I administer a network at a school where we have a Ruckus ZoneDirector 1112 controlling 13 Ruckus ZoneFlex Access Points of varying types. A while ago the Netgear ProSafe GS724TP PoE switch failed so I replaced it with a HPE OfficeConnect 1920S 48G 4SFP PPoE+ 370W switch (JL386A). At this point the ZoneDirector which was connected directly to the new switch lost communication with all of the Ruckus ZoneFlex Access Points.
I was able to reconnect some of the access points after much testing by moving the ZoneDirector to a second cabinet connected directly to a Cisco SG200-10FP PoE switch. Any access points connected to the Cisco switch were able to communicate again with the ZoneDirector. All other access points are either connected directly to the new HPE 1920S switch or to an additional Netgear PoE switch (on a different floor) that is itself connected to the HPE 1920S switch.
Basically, the HPE 1920S switch seems to block all communication between the ZoneDirector and the ZoneFlex access points but I cannot figure out why this would be or how to rectify it other than replacing the switch with a different model.
Does anyone here know of any settings that can be applied to the 1920S that will allow this communication to take place?
