According to the vale.4 manpage: vale ports are named vale[bdg:][port] where vale is the prefix indicating a VALE switch rather than a standard interface, bdg indicates a specific switch (the colon is a separator), and port indicates a port within the switch. Bridge and port names are arbitrary strings, the only constraint being that the full name must fit within 16 characters. The manpage is confusing in that the name must be 15 characters plus the NUL character. Given the other limits, it looks like bdg can be up to 8 characters in practice. -- Brooks https://www.freebsd.org/cgi/man.cgi?query=3Dvale&sektion=3D4&apropos=3D0&ma= npath=3DFreeBSD+10.1-RELEASE --OXfL5xGRrasGEqWY Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAEBAgAGBQJXAuy7AAoJEKzQXbSebgfA/lAH/jPbh7qTw042FvDHgxIsxwCJ dGk5wsd7RgAIq5wYHeUMlHinaJrQYSKDNiyG0IZEKqmZANgv+o2bHpWdEtBW/EIV Ijt8xjHmDipWgG111R2Z0eCef0/33M/LiFQDFuqffjMQUQUs86UWKgVGLxdvIhNy XRteR9sVEks9LYIKZhbPe+fDIznvgPWC468vAlyDU3M/5HSlsl3fcGKSofo7HipY YwCX4Lp604HGt/r0iqXew6i78lSG0ObJrN/AGRHXnndJVHhi+Ow2+wXn8kyf+f6v mwpWo1VzH+sxSEYd0RtzLkMWcP/8BP7LAn97zyhUE3zDZOOXLUillEpIz/ra5Uc= =xlla -----END PGP SIGNATURE----- --OXfL5xGRrasGEqWY--
