I've been looking at the block diagram on the 1100AHX2 platform and was hoping someone has a clarification for me.
My question is regarding the capacity available for ports 11 - 13.
I know that the total routing throughput available to each AR8327 switch chip is 1Gbps
I know that 11 and 12 can act as an ethernet pass-through in case of failure.
Ethernet 13 is shown as a stand-alone link to the PCIe controller.
Questions: Are interfaces Eth11 - Eth13 each capable of carrying their own 1Gbps of traffic? The reason I want to make 100% certain is because the links to Switch1, Switch2, and Eth11 all depict 1000Mbit lanes, while the links to Eth12 and Eth13 do not denote any particular bandwidth.
What I would like to do is bridge ports 11 and 12 with "use-ip-firewall=yes" for transparent L3 QoS queueing capability, and I want to make sure that the system's bus has the capacity to carry a full gigabit of traffic between these ports. (If I were to CPU-bridge eth1 and eth2 for example, I would be limited to ~500Mbps due to the system architecture)
Thanks for any insights you may have.
