Gig to 100mbs connection

Is there any problems connecting a gig port to and 100mbs port, and are there any config that need to happen for it to work

Re: Gig to 100mbs connection

If both ports allow autonegotiate and support 100mb over copper then there should be no problem. they should negotiate to 100mb, if the gig port is gig only then you will not be able to interconnect with a 100mb port.

Re: Gig to 100mbs connection

I recommend setting to auto-negotiate unless there is some prefailing reason not to. I have had issues with port disabling themselves we 10/100/1000 server NICs or plugged into Cisco 10/100 modules. If auto-negotiate is enabled you will be able to review logs to determine any issues. If you enable non-negotiate you will not get any definitive port error logs.
