Hello.
We have a plan to connect Cisco Catalyst 3850 switch’s 1Gbps SFP port to Mellanox SN2100-BB2F QSFP port.
For this connection, we are going to connect them using NAM1Q00A-QSA and MC3208011-SX( SFP transiever).
I am not sure whether it will work fine or not.
I have read about QSA article https://community.mellanox.com/s/article/howto-use-mellanox-qsa and it says as follow, But I don’t know the meaning of “to plug another SFP+ to SFP into the QSA”.
" It is less common but possible to plug another SFP+ to SFP (10GbE to 1GbE) into the QSA and to reduce the port speed even to 1GbE.
Again, if it is a Mellanox Ethernet switch port, you must configure that manually.
For example, assuming the QSA was plugged into Ethernet switch port 1/1 and another SFP+ to SFP adapter was plugged into the QSA to reach 1GbE, run:
switch (config) # interface ethernet 1/1 speed 1000
switch (config) # configuration write
Question) If we plug MC3208011-SX into NAM1Q00A-QSA and configure “speed 1000” at that interface , will it works fine ? ( = we don’t need something needed to be purchased more.)
or do we need to purchase something like a speed convert adapter also ?
Thank you for your attention.
