Roundtable Discussion – Campus Network Design

How to build a Campus Network

How many devices will be on the network ?

What kind of Devices do you need ?

• Switches , Core (maybe distribution) Access
• L3 Routing , classic Routers, L3 Switches, Firewalls
• WLAN Access Points, Controller
• Wan Optimizer
• Infrastructure for VoIP
• What tools are you using?

How to build a redundant campus network:

Layer 2

• Spanning tree, Multi Chassis Link Aggregation , LAG/LACP
• Stacking, like Cisco Cat 3k line, VSS technology  or Avaya Switches, Juniper virtual Chassis , HP IRF
• virtual Switch Clustering , Cisco vPC, Avaya SMLT, Cisco VSS

Layer 3

First Hop redundancy Problem:

• VRRP
• HSRP
• RSMLT

Choose the right technology for your needs / usecase.

Protect your Network:

• Loop prevention   STP, BPDU Guard
• DHCP Snooping
• Rate Limiting
• Access control

Use a seperate management network for your network devices.

Use encryption for management such as SSH, SNMPv3 and HTTPS

Preconfig / Templates / Provisioning:

• Switches
• Ports
• VLANs

Out of Band Management

• Opengear
• Cradlepoint

What tools are you using?

I recently needed a small compact remote jumpbox that i could use to help isolate a problem I was experiencing in a physically remote network. I employed a Raspberry Pi 2 Model B with Anker USB 3.0 to RJ45 Gigabit Ethernet Adapter which allowed me to use the small computer as both a jumpbox and a remote packet capture solution. I was able to manage the computer remotely over the built-in Ethernet adapter and then used the Anker (it’s actually a Realtek chipset) Ethernet adapter to capture the problem frames coming from a SPAN port using tcpdump with some capture filters. You’ll need to be careful of how much traffic you throw at the little computer but I was really impressed with how well the solution worked.
