  • 1.  AVB, GPTP and Meyer Galaxy processor issues

    Posted Aug 08, 2025 02:19 AM
    Hello all

    This is quite spesific question but is there somebody who has used Meyer Galaxy AVB-connecting audio processors with 6300SR switches. I know Meyer has ”certified” Netgear devices to be the one to use but I also know that ng uses standards quite ”flexibly” every now and then.

    I have gPTP sync problems and some stream drop problems without having lots of traffic between devices (around 30-40mbps in three ports). QoS is configured as recommended and AVB/msrp itself should be ”on”.

    I see PTP clock data, switch is properly configured into dotAS profile as boundary clock and I can see clock packets with Trackhound but I don’t know howto properly debug gPTP or AVB further.

    Does somebody have some real world experience with this one?

    This A/V networking is quite specific, and my experience is that knowledge is limited to people that actually used it. I haven't used it myself, so can't really help.

    If you want to do more investigations yourself, there are quite a lot technical videos here that cover PTP features in different AOS-CX versions.

    Otherwise, unless someone with practical experience reading this, maybe it's best to work with TAC and start troubleshooting what's going on and if it's related to the switch or other equipment.

    Hello Herman,

    I kind of knew (and afraid) that there is not that many people there who has used AVB with Aruba devices at first place so this was kind of shoot in the dark question...

    I assume you have the license for AVB  ? 

    I would raise a TAC case but see some suggestions below

    For QOS please apply the following with Q4 being strict

    switch(config)# qos queue-profile avbQprofile

    switch(config-queue)# map queue 4 local-priority 7

    switch(config-queue)# map queue 4 local-priority 6

    switch(config-queue)# map queue 3 local-priority 5

    switch(config-queue)# map queue 3 local-priority 4

    switch(config-queue)# map queue 2 local-priority 3

    switch(config-queue)# map queue 2 local-priority 2

    switch(config-queue)# map queue 1 local-priority 1

    switch(config-queue)# map queue 0 local-priority 0

    switch(config)# qos schedule-profile msrp-profile

    switch(config-schedule)# strict queue 4

    switch(config-schedule)# dwrr queue 3 weight 1

    switch(config-schedule)# dwrr queue 2 weight 1

    switch(config-schedule)# dwrr queue 1 weight 1

    switch(config-schedule)# dwrr queue 0 weight 1

    switch(config-schedule)# exit

    switch(config)# apply qos queue-profile avbQprofile schedule-profile msrp-profile

    Also best to use the "automagic" :) avb configuration which will use the vlan 2 as the default AVB VLAN

    (config)avb

    (config-avb)enable

    make sure vlan 2 is allowed on the trunks.

    enable PTP and MSRP on ports

    End point (clients)  must also be trunk ports

    i.e

    (config-if-1/1/5,1/1/27)#no shut

    (config-if-1/1/5,1/1/27)#no routing

    (config-if-1/1/5,1/1/27)#vlan trunk native 1

    (config-if-1/1/5,1/1/27)#vlan trunk allowed 1,2

    (config-if-1/1/5,1/1/27)#ptp enable

    (config-if-1/1/5,1/1/27)#msrp

    (config-if-1/1/5,1/1/27)#exit

    some trouble shooting commands

    show msrp streams

    show avb int br

    show avb domain

    Hello Kamal,

    At the moment AVB is "standard feature" in 6300M multirate switches so no need for additional licenses (thank god for that :D)

    On top of above configuration there is need to configure gPTP boundary clock but all was already fine BUT it seems that there is need to configure  mvrp too into avp ports (I think it creates dynamic vlans used by avb devices?!?)

    After adding mvrp it seems to work but sound guys has time to debug it in next week.

    OK at least you have made some progress :-)

    by running 

    (config)avb

    (config-avb)enable

    also sets up gptp for vlan 2 "automagicaly "

    or you can set up the profile as you did

    For AVB a feature pack  (license) is required you should check with your account team  about this whom can confirm

    "show feature-pack" can confirm this

    Hello Kamal,

    You are right, avb needs license to use but license seems to be enabled anyway without advanced pack...

    I will contact my sales rep now.

    Thank you for your help.

    Sometimes features that are covered under a license pack are 'early available' without the enforcement. The fact that you can use the features without the advanced license pack doesn't necessarily mean that the license is not needed, or that the license will not be enforced when you upgrade the firmware in the future.

    Something similar happened with the application visibility feature.

    Okay, Today was successful to resolve this issue!
    I will lend Kamal's previous post here to avoid double writing.

    First: Make sure you don't use vlan 2 to any other function than avb (see below..)
    Second: While it seems that there is no easy way to change default AVB vlan in actual devices (Talkers and Listeners) stick to the default vlan 2 in avb configuration.
    Third: If you have mvrp enabled in switch make sure there is no connected avb devices in switch. Check "show vlan" that vlan 2 is not listed as dynamic or static vlan. If vlan 2 exists, find out why and get rid of it before continuing to next steps.

    Then actual configuration:

    Kamal's suggestion for Queue & Scheduling configuration works well:

    switch(config)# qos queue-profile avbQprofile
    switch(config-queue)# map queue 4 local-priority 7
    switch(config-queue)# map queue 4 local-priority 6
    switch(config-queue)# map queue 3 local-priority 5
    switch(config-queue)# map queue 3 local-priority 4
    switch(config-queue)# map queue 2 local-priority 3
    switch(config-queue)# map queue 2 local-priority 2
    switch(config-queue)# map queue 1 local-priority 1
    switch(config-queue)# map queue 0 local-priority 0
    switch(config)# qos schedule-profile msrp-profile
    switch(config-schedule)# strict queue 4
    switch(config-schedule)# dwrr queue 3 weight 1
    switch(config-schedule)# dwrr queue 2 weight 1
    switch(config-schedule)# dwrr queue 1 weight 1
    switch(config-schedule)# dwrr queue 0 weight 1
    switch(config-schedule)# exit
    switch(config)# apply qos queue-profile avbQprofile schedule-profile msrp-profile

    Also best to use the "automagic" :) avb configuration which creates proper "ptp profile dot1as" and will use vlan 2 as the default AVB VLAN.

    (config)avb
    (config-avb)enable

    Talkers and Listeners are trunk devices containing separate configuration (let's use vid 10) and avb (default vid 2) vlan's so make sure configuration vlan is native and in port and vlan 2 is allowed on the trunks.

    i.e

    (config-if-1/1/5,1/1/27)#no shut
    (config-if-1/1/5,1/1/27)#no routing
    (config-if-1/1/5,1/1/27)#vlan trunk native 10
    (config-if-1/1/5,1/1/27)#vlan trunk allowed 2,10
    (config-if-1/1/5,1/1/27)#ptp enable
    (config-if-1/1/5,1/1/27)#msrp
    (config-if-1/1/5,1/1/27)#exit
    (config) wr me

    Now switch should be ready to connect avb devices to ports 1/1/5 & 1/1/27. 
    If you use redundant avb connection with two separate switches connected to each other, make sure that primary & secondary vlan 2 does not see each other!! (Otherwise you will get routing issues and great amount of config program weirdess ;) )
