Link aggregation for redundancy

I am looking at a means to give me redundancy for my trunk port on a 5324.  Link aggregation can't be set up on ports if they are members of a VLAN or if the port is set to trunk.  Is there some means of ensuring redundancy for the trunk port?

    Havn't got access to a 5324 at the monet, but I would try this ( assuming I've understood your question correctly )
     
    If you want to connect 2 X 5324s toegther with an aggregate, and use that aggregate as an 802.1q  trunk then thats no problem.
     
    Lets say ports 23 & 24 are LAG 1 on each switch.
     
    Configure ports 23 & 24 as trunk ports.
     
    Configure ports 23 & 24 to form LAG 1 on each switch.
     
    Tag LAG 1 into all of the VLANs you want to trunk between the two switches.
     
    Connect the switches together........

    Unfortunately the 5324 is connecting to a Cisco 6513.
     
    If I set the two ports, in this case 23 & 24, to LAG group 1 and then try to  change them to Trunk - or vice versa - I get an error message indicazting that it can't be done because it is a member of a LAG.
