Gies --- (In reply to Eugene Grosbein from comment #6) > Addition of first member to the bridge is quite different from addition o= f others. Why do you think it interferes with traffic flow every time? Mostly because I could not find any documentation regarding this so all I h= ad to go by was what I observed and it never occurred to me to try a second or third interface after seeing the problem with the first. The actions/commands in the initial bug report, along with a diagram of the setup, and hardware specifications. The ill effect is losing network connectivity for a few seconds, for a serv= er that can be quite problematic. Perhaps I'm approaching this all wrong and trying to squeeze s square peg through a round hole. Are bridge/epairs the wrong tools for vnet jails, is there a better alternative? --=20 You are receiving this mail because: You are the assignee for the bug.=
