Today we’re going to play with bridging!!! Why are we talking about bridging in 2016 you ask? Well because I’m going to making a few posts as I work my way through the CCNP Cloud certification as well as catching myself up on the new CCIE DC blueprint so I’ll be talking a lot about VXLANs for a least a couple posts. Since bridging is making a come back in L2VPNs and such I figured why not start here? Also I just want to write about something that doesn’t need 50 screenshots 🙂

Checkpoint – The Gentle SIC Reset
StandardI found myself in a awkward situation the other weekend where I lost access to Check Point’s internal networks after switching over some networks due to anti-spoofing and after a short adventure of spinning up a new management server in Azure, pointing the firewall to it and pushing a more permissive rule I was back online!!!!

Phoning it in – Bashing UCOS
StandardWhen my UC lab blew up I contacted Cisco to get all the licenses reset which they promptly did, but to my absolute horror I found out I gave them the wrong mac address for my UCCX VM!!!!!!!!!!!! Since sending a email to the friendly TAC lady is far to much work and frankly a boring blog topic, let’s instead enable the bash shell in my UCCX and change the mac address to be what I sent them 🙂
Phoning it in – Deploying CUCM
StandardI was planning on finishing the CUCME topics before diving into CUCM but as luck would have it one of my ESX servers blew up so I had to reinstall my CUCM lab and as they say “when life gives you lemons, make a blog post about it.” So today we’ll look at how to install UCOS based servers (CUCM, CUC, CER etc) since the installs are so similar I will just show the publisher and subscriber install for CUCM, then we’ll look adding the servers to Prime Licensing, and we’ll close out with how to do a upgrade!
