<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>Not sure if it would fit your need (or even work due to the multiple PVC’s), but could you apply a inbound CBFWQ on the Ethernet interface of the device? You could at least make sure that voice traffic is prioritized before being passed on to the other interfaces and then sent out to the FR cloud. The only issue is that you couldn’t do it on a per-interface basis, but it may still help as you could segregate voice from everything else.<BR>

<BR>
well..<BR>
<BR>
<BR>
1. yup..i trid everything, including CBFWQ, LLQ, FRTS, GTS, but nothing works in the scenario where IP address is on BVI and ofcourse everything works when IP address is on PVC subinf<BR>
2. i didn't try that but as i can see qos pre-clasify isn't supported on BVI interface - actually we just need to enable QoS on the egress of branch office router and enable priority for voice for example, what happens in FR cloud isn't important in this moment<BR>

Two quick questions/suggestions:<BR>
1) Did you try applying CBWFQ on a per-PVC basis (looks like you did and it did not work). That is, configuring a service-policy within a Frame Relay map-class, and then applying the map-class to the VC: <a href="http://www.cisco.com/en/US/tech/tk543/tk545/technologies_tech_note09186a008009489a.shtml">http://www.cisco.com/en/US/tech/tk543/tk545/technologies_tech_note09186a008009489a.shtml</a> <<a href="http://www.cisco.com/en/US/tech/tk543/tk545/technologies_tech_note09186a008009489a.shtml">http://www.cisco.com/en/US/tech/tk543/tk545/technologies_tech_note09186a008009489a.shtml</a>> <BR>
2) Second possibility I can think of would be to try using qos pre-classify command on the virtual interfaces (this, however, may or may not help over the F/R cloud)</SPAN></FONT></FONT><FONT FACE="Arial"><SPAN STYLE='font-size:11pt'>.<BR>

hi group..<BR>
<BR>
<BR>
<BR>
according to TAC engineer who talked with colleague of mine cisco doesn't have solution for next scenario..<BR>
<BR>
<BR>
in my country TELCO offers L2VPN over frame-relay network as well as over ethernet..<BR>
<BR>
<BR>
so, according to cisco we cannot offer QoS solution for those customers who still use FR as access to L2VPN..<BR>
<BR>
<BR>
so the issue is in branch office WAN router..<BR>
<BR>
the problem occurs since we need to create interface BVI on every branch router and assign ip address to it instead of frame-relay serial subinterface..<BR>
this is a MUST, beacuse of frame-relay encapsulation on the FR access, and central office understands only ethernet frames..<BR>
this way we're bounding FR to eth..<BR>
<BR>
so, we cannot apply LLQ or CBWFQ or GTS to interface BVI, it's not supported..<BR>
<BR>
<BR>
also, when we appy it to frame-relay subinterface ( which has all the configuration like classic FR interface except the fact that belongs to bridge-group and hasn't ip address ), it doesn't work..<BR>
<BR>
any thoughts how to overcome this..<BR>
<BR>
although i'm not shure it can be helped..<BR>
<BR>
<BR>
thanx..<BR>
<BR>
<BR>
regards..<BR>
