vde_switch doesn't have -tap option (mac os x)

[TheFausap]

Hello,

I installed vde package (2.3.2) using brew under Mac OS X Big Sur 11.5.2
I used before vde under Linux, but I tried the same approach with Mac OS without success. The main issue is related to the '-t' option that seems is missing.

sudo vde_switch -t tap0

vde_switch: unrecognized option `-t'
Usage: vde_switch [OPTIONS]

Report bugs to info@v2.cs.unibo.it

If I run also a man vde_switch, I have

vde_switch [ -hub ] [ -sock commdirpath ] [ -mod octal-mode ] [ -group NAME ] [ -tap interface ] [ -daemon ]

but even if I try with '-tap', I have the same error.

Please, can you help me?

thanks

Not a MacOS user, but it could be that the brew package has been compiled without tap support.

• Could you try compiling vde from sources using configure/make and see if the tap support works?
• Is there a /dev/tap0 and Library/Extensions/tap.next in your system? By looking at our autoconf scripts, it looks like there might be an extra package dependency such as tuntaposx?
