Link up time for an SN7000 Spectrum switch and ConnectX-5-Ex

Hi,

I would like to know, how long will it take for an Spectrum switch to go from INIT to Active state. Is it normal that it takes around 10 sec? After consulting the ONYX RN https://networkingdownloads.nvidia.com/custhelp/Non_Monetized_Products/SwitchesandGateways/MellanoxOnyx/Onyx_ETH_v3_10_4206_RN.pdf, we could find some Known issues with Link up time for Spectrum-2/3, but not clear for Spectrum SN7000 switches. Note that cables used are 2M/3M Mellanox Copper QSFP-28 cables. It takes around 10 sec for the Link to be established with both the cables. Is this behavior normal?

Hi,

Usually things like this is firmware related. I suggest to update both the switch and HCA to the latest versions. If the issue persist, than it means that it is normal behavior.
