A place to hang out and share. In short, Breezy!

Updated Network Layout

I now have 2 sites connected across an IPsec VPN over the Internet. One is my office (on the right) and the other is a rental property (on the left) where my main data centre is located.

A cleaner look at my Network Layout

This is my latest network layout. I now have port channels using the Etherchannel protocol between my physical 3560 "core" switch and a Nexus 1000V switch in each of my 2 ESXi hosts. One of my ESX hosts, ESX2, I use for testing purposes and the other ESX host, ESX1, is more or less used for my production network. I have my BES (BlackBerry Enterprise Servers), Active Directory, Exchange, DNS and web servers (ie: this site!) on ESX1. I have other devices not pictured taken from the virtual product portfolio of Cisco's....devices like ASA1000V, VSG, virtual email security appliance (ESAv) and virtual web security appliance (WSAv). My main firewalls are currently Cisco ASAv (virtual ASAs) configured Active/Standby between the two ESXi hosts.

Lots of fun!

Automatically Reboot DSL modem Daily

I was faced with the problem that when my tenants aren't in our townhouse I have no one to reboot the DSL modem when it loses sync. Why is this a problem? It's because my "data centre" is there. Email servers, this web server, etc., are all hosted there. My DSL provider regularly runs into uptime issues (don't they all?) so I needed a way to automatically reboot the modem every day in the wee hours of the morning. So what to do?

Network Layout

Here is my Layer 1-2 network layout. All links are 802.1Q trunks unless otherwise noted.

Also: GC=Game Controller; AP=Access Point; SB=Slingbox, C160=Cisco Ironport C160, WLC=Wireless LAN Controller, TS=Terminal Server

This site's sister site, www.ipv6net.ca, uses a tunnel broker for IPv6 connectivity -- here's how....

You can run a 6to4 tunnel (like the ones www.he.net offer for free) through an IPv4 router. It simply tunnels IPv6 packets inside an IPv4<-->IPv4 tunnel.

[IPv6 LAN Subnet]<--->[IPv6/IPv4 router]<---IPv4 Internet---->[IPv4/IPv6 tunnel broker peer]<--IPv6 Internet-->

Site is Up! Now What?

I hope to start adding in forums and the like in the next little while. For now, I have a couple of Cisco forums and some general forums to start the ball rolling.

Caveats for Cisco Virtual Wireless LAN Controller (Virtual WLC)

This is quite interesting. I had a heck of a time trying to install/configure a Cisco Virtual Wireless LAN Controller and just came on this post:


To make a long story short, the Cisco installation instructions work fine, but there are some important caveats that the blogger found:

Points To Keep In Mind on the vWLC:

- Cisco Access Point not on code 7.3 and above would not join vWLC
- Incorrect time configure initially caused the self-signed certificate (SSC) on the vWLC to be invalid


Welcome to Breezy!

If you've been regularly dropping in to this site, you might have noticed that all the content has disappeared. That's right....ker-blam! I had a little, shall we say, "experiment" with upgrading my Hypervisor to ESXi 5.1 and it blew away my whole RAID 1 array. Oops!

Anyway, time for something fresh.
