As previous blogs have indicated I have my hands on a Juniper Networks EX-2200. This device has great functionality what I found great was the dual-purpose uplink ports. As pictured below these ports are linked and can take either a RJ-45…
LLDP is the non proprietary version of CDP. This discovery protocol has applications that can make an administrators life much easier. Now with two physical devices I am going to implement LLDP on JUNOS with the EX-2200 and SRX110. First…
The Nexus series of data center switches by Cisco allow for an extended fabric configuration. By utilising the notion of remote line cards, an engineer can deploy Nexus 2200 series switches as Top of Rack. These top of rack switches…
Today was a good day. I had a new arrival into the family. The Juniper Networks EX-2200 12-C PoE+. In addition to my SRX110-H-VA Firewall I now have a fully fledged JUNOS switch with all the bells a whistles. Juniper…
In the previous post we discussed what the VMware vSwitch actually was. This allowed the reader to gain insight into the difference of a software switch compared to a hardware switch. This discussion assumes a default vSwitch install and the…
Virtual networking isn’t a new thing. It has been around for a while and we get better at it as the months pass us by. Who hasn’t heard of SDN? Well before I buy into that realm and blog about…
Again we come to the topic of guarding the edge. Another day, another battle. Last time it was Spanning-tree defence mechanisms, today it is mac address spoofing. Every device has a MAC address and is populated into a devices CAM…
As many of you are well aware I own a Juniper Networks SRX110H-VA firewall. THis firewall has been the focus of many blogs up until now. I have covered off a myriad of subjects with many more to come in…
Today I sat the JNCIS-ENT exam. As my previous post let on, I didn’t pass the exam the first time. I was close but not close enough. I felt it was a fair exam and I am going break it…
Just a quick one today. I had planned to take the JNCIS-Security this month but accidentally booked JNCIS-Enterprise. Not to worry in the slightest. The same great content will be served up, just with a focus on routing and switching.…
For many engineers, Spirent equipment is the stuff of legends. The packet generators and network test environments were expensive enough to come with a human to drive them. Deployments in the tens to hundreds of thousands of dollars were not uncommon and rarely seen…
Today I passed the Juniper Networks JNCIA JUNOS exam. I am quite elated to be honest. My roots as a network engineer have come from the Cisco Network academy and I have climbed part of their certification tree. Upon acquisition…
I discussed in my previous post that I wanted to add virtual routing instances to the SRX. This would allow me to learn OSPF in a real device see how it handles on JUNOS. Kurt Bales (@networkjanitor) dropped some hints…
Currently I am getting a big dose of the Juniper sauce. I like it thus far. The device that has been getting my whistle wet is the SRX110. This bad boy was plonked between my desktop and current network. I…
Disruption and change. Something that makes managers sphincters twitch and 9-5 IT staff groan that more work is coming. You know what? Deal with it. Why am I being a cocky and high-horse like? Well, I’ve had a dose of…
I have been using the Nexus platform for a year now. I always find I get “ah-ha” moments due to the fact most of the time I am hiding in IOS. Here is a little one regarding showing interfaces. I…
Currently Greg Ferro is duking it out with Cloud toad about MPLS. Is it dead? Will Ivan’s books be put to bed for ever? Find out. I will live blog this event – first attempt at this sort of thing.…
It was over a game of pool with John Harrington that I met Doug Hanks. I knew very little of the man other than he was “the man” at Juniper to speak to regarding MX-anything. It was very shortly after we…
Disclaimer about #NFD4 posts Automation. The benefits I find of automation is that workflows that are in place can be taken and performed on demand without manpower or assets assigned at every stage. Over at Juniper it seems that automation is a big focus…
It is the morning after the week before. I have taken my first step into a larger world by the awesomeness that is Gestalt IT’s Network Field Day 4. I am the last delegate remaining at the SJC Doubletree Hilton…
If you are in IT and not a 9-to-5’er you have most definitely exposed to the ever evolving nature of technology. SDN this, Virtualize that, and to the cloud with the rest. Keeping up with technology that vendors develop without the marketing…
Certification requires a lot of lab time. I mean a lot. Hundreds of hours of thorough, insightful, and meaningful labbing. Let alone the time invested behind the CLI of a CCIE certification. There are two routes these days that most…
Once again the VLAN topic comes to the forefront but immediately I know this will apply to all aspects of the blueprint. The old adage goes something like “There are many ways to skin a cat”. Lets take the example of creating…
Now VLANs may seem simple but you need to understand every facet when working towards the CCIE. The VLAN database can only store 1-1005 VLAN within it due to it only seeing 10 bits within the VLAN ID field. This…
Today is a significant day. After much tossing and turning and discussions with my wife I have finally decided to start down the path of the CCIE Study. Those who follow my blog may know that I am not yet…
