It would be great if there was a network test tool like ping for o11s. something like a "mping" (mesh ping) or "tracepath" (traceroute for layer2)
it could use a increasing mesh_ttl value as long as the last node would reply pack to the source when it drops a packet do to mesh_ttl being surpassed. this is how traceroute works at layer 3, it ICMP pings a host with a ttl of 0 to find the first hop, then a ttl of 1 to find the next, etc. A mesh ping could do the same with a mesh_ttl watching for the mesh node to reply that it has dropped the packet at each increase of mesh_ttl. I would like to be able to get a reply from each node along a path, to test and determine exactly the path through the network from one node to another without having to log into each consecutive node manually and look at the mpath table. How hard would something like this be to implement? Or let me know if there is already something available. I looked at arping already, and it won't help. David Fulgham
