Problems with CARP, VLANs and em driver

[Mathieu CHATEAU]

Hello Eivind,


obviously you have updated your conf file to get em0 instead of xl0 ?

does each other ping the other ?

does the master stay in init or become master thinking he is alone ?

the slave is now master since you changed your card ?
