Main purpose

Operation of the central network infrastructure connecting all Jade University locations and forming the technical foundation for all IT services.

Description

The university network connects the three locations Wilhelmshaven, Oldenburg, and Elsfleth and provides fundamental infrastructure services: DNS name resolution, NTP time service, network monitoring, and wired network authentication (Software-Defined Access). New devices in PC Network System (WORK-PCVS-1.0) are delivered fully preconfigured. Department and lab servers can be integrated into the network infrastructure after consultation with the IT center (COMM-HELPDESK).

Please Note:

SDA configuration for Windows (existing devices):
1. Services → 'Wired AutoConfig' → Start type: Automatic
2. Ethernet adapter → Properties → Authentication:
- Enable IEEE 802.1x: activate
