VLANs over LAGG vs separate interfaces
-
My current setup involves 4 vlans connected over a trunk connection to a switch, via a LAGG that includes 4 interfaces from my SG4860. Lately, I have been experiencing dropped packets on my voip vlan, and I have been wondering whether it would be better to take down the LAGG, and connect each vlan to the switch over its own interface. Would there be any benefit/drawback to doing so?

In terms of the packet loss - probably not. Unless one of those links has gone bad and you only see packet loss in connections that happen to use it.
A 4 way lagg (LACP I assume?) is probably a waste there, I would go down to 2 way. That would allow you to unplug one link at a time to see if either is bad.
You should also be able to see errors on the interfaces that make up the lagg. One will be a lot higher if it's a bad port/cable.Steve
