Before configuring your Cisco 9336C-FX2 switch, review the following considerations.
Support for NVIDIA CX6, CX6-DX, and CX7 Ethernet ports
If connecting a switch port to an ONTAP controller using NVIDIA ConnectX-6 (CX6), ConnectX-6 Dx (CX6-DX), or ConnectX-7 (CX7) NIC ports, you must hard-code the switch port speed.
(cs1)(config)# interface Ethernet1/19 For 100GbE speed: (cs1)(config-if)# speed 100000 For 40GbE speed: (cs1)(config-if)# speed 40000 (cs1)(config-if)# no negotiate auto (cs1)(config-if)# exit (cs1)(config)# exit Save the changes: (cs1)# copy running-config startup-config
See the Hardware Universe for more information on switch ports.
25GbE FEC requirements
FAS2820 e0a/e0b ports
FAS2820 e0a and e0b ports require FEC configuration changes to link up with 9336C-FX2 switch ports.
For switch ports e0a and e0b, the fec setting is set to rs-cons16
.
(cs1)(config)# interface Ethernet1/8-9 (cs1)(config-if-range)# fec rs-cons16 (cs1)(config-if-range)# exit (cs1)(config)# exit Save the changes: (cs1)# copy running-config startup-config
