Hi,Jan: I met the same problem as you post on vpp mailing list.
I create vpp tap interface as below script shown: #!/bin/bash for i in {1..1000} do sudo vppctl tap connect lstack${i} done But,when I got to tapcli-502,fail to show: tap connect: Couldn't open /dev/net/tun then,I use ulimit –n 4096 to raise the number of open files,but it doesn’t work for me. Could you give an advice to me? Thanks, Olympus
