You are missing a couple of things. I'm assuming you are running a single switch and will be doing no stacking at all. I'm assuming your vlan is untagged, it is vlan 1 and your are using 1/2/1 for your data port.Guys. Finally I got my hands on my ICX -6610-48p and it could not be different being a Cisco guy I'm having some trouble to configure the 2 rear stacking ports.
I want to use as a regular port to connect to my windows 10 box but no joy.
I'm using the fllowing hardware and cables:
NIC: MCX354A-FCBT 649281-B21 656089-001 VPI FDR 40GbE Mellanox from HP 544QSFP MCX354A-FCBT 649281-B21 656089-001 VPI FDR 40GbE Mellanox OEMFirmware | eBay
Cable: Netapp 112-00178 5M 16ft QSFP-QSFP External SAS Cable X6559-R6 from NetApp X 6559 R 6 SAS Cable 5 M QSFP for sale online | eBay
1) you need to disable the stack and reboot the switch
conf t
disable stack
exit
write mem
reload
2) you need to add the 40Gbe port to your vlan
conf t
vlan 1
untagged ethe 1/2/1
# don't forget to add any other ports (tagged or untagged) to vlan 1.
exit
exit
