Etherchannel issue 2xSG30028P

Morning I am having issues trying to get a etherchannel form between two switches. the first switch says that the link is down and LACP is enabled and the second switch says that the link is up and LACP is disabled even though both interfaces show as up in the port administration page.

i have followed the following instructions but as yet have not had any joy

  • first set the two ports on each switch to trunk and only specify an untagged vlan (Vlan 1)
  • gone to the Link aggregation tab and added the two ports to a port group and ticked LACP
  • this shows up on both switches in port administration showing 1P
  • gone to port to vlan and then added all the rest of our vlans as tagged on the LAG

this should have then caused the switches to form the LAG in my understanding what am i missing? here are some shots of what ive done

switch 1

Switch 2
