I am installing a 5508 for the first time using a ESW 540 switch.  I can not gain access the 5508 if I asign a vlan to the management port.  I have to leave it as untagged to gain access.  I will need to have two vlans on the wireless AP's.  The AP's, LAP1142, just keep going up and down.  Is this a workable combination?  I was told i needed to trunk the connection to the 5508.
