yes, they are. If you want to access me0 separately from the vme, you have to use the
"no-management-vlan"-keyword and configure separate ip addresses via shell and ifconfig. See the
Complete Software Guide and search for the keyword.

Technically*, vme puts all me0 into a kind of "family ethernet-switching"-mode, assigns an internal
management VLAN and sets up a vlan interface "family inet" with the configured ip address.

If you configure both vme and me0, "inet mode" and "ethernet-switching mode" collide.

Regards,

Malte
