My customer is using a Arista switch capable of 100G. They are using supported 100G optics on the Arista side. We have placed NetApp optics (purchased from NetApp) on the NetApp side. Using an OM4 MTP(or MPO) cable to connect. Any traffic generated results on errors on the Arista switch side and very slow performance.
(I know…I am lacking some details like switch model and EOS version, I will share when I have that. I am hoping this can be answered more genericly)
As a test, the peer-link was replaced with the Arista supported 100G optics and the same cable running to the NetApp. Data was generated and no errors were seen on the Arista switch.
What I am asking, what is Arista’s response to the “best supported” port configuration to connect with 100G (SR) optics to a NetApp controller?
I see this all available:
100full Disable autoneg and force 100 Mbps/full duplex operation 100g Disable autoneg and force 100 Gbps/full duplex operation over 4 or 10 lanes 100g-2 Disable autoneg and force 100 Gbps/full duplex operation over 2 lanes 100g-4 Disable autoneg and force 100 Gbps/full duplex operation over 4 lanes
Which one setting should used? We have tried some of these and they seem to connect, just generate errors.
