traffic-shape rate 10000000 is only for traffic exiting the vlan, not internal vlan traffic, right?

I saw this: https://supportforums.adtran.com/thread/1383  and I have a question.  We have a symmetrical 10Mbps internet connection.  I think at times we may be exceeding that outbound.  At that time, I think my carrier may be dropping some packets. I want to throttle the internet connection (VLAN 666) outbound to 10000000 Bps so this sounds like it will work fine for me.  It seems like my router will buffer the excess instead of the carrier dropping packets.  Question.  I have several devices in this vlan public facing.  "traffic-shape rate 10000000" will only throttle traffic leaving that interface right?  Not the inter vlan communication between the devices on that vlan?  Thank you!

Hi curtc:

Thank you for posting your question in the Support Community!  Traffic shaping is per-interface.  In your example, egress traffic from interface vlan 666 (going out toward the WAN carrier) will be limited to 10 Mbps throughput.  Egress traffic from other interfaces will not be affected by traffic shaping on interface vlan 666, though it is possible to apply traffic shaping to them as well, if desired.

Traffic shaping is a great feature as implemented in AOS.  An ADTRAN router will attempt to gracefully delay traffic instead of simply dropping packets which exceed the rate limit.  Check out Configuring QoS in AOS‌ for additional info and config examples.  Depending on the type of units you manage, Configuring Enhanced Ethernet Quality of Service (EEQoS) in AOS‌ may also be a useful way to go--especially when using sub-interfaces and VLANs.

Best,
