TL:DR; How do you enable PortFast on a SG250-26HP?
Full story:
I have just installed a DoorBird doorbell, that has a IP camera, and have some problems. It gets power, but cannot access my LAN. Looking into the logs, it connects (see later in mail) but immediately disconnects from the switch. Consequently, I cannot see the DoorBird on my router (IP or MAC address), as the data is not passed on from the switch.
It is connected to a Cisco SG250-26HP, that support the PoE IEEE 802.3af standard, as does the DoorBird doorbell. I read the DoorBird FAQ and saw that when using Cisco gear the following applied:
"In case you are running our devices in a network with a switch from CISCO Systems, please make sure to activate "PortFast" in your switch management. In case the function is deactivated, our devices cannot connect to the internet anymore after the daily routine restart."
The SG250-26HP does not have a PortFast function it seams, but it has something called "EdgePort" which according to a different forum I read, is similar. However I still cannot get it to connect tom my LAN even with EdgePort turned on.
I do however see reports in the Cisco log that the applicable port connects, then disconnects immediately, repeating every few seconds:
2018-Mar-25 18:11:47 Warning %LINK-W-Down: gi5
2018-Mar-25 18:11:47 Informational %LINK-I-Up: gi5
2018-Mar-25 18:11:47 Warning %STP-W PORTSTATUS: gi5: STP status Forwarding
This leads me to think there is not a hardware issue with cables or anything, but a software setting in the switch.
Can anybody help me enable PortFast, or an equivalent setting on the SG250-26HP?
