QoS on SPA 2102 using VLAN

I'm trying to configure quality of service on a SPA 2102 using VLAN tagging.

But using wireshark I see that the packets exiting the ATA don't have the TOS volue correctly set.

Is possible to give different priority to Data and voice using VLAN tagging?

 

Thanks

Re: QoS on SPA 2102 using VLAN

I Believe the QOS Value on The SPA are set to default and Its not possible to be change. I was able to find other forum sites for the SIPURA default  values.

 

SIP TOS/DiffServ Value: 0x68 
RTP TOS/DiffServ Value: 0xb8

ToS 0xb8 = 10111000 = 184
(802.1p) = 101 = 5
(DSCP) = 101110 = 64

ToS 0x68 = 01101000 = 104
(802.1p) = 011 = 3
(DSCP) = 011010 = 26

 

I Hope This helps

OK,

but I tried to sniff the VLAN traffic and I see in the priority field of the packets the value 0 and not the default value..

Why?

 

Thanks
