Cook County Bureau of Technology IT Network Repair

Fixing a Virtual Local Area Network Problem


Cook County is the second largest county in the U.S. and home to more than 40% of all the residents in Illinois. The Cook County Bureau of Technology (BOT) plans, develops and maintains enterprise technology services and provides cost-effective and easy-to-use services for residents and County employees. BOT handles enterprise technology procurements for all County government branches and offices, which share a wide area network (WAN), telecom, data centers and multiple enterprise contracts.

BOT hired Level-1 to find and resolve a virtual local area network (VLAN) communication issue between load balancers and three virtual servers within their Dell virtual environment. Level-1 assessed their entire operating system and reviewed switch configurations on MXL’s for stacking, storage and local area network (LAN) as well as chassis and blade configurations. Level-1 built, tested and implemented a solution to extend VLAN through to MXL switches to ensure that the VLAN’s traffic is tagged both ways and communicates from the switch to the servers.
