you only need to add the vlan configuration to the port channel interface it will apply to all physcial interfaces that are members of that group ________________________________________ From: Murphy, William [EMAIL PROTECTED] Sent: Wednesday, October 24, 2007 5:16 PM To: Mike Louis; Nate Carlson; [email protected] Subject: RE: [c-nsp] Problems adding VLAN's to portchannel trunk We have an HP Blade Center also and our switch is hard coded to on...
