Cisco 3750 setting speed to 100 shuts down port
Posted on 2014-02-17
Hi everyone, I have what I believe to be an interesting situation. I have a 3750 switch that I'm trying to hard set the speed to 100 on a port that I have a Cisco C20 VTC endpoint connected to. The IOS I'm running on the switch is 12.2 (55) SE8. Whenever I enter the command "speed 100", it shuts down the port. If I set the speed to "auto", it will bring it up but only to 10mb. I don't have port security set and the config is as basic as it gets.
switchport access vlan 15
switchport mode access
