We've got a 6509 [12.2(17a)SX1] connected to a couple switches in a HP c-Class blade chassis, which are Cisco 3020's [CBS30X0-LANBASE-M, 12.2(25)SEF1]. We've got an issue where we can't add a VLAN to the trunk without it going down because of VLAN mismatch while we are trying to add it to all three interfaces on each side (the two gig's, and the portchannel interface.] Here's what our config looks like; if anyone has advice on how we could add VLAN's to the allowed list without the links dropping, I'd love to hear it!
