For a larger company access layer switch,
There are two solutions.
1 There is a setting you need to make on the switch port for the ethernet sheild, because it does not auto negotiate speeds at all.
Here is my switch config , notice the speed is locked at 100. Duplex is set at FULL If you were to ask for a “locked down 100Mb Port”, the IT guys know what this means and could help out as well.
switchport access vlan 192
switchport mode access
- The other option is to buy a cheap switch from any local place that sells them. Plug it into the switch port and then plug the ethernet sheild into that cheap switch. The low cost switches are better at doing an auto negotiation of the uplink speed. for added security that you are buying the right low cost switch, look for a 100Mb one, not a 1gig one. Do NOT use some old router you have laying around, if the IT guys see it, they will shut you down and you’ll have to beg to get that port re-activated.
