Network Refresh and Cisco ISE Implementation

Customer Need

  1. The client had an outdated network infrastructure consisting of End-of-Life hardware from a multitude of vendors
  2. Using a multi-vendor approach caused spanning tree protocol (STP) issues resulting in network outages
  3. Existing wireless infrastructure was outdated, and access points had to be individually managed
  4. The client didn’t have a guest network, and there was no way for the IT staff to control employees connecting their own devices on the network
  5. The three-layer network design was comprised of core, distribution and access layer. It was configured in such a way that in the event of a floor distribution switch failure there would be a complete wired and wireless network outage for that floor

 

Solution

  1. Designing a two-tier network topology with core and access layers
  2. Switching to a single vendor approach by implementing Cisco Catalyst series switches in the core and access layers
  3. Implementing a Cisco Wireless Controller for access point management
  4. Implementing Cisco ISE for wired and wireless access

 

s4nets worked with a software company to redesign their Pittsburgh office’s network, implement wireless and guest access, and enhance their security by implementing a network access control (NAC) solution.

 

Impact

  1. Two-tier network topology resulted in a more resilient network design
  2. Single vendor approach eliminated spanning tree protocol (STP) issues that used to cause network outages
  3. Cisco Wireless Controller allowed for access points to be centrally managed
  4. Cisco ISE allowed the client to create and implement guest and BYOD access policy
