Networking

Switching

Network Segmentation

Issue: Unknown VLAN purpose, non-campus wide networks, DHCP scope exhaustion, difficult to scale, spanning-tree broadcast storms, inconsistent quality of service, parent to child client application disturbances

Goal: Create segmented VLANs for each end device category. Separating each VLAN's traffic to obtain an organized network environment.

Result: An improved network environment achieved by segmenting end devices across campus switches. Resulting in better quality of service and scalable ecosystem.

Discovery

Finding every network connected device on campus and documenting the switch, switch port, and purpose

Create

Created new VLANs across 15+ switches that participate in MST OSPF. Each VLAN has a corresponding DHCP scope

Testing

Isolating a low impact device on each VLAN to test the new network scope and configurations prior to campus wide migration

Migration

Reconfigured every device off of the old production VLANs and onto the new segmented VLANS

Audit

Surveying what devices are left to migrate over, problem devices, static devices, servers, groups of devices that will be uplifted rather than moved due to high availability impact

Alignment

Completing the migration and audit items. Uplifting networks, moving static devices, physically finding the handful of lost and unknown devices, stripping the network of old VLANs and DHCP scopes that are not in production
