Juniper Filter-based VLANs

So during my efforts to study for the Juniper JNCIP-Ent ( Enterprise Routing & Switching ) exam, I happened to come across a Juniper switching feature called Filter-based VLANs.

In normal VLAN-based switching, a device’s assigned VLAN is configured on it’s access port and can’t be changed no matter what is connected to that port.

A Quick Look at AlienVault USM Anywhere

The company I’m working for is ramping up capability to support AlienVault USM Anywhere. Here’s a few notes from what I’ve learned about the product.

Welcome to the new site, better than the old site

Welcome to my new web site.

I’ve done a fair bit of work to rebuild my web site from the old manually edited HTML site that was too difficult to maintain. I’ve create this new site as a hosted WordPress site which will allow much easier posting of regular blog entries, and much better formatting.

Enjoy!
