Black-and-white portrait of Jay Stants, the left side of his face dissolving into soft blue light

Network Architect & NetDevOps Engineer

Jay Stants

I build the networks a global enterprise runs on: campus, WAN, wireless, and identity, from design through cutover.

20 years in enterprise networking. I designed the Cisco ISE platform behind 60,000+ endpoints and led the move of about 900 access points from Meraki to Catalyst 9800, site by site.

About

I design and run the enterprise networks thousands of people rely on to do their jobs: campus switching, global WAN, wireless, and identity.

When my work goes well, users don't have to think about the network, which is the point.

Every network change I run follows the same four steps:

  1. Audit first

    The monitor-first rollout that grew into 60K+ endpoints behind 802.1X.

    How I moved 45,000 endpoints
  2. Pre-stage everything

    A 1,500+ device TACACS estate and 190 WLANs, repointed onto a parallel-built ISE 3.x.

    Global AAA migration
  3. Cut over quietly

    About 900 access points moved from Meraki to Catalyst 9800, site by site.

  4. Leave automation behind

    Python tools and Ansible playbooks engineers can run without touching git.

    We retired VSS. The redundancy model stayed.

    Retiring an end-of-life VSS core meant new hardware and a new virtual-chassis technology. The BGP redundancy model built on top of it didn't have to change.

    Building network automation that outlives its author

    A platform where engineers run automation as a shell command, not a git workflow, NetBox stays the single source of truth, and no secrets touch the repo.

    The migration workbook: how I make risky network changes boring

    About 900 Meraki access points migrated to sixteen Catalyst 9800 controllers (now roughly 1,000 after density-driven additions), 190 WLANs across four regional datacenters, and a quiet AAA migration to a parallel-built ISE 3.x environment. The method: audit first, pre-stage everything, cut over with the radios.
