Anyone familiar with DLC connecting back to a AS/400. We seem to be having some really weird intermittent issues with it. Nodes on the LAN seem to intermittent loss connection then regain it. Network consists of 4 Cat 5500 with RSM doing VLAN routing. Nodes on the same segment as the 400 have issues also. Any idea's? Packet size? Segment? This problem starting happening after we had to install a NEW rsm. Rsm ver.
