Greetings,
I have a network topology that is using 5 Stratix 5400 switches that has 2 separate DLR networks configured. The DLR ports are set to only allow 1 specific VLAN for each ring. Both VLANs have the same IP address range but are segregated by using 255.255.255.128 for the subnet.
DLR 1 has no ETAPs but does have 5 Stratix 5700's in the network and I've had no issues throughout testing various network breaks. Stratix switch 1 is set for supervisor and Stratix switch 2 is set for backup. DLR 2 has 6 ETAPs in different segments of the rings network. An EN2TR is the only set supervisor and ALL ETAP dip switches are set to off. When breaking the DLR 2 link ports between Stratix switches, the network functions as expected. When breaking the link connection at any ETAP in the ring, the network initially functions as expected, 50 seconds later the network momentarily loses connection to ALL ETAPs for about 10-15 seconds, then reestablishes connection which then remains healthy.
I've since had to change the topology of the DLR 2 network to not go through the Stratix 5400's by using more ETAPs which now allows the network to function as expected when testing breaks in the ring. I then tried to use the Stratix 5400's non DLR ports as unmanaged switches to plug the DLR 2 ETAP's device port into which when doing this with 1 ETAP and 1 Stratix, functions fine. When doing this with a 2nd ETAP and a 2nd Stratix, the DLR 2 network becomes unstable and I begin to see erroneous communication losses.
Thanks for any insight to the issues I may be experiencing.
