Hi Neale, I will attempt this on this latest. Yes ARP cache flush is one option as that seems to help out , I find that arp flush per interface requires a walk through all the arp entries and identify those that are specifically on the interface in question. Not sure whether I am missing somethin

[vpp-dev] fixing VLIB_BUFFER_TRACE_TRAJECTORY

2021-02-04 Thread Benoit Ganne (bganne) via lists.fd.io
Hi all, I'd like some feedback about the VLIB_BUFFER_TRACE_TRAJECTORY debug feature in VPP. The goal of this feature is to save the nodes traversed by a buffer in the buffer metadata (opaque2->trajectory) for debug purpose. As far as I can see, it is broken as soon as the buffer is copied/clone

This is good information. Can we take a step back and approach this from a different perspective? Why do we actually need scapy? The general process is that we use scapy to create a separate pcap file that is fed to the vpp packet generator. If we instead create named pcap files that we pre-packag

Few quick comments and links. Turns out GPLv2-or-later is not by itself compatible with Apache [2], we need to use GPLv3 (which is compatible with both). The questions on dynamic linking are still open [3] [4] [5]. We probably need to distinguish several Programs available from VPP repository. V

Hi Rupesh, 19.08 is no longer supported, please upgrade. The down side of flushing the ARP cache on link down is that the ARP cached gets flushed 😉 you have to rebuild it when the link comes back up, this takes time. Otherwise I see no issue with doing so. The adj walk is there to remove that

Hi Neale, This is version 19.08. Meanwhile, based on whatever I understood from the discussion so far, I experimented by adding a link down function that does an arp flush on the respective interface which resulted in arp delete and subsequent adj nbr removal. This seems to provide the desired re
