Physical Interface with Multiple VLANS - Throughput?



  • We have a single physical LAN interface sub-divided into multiple virtual interfaces that use VLANs. We use PBR to allow traffic to flow between the various VLAN interfaces. I configured the traffic shaper last night for the LAN interface and I noticed that the "LAN" qLink queue is seeing a really high (up to 500Mbps on a 1Gbps interface) amount of traffic.

    That is explainable if it is because the LAN interface is seeing all the virtual VLAN interface traffic. Is that the case?

    Is there any way to determine what the top consumers of that bandwidth (by device IP is fine) are?



  • Is your LAN VLAN untagged?

    Squid would be really good for this action. Or CACTI could be used to show those stats.
