Digital Partyline: Helixnet basestation not able to recognize each other on VLAN

Digital Partyline: Helixnet basestation not able to recognize each other on VLAN

Apr 09, 2019

The Ethernet switches we are using are the Extreme Summit X440 models.Here are the symptoms: We have three HMS-4X with ET2 modules connected to a network switch.We have some HRM-4X panels connected to the same switch.The panels can see the individual HMS-4X stations.The stations can't see each other.If we plug two base station ET2 modules together directly with a cable they can connect.The HMS-4X systems have firmware 2.0.63
Solution: Customer had success getting all helixnet basestations to recognize each other turning off IGMP snooping on the VLAN linking all the helixnet base stationsClear-Com recommends when using VLANs that you setup the VLAN to look like a plain / simple un-managed LAN segment
Solution update: Oct 2017
Ensure that ""block unregistered multicast"" is not set on Netgear / Extreme switches. This blocks traffic that should be allowed (mDNS, PTP)Helixnet uses mDNS to send out mainstation names and ip address for pairing of units .
