UTS1 1

Summary

The video script discusses the University of Technology Sydney (UTS) network, focusing on both wired and wireless aspects. The speaker outlines customer expectations, including network reliability and regular patch management for switches, wireless controllers, and network management systems (NMS). They mention the use of ClearPass for authentication and the ongoing replacement of older switches with newer models as part of the AXIS layer project. The speaker also covers the support provided by DXE, including managing and maintaining software patches, handling RMA for faulty switches, and offering design input for network changes. The discussion includes the use of various NMS tools and the network's hierarchical structure, from access to core layers, with an emphasis on the transition to new technologies and the management of these systems.

Takeaways

• 📝 The document discusses the UTS network, covering both wired and wireless aspects, with a focus on DXE's contract responsibilities for support.
• 📞 Telephones are managed by on-site UTS staff, and not part of the support contract, although they do connect to DXE's switches.
• 🔄 Patch management is a key responsibility, including for switches, wireless controllers, and Network Management System (NMS) appliances.
• 🛠 Regular RMA (Return Merchandise Authorization) is performed for faulty switches, although it's a rare occurrence.
• 🔧 DXE also provides design input for network changes and works on projects as they arise.
• 🔐 ClearPass is a significant technology used for authentication, primarily for wireless and guest access, and also for switch logins.
• 📡 The wireless network is managed by a Mobility Master virtual appliance and physical controllers, with various AP models in use across the campus.
• 🏢 The campus network infrastructure includes access, distribution, and core layers, with specific models of switches used at each layer.
• 📈 The network is monitored and maintained using tools like OmniVista for wired and wireless, and PRTG for additional monitoring needs.
• 🔄 There's an ongoing project to replace older switch models with newer ones, such as replacing 6850s with 6860s in the access layer.
• 🗂️ The speaker mentions the need to update diagrams and documentation to reflect recent changes in the network infrastructure.

Q & A

What is the primary responsibility of DXE in terms of UTS network support?

DXE is mainly responsible for providing support for the wired and wireless network from a contract perspective, excluding telephone services.

What are the two products used for Network Management Systems (NMS) at UTS?

The two products used for NMS are OmniST 2500, which is for wired switches, and OmniST 3600, which is for wireless controllers and access points.

What is the significance of the patch management cycle in UTS network support?

The patch management cycle is crucial for maintaining the operational integrity of switches, wireless controllers, and NMS appliances, ensuring they are regularly updated for security and functionality.

How does DXE handle the replacement of faulty switches under contract?

If a switch dies and is under contract, DXE can easily perform an RMA (Return Merchandise Authorization) to replace the switch.

What role does DXE play in network projects and design input at UTS?

DXE is involved in providing design input for any network changes that the customer might want in the future, working on projects as they arise.

Why was ClearPass implemented at UTS, and what does it support?

ClearPass was implemented to replace the in-house radio server and is now used for wireless and guest authentication, as well as switch logins.

What is the Mobility Master, and what is its function in the UTS network?

The Mobility Master is a virtual appliance running in the data center, mainly for control purposes, used for configuration management and controlling the physical appliances and access points.

What are the different switch models that DXE supports at UTS, and are there any models being phased out?

DXE supports various switch models including 6850, E switches, 9700, 6855, 6450, 6465, 6860, and 6900. The 6850 and E switches are being replaced as part of the AXIS layer project.

How does the core layer of the UTS network differ from the access and distribution layers?

The core layer, previously using 10K switches, has been updated with newer models that are smaller in form factor and offer more port options, including 10 gig and 40 gig capabilities.

What is the role of the 4650 controller model in the UTS wireless network?

The 4650 controller model is used across the UTS campus in main buildings to manage and control the wireless access points.

How does the OmniVista 3600 differ from OmniVista 2500, and what is its relationship with Aruba's Ave Manager?

OmniVista 3600 is an Aruba product rebranded by Alcatel-Lucent as OmniVista, while OmniVista 2500 is an Alcatel product. Aruba's Ave Manager is essentially the same as OmniVista 3600 but under its original branding.
