to get things talking, thank you. However it is defaulting to 10G (ten).
How do I go about increasing the port speed to 25G.
The SAN and hosts both have 25G ports.

For a set of ports to be a simple layer 2 untagged access domain you would need two steps.
Create the vlan
set vlans <vlan-name> vlan-id <vlan-id (1..4095)>
and add all the ports to the vlan in access mode
set interfaces ge-0/0/ <port#> .0 family ethernet-switching interface-mode access vlan members <vlan-name>
The tagged process is similar and both are outlined here.

I am new to JunOS and the Juniper line of switches.
I selected a QFX5120-48Y to use as the switch for a SAN solution, very basic with a 6 ESXi hosts and a local SAN device. I am not having any data flow from the ESXi host to the SAN through the QFX.
There is no doubt I do not have the correct configuration on the QFX to facilitate traffic. At this point I would be just fine with a non-VLAN configuration to get one of the hosts to be able to connect to see the SAN. I am unable to ping from the ESXi adapter to the SAN.
At this time I just need the commands to config the QFX to pass the traffic.
Thanks much,
Keith
