SG 2100 - LACP
Is it posible to configure a LACP Link Aggregation on two of four LAN physical ports from the SG 2100?
Do I have to delete de LAN interface? Also I've read from pfSense that good practices says better no mixing tagged and not tagged networks on a LACP from pfSense. Do you know something about this? So, if the thing is that the 2100 doesn't allow LAG LAN ports, is it the 3100 capable? If the 2100 is capable, how can I configure the LACP? Cause I don't find more interfaces on lagg tab.
No, that's not possible. The on-board switch does not support LACP lagg. It can do a load-balance lagg but that does not provide link redundancy.
The SG-3100 has the same switch but because it has two individual interfaces you can use those to create an LACP LAGG and then use the switch ports for whatever other interfaces you might need.
