Re: [lng-odp] [ODP-DPDK] SpanningTree and block a port ?
Hi! Thank you very much for the answer! Regards Nicolas De : Brian Brooks Envoyé : mercredi 7 octobre 2015 15:49 À : Kury Nicolas; lng-odp@lists.linaro.org Objet : RE: [ODP-DPDK] SpanningTree and block a port ? Hi Nicolas, In your use case, a STP 'application' and a traffic generator 'application' need to be designed to run as separate processes that work together. Multi-process aside, odp_pktio_start/stop() is documented as a way to start/stop tx & rx on a packet IO interface. Depending on the implementation, this may be usable for STP. For MSTP, perhaps you could utilize the classification APIs to match on pktio + VLAN and drop for ingress blocking. However, the application would need to be aware of the spanning tree state to prevent transmitting packets destined for blocked ports. Note the API for polling link state: https://lists.linaro.org/pipermail/lng-odp/2015-September/015557.html Regards, Brian From: lng-odp [mailto:lng-odp-boun...@lists.linaro.org] On Behalf Of Kury Nicolas Sent: Friday, October 02, 2015 8:50 AM To: lng-odp@lists.linaro.org Subject: [lng-odp] [ODP-DPDK] SpanningTree and block a port ? Hi I would like to implement an application with spanning tree protocol. But can the application "spanningtree" stop and start a port used by another applications (exemple odp_generator) ?
