Setting up a LAG with LACP between 3750-X and SG300-10
I am using a stacked pair of 3750-X switches as the core for a network, and there is one location where I need to hook up some devices where I would like to place a local SG300-10 and use a 2 port LAG between the SG300-10. When I look at status of the LAG (Etherchannel) on the 3750-X it shows as being up. When I look at the status on the SG-300 it appears to be up. When I unplug and plug the ethernet cable I see the VLANs on the LAG go up and down from the SG300 log.
%AAA-I-CONNECT: New http connection for user cisco, source 192.168.56.112 destination 192.168.56.206 ACCEPTED
%AAA-I-DISCONNECT: http connection for user cisco, source 192.168.56.112 destination 192.168.56.206 TERMINATED
%LINK-I-Up: Vlan 3
%TRUNK-I-PORTADDED: Port gi9 added to Po1
%STP-W-PORTSTATUS: gi1: STP status Forwarding
%LINK-I-Up: Vlan 2
%LINK-W-Down: Vlan 3
%LINK-W-Down: Vlan 2
%TRUNK-W-PORTREMOVED: Port gi9 removed from Po1
I have set a couple of ports on the SG-300 to be untagged on the the VLANS and I do not get IP addresses assigned via DHCP, I plug in something statically addressed with that VLAN, and I cannot reach it. I also cannot reach the admin web pages for the switch via the trunked interface. The same configuration on the 3750-X works with the Gigabit port on Catalyst Express 520 so I think the 3750-X is configured properly.

Any thoughts on where I might have gone wrong would be greatly appreciated.
