I have a basic question regarding two 3750G switches I would like to connect using fiber.
I have the 2 Twingig modules converter available for each switch.
I need to know my requirement to connect these two switch by their uplink.
I have already on my list:
1 SFP module (GLC-SX-MM) the question is how many SFP modules will I need to connect these 2 switches as each switch has 2 Twingig port (hence 4 SFP ports available). since each Twing Gig port has 2 SFP module.should I use 1 Twin Gig module and ordre 2 SFP modules (GLC-SX-MM) for each switch (hence 4 GLC-SX-MM )for the connection to work ?
Thanks for your guidance and related documentation you'll be giving.
According to the following Cisco document, the Twingig converter module can be used with up to 2 SFPs; which would seem to indicate the use of 1 SFP in a Twingig converter module is supported.
You could install 2 SFPs per switch and run EtherChannel to gain additional uplink bandwidth.
