Hello,
I'm simply trying to create an LACP link between a SG500 and SG500X. The problem is on the SG500X which is the new switch I'm setting up - there are already other switches using the SG500 with an LACP link just fine, just this SG500X is giving me problems.
I have 4 links from the SG500 configured for LACP that I will be using with the SG500X, although the ports I want use 33-36 show as 'non-candidate' on the SG500, why I don't know.

When I go over to the SG500X and setup the port-channels and such, the links steadily keep saying the LACP ports are inactive. When I look at one of the ports setup for LACP, I noticed is has no VLAN information.

None of the switch ports on either end are shutdown.
I can't ping my GW IP on the switch or the management IP on the switch, from the actual CLI interface. The only time I can at least ping the local interface on the SG500X switch is if I have a different laptop setup on a port for 'access mode', then I can ping the actual management IP address of the switch. But of course this laptop would be connected directly to the SG500X when this works.
What am I missing here, do I need to set this up only via the Web GUI or what? This would easily work on any other Cisco switch.
Additionally, I only added one link port channel on the SG500X and still NO joy.

I know this is an old string but since I started it I felt appropriate for me to begin it again. I'm still stuck using trunk ports only between my SG500 and SG500X.
I have what is my edge switch (SG500) connected to a cisco core with LACP set to 'auto' - that works fine.
I then have an SG500 connected to a SG500X but I can't seem to get port-channels working between the 500 and 500X. On the 500 I have 4 ports setup using the same port-channel 1 back to my core switch. I wanted to create 2 more ports on the 500 using port-channel 1 and then connect those to my 500X.
I have connected 2 ports on the 500 and 500X together (starting with only one link first) and add those as "channel-group 1 mode auto". Then I connect a laptop to the 500X using an IP on one of my VLANS I'm trunking and I can never ping that laptop, so I know the port-channel is not passing traffic. If I got back to a simple trunk port between the switches I can ping just fine.
I seem to have still not figured out the trick to getting port-channels to work between these switches.
I have setup both the 500 and 500X port-channels for both "on" and "auto" and it seems to just not be working.

5 years to late but ...
"I wanted to create 2 more ports on the 500 using port-channel 1 " - You cannot re-use port channel 1 to a different switch.
You would need to create port channel 2.
I also don't see you actually configuring the ports as trunk e.g.
interface port-channel 2
switchport mode trunk
