Private VLANs w/ VMware vDS and Cisco Nexus 5000: A Configuration Reference

When configuring the networks of a virtualized environment, private VLANs expand the functionality of a standard VLAN.  This article describes the configuration of PVLANs from both the VMware and Cisco perspectives.  The purpose of this article is to provide a brief configuration overview.  It’s likely you already know what PVLANs are and how they work, so I won’t go into much detail there.  For more information about VLANs and PVLANs, check out Cisco’s Securing Networks with Private VLANs and VLAN Access Control Lists. Usage Scenarios DMZ security – Servers running in a DMZ can be isolated from one another. Should a DMZ guest be compromised, the guest is unable to communicate with any other guest in the the DMZ (given each are a part of an isolated PVLAN) Hosted cloud infrastructure – A customer environment (consisting of multiple guests) in a community PVLAN are able to communicate amongst themselves, but cannot communicate with a different community PVLAN Overcome standard VLAN limitations – While PVLANs exist with their own set of limitations, private VLANs greatly extend the functionality and usefulness of a standard VLAN Configuration Overview vlan 2410 int: 192.168.7.1 (primary 2410, secondary 2411) vlan 2412 int: 192.168.8.1 (primary 2412, secondary 2413) vlan 2411 – isolated vlan 2413 – community bperove-vm1: 192.168.7.10 – dvPortGroup1 – primary 2410, secondary 2411 bperove-vm2: 192.168.7.11 – dvPortGroup1 – primary 2410, secondary 2411 bperove-vm3: 192.168.8.10 – dvPortGroup2 – primary 2412, secondary 2413 bperove-vm4: 192.168.8.11 – dvPortGroup2 – primary 2412, secondary 2413 bperove-vm5: 192.168.8.12 – dvPortGroup2 – primary 2412, secondary 2413 bperove-vm6: 192.168.8.13 – dvPortGroup3 – primary 2412, secondary 2412 Configuration of VMware vDS (DVS) dvSwitch...

Installing a WLAN @ Ameristar Casino, Black Hawk, Colorado

What’s it like to install a wireless network in a casino?  With the help of two others, we lit up ~200 APs at the Ameristar in Black Hawk just a few weeks before the grand opening on 9/29.  This was a ton of work, but it was worth it.  Here are some photos that I snapped.
