Ok thank you. I ll wait for your answer.
Ps By the way linking 2 x 1930 via the sfp+ port between them (used a Ubiquiti DAC) seemed to work but I think more configuration is needed like -do I set jumbo frames on? 9000MTU instead of the 1500 default one? Is there a change of continues loop problems this way? Meaning do I have to set up STP? -Today I tried connecting a server via a 10Gbe DAC cable to one of the 4 sfp+ ports. It seemed to work meaning that the server could have net but don t have a way to check the 10g connection. Still this port too doesn t need configuration to see it as a 10g meaning MTU value again and any other possible option needed.
Hey,Thank you for being so patient while I worked with my team to provide you with the information requested. 1a. Is this done by connecting via a DAC cable one of the four 10gbe uplink ports of the current switch to the other one?
Yes, the DAC cable should work. For recommended DAC cables please refer to: https://www.arubainstanton.com/files/DS_AIO_1930SwitchSeries.pdf
1b. If yes do I need to enable jumbo frames for the specific port on both switches?
Jumbo frames config need not be mandatory as this is based on the need of deployment & application needs.
1c. Do I need some extra configuration inside the GUI? I've searched and didn't come up with anything. Probably I can connect the uplink port of the one switch to a regular port of the second but that would demand for a special sfp+ -> rj45 cable and dont feel like doing it this way (if that was a possibility all along)
There are no extra configurations needed to change these ports from regular to uplink or vice versa. In the case of multiple Vlans, they can be configured as trunks to carry multiple VLAN traffic.2.Are the 4 sfp+ ports dual purpose ones? Still didn't find in Gui anything like a software switch to allow to function as a regular or uplink port
They are dual-purpose and can be used as a regular or uplink port. No specific config is needed to configure as a regular or uplink port.
Generally termed as uplink as they have the highest data rate compared to other ports.
3.Can all uplink ports used independently (because there is a line that seems to connect the lower left - right 10gbe ports and thought that this means you can use one of them each time)
They can be used independently and the lines are to indicate that they are 10Gbe SFP+ ports.
Sample pic below.
4. I need to connect 2 servers between them (not by connecting them via their 10gbe network card) via the switch. There is need though, to be used the fast lane (10gbe) Since these 4 ports are uplink ports, can I use them and connect each server with a 10gb3 copper cable and afterwards they can see each other and also have internet access?
As long as the servers support 10Gbe cards they can be connected to the uplink port.5. In case I had an extra third 10gbe switch, then I could connect the 2 servers via their 10gbe network path to the switch. After that step, how that switch is supposed to to be connected with the Aruba switch (I mean which port) in order for both servers to have net access?
All three switches can be connected in daisy topology with servers, 1930 connected and for 1930 we recommend using any of the uplink ports.
