Contact Netgear Support for questions regarding network topology, switch models, configuration, troubleshooting or software updates. Netgear provides excellent support to its customers.
If you have an existing AOIP network built on a different brand of switches do not attempt to add the Netgear M4250/M4300 into the environment.
Programming
For the initial switch configuration please follow Netgear installation guide and user manual
Check/ update firmware
Before proceeding, check the Firmware Version shown on the Device Details section of the Overview page.
For the M4250, please make sure you are running firmware version 13.0.5.16 or higher
For the M4300, please make sure you are running firmware version 12.0.19.12 or higher
Check the Netgear downloads center to obtain current firmware for your switch model/port count
Assign Livewire+ Network Profiles to Ports
WARNING! DO NOT USE LIVEWIRE+ PROFILE!
December 2025
An IGMP issue with Netgear AV Line switches was discovered when connecting any two Studio Core/Edge, QOR.16 or QOR.32 products to ports configured with the Livewire+ profile. Until the issue is resolved, do NOT use the “Telos Alliance/Livewire+ AES67” profile. This issue is currently known to be a problem in the following firmware versions:
M4250 Firmware Version 13.0.5.16 and 13.0.5.20
M4300 Firmware Version 12.0.19.12 and 12.0.19.15
All customers using Telos Alliance products should simply use the AES67 profile instead until the issue is resolved. Note: no changes need to be made to your Telos products. You are not required to use PTP clock with this profile. You can still run all Livewire+ devices using the Livewire clock if you prefer.
The original instructions are still below with a temporary correction. This page will be updated once a fix is released.
In the current firmware releases, Netgear has included the Livewire+ Profile
Using the “AV Login”. Log in to the switch, and go to the Network Profiles page
Set the ports to use the “Telos Alliance/ Livewire+ AES67” “AES67”profile. Please see the Netgear user manual for more details regarding these profiles and how to apply them to the switchports
Please note - the “Telos Alliance/ Livewire+ AES67” profile will use VLAN 550. If dealing with multiple switches, make sure this profile is applied across all ports on each switch
Save changes to the switch
IMPORTANT! Please click the Save button at the top of the page to save the configuration to memory. Otherwise all changes will be lost if the switch is rebooted or powered down
That's it! If you have additional edge switches please repeat the steps above
If you are upgrading a previously configured switch. Likely the profile applied on the switch ports is “Audio AES67”. After performing the firmware updates, change these ports to use the Telos Alliance/ Livewire+ AES67 profile. While both profiles work well with Livewire. The specific Livewire+ profile adjusts addition switch parameters for best performance of Livewire traffic, but also supports AES67 traffic between products at the same time
Confirming IGMP multicast operation (optional)
The Telos Alliance/ Livewire+ AES67 profile automatically enables IGMP
Check that multicast groups table starts populating
On the left hand navigation select Multicast
The multicast group's table should start showing entries as more devices come online and start requesting Livewire or AES67 multicast streams.
Confirm that IGMP Querier Election is correct
If there are multiple Netgear switches installed we can confirm that the IGMP Querier is only running on one switch (core switch). We can confirm that the edge switches indicate IGMP Querier is coming from the core switch
On the left hand navigation click on Diagnstoics and then select Terminal
You will be prompted to log in from the CLI, use the same credentials used for the web ui
On the core switch, or central switch type in the command "show igmpsnooping querier detail"
For the VLAN defined in previous steps, VLAN 500 in this example we observe the "Operational State" shows "Querier"
(RED-CORE-RACK1)#show igmpsnooping querier detail
VLAN 550 : IGMP Snooping querier status
----------------------------------------------
IGMP Snooping Querier VLAN Mode................ Enable
Querier Election Participate Mode.............. Enable
Querier VLAN Address........................... 0.0.0.0
Operational State.............................. Querier
Querier MAC Address............................ 94:a6:7e:79:15:72
Operational version............................ 2
Operational Max Resp Time...................... 120
(RED-CORE-RACK1)#Repeat the same command but do this on any connected Edge switches
For the same VLAN, we observe the "Operational State" shows "Non-Querier"
Additionally "Last Querier Address" should equal the Management IP of the switch that is running the IGMP Querier
(RED-EDGE2-RACK1)#show igmpsnooping querier detail
VLAN 550 : IGMP Snooping querier status
----------------------------------------------
IGMP Snooping Querier VLAN Mode................ Enable
Querier Election Participate Mode.............. Enable
Querier VLAN Address........................... 0.0.0.0
Operational State.............................. Non-Querier
Last Querier Address........................... 10.0.2.5
Querier MAC Address............................ 94:a6:7e:79:15:72
Operational version............................ 2
Operational Max Resp Time...................... 120
