MAB Switch

MAC Authentication Bypass is now the standard used by ITS for configuration of all UTP plugs for wired networks in offices. It makes a static configuration of the plug obsolete. Instead, the configuration will be done depending on the MAC address of a device that is plugged in.

Benefits

Any registered wired device can be plugged in to any UTP plug that is configured for docking in the CAB, CNB and UNG buildings, and will be connected to the defined network and get a static IP address via DHCP.

For our researchers this means that they can plug in their laptops in any plug in another office, meeting or seminar room, lecture room, etc. and get the same IP address as in their office.

Security Impact

Services that rely on IP-based security are not compatible with this. In particular NFS on Linux is not recommended to clients that are connected via MAB unless NFS4 with Kerberos security is used.

Server Rooms

All patch cables and UTP plugs in server rooms still have a static configuration. As a consequence, server room networks cannot be configured in offices.

Status

Migration is done building by building and group by group.

The CAB Building will be done in spring 2017.
