We experienced something very odd when we moved an EPC from being directly connected to a router to being connected via a switch, with separate ports for bearer, management, and PDN. Even with no overlapping port VLANs on the switch, the EPC refused to work when connected via a switch, and we had to consolidate VLANs to one port. Apparently that was an unsupported configuration. We'll do a LAG for all trunks when that is available. In a perfect world we could do multiple LAGs, one to each of two separate switch/router combos, to eliminate SPOF… -- Jeremy Austin (907) 895-2311 (907) 803-5422 [email protected] Heritage NetWorks Whitestone Power & Communications Vertical Broadband, LLC Schedule a meeting: http://doodle.com/jermudgeon
