CYA! Cover Your Assets (By Securing Them) (Thwack)

Still using local accounts for device access? Don’t know what a Term Process is? You need to CYA!

On the Solarwinds Thwack Geek Speak blog I looked at a variety of security (and related) features which should be configured on all devices. Please do take a trip to Thwack and check out my post, “CYA! Cover Your Assets (By Securing Them)“.

Please see my Disclosures page for more information about my role as a Solarwinds Ambassador.

REVIEW: Users assess network virtualization software from VMware and Micro Focus

Network virtualization is a process of abstraction that separates the network from its underlying physical hardware, allowing for the customization of network infrastructures through aggregation and provisioning measures. Among the potential benefits of network virtualization are faster provisioning of networks, easier management of networks, and more efficient use of resources.To read this article in full or to leave a comment, please click here(Insider Story)

What is convergence in different field of networking ?

What is convergence ?   This term has different meaning for different networking groups. In this post, I will explain the two most common usage. This kind of knowledge definitely will differentiate you from the others ?   If you are a layer 3 person, I mean if you are familiar with routing, most probably […]

Big Data Storage: 7 Key Factors

Beyond the Firewall

Few IT departments engage in future planning

It’s an old cliché: If you fail to plan, you better plan to fail. That seems to apply to a new study by CompTIA that finds only 34 percent of businesses surveyed plan their IT infrastructure beyond one year.The reasons are legitimate: the disruption brought about by the migration to cloud computing and Internet of Things (IoT) deployments. Both are seriously disruptive and can make long-term planning a challenge. To stay flexible to changes as they undergo a digital transformation, businesses are reticent to plan beyond one year out. + Also on Network World: Cost optimization gains ground in IT infrastructure decisions + The report, titled "Planning a Modern IT Architecture," also found some of the usual problems dogging IT shops. Four in 10 companies said they lacked the budget for heavy investment in new architecture, and one-third said they don’t have the knowledge on emerging technologies and new trends to formulate an integration plan. To read this article in full or to leave a comment, please click here

Enterprise Network on GNS3 – Part 2 – Access Layer

This is the second from the series of the articles that discuss a complete configuration of the enterprise network. Our enterprise campus network consists of the core, distribution and access layer. This network infrastructure design is called a three-tier network model. Each layer has specific function. The access layer provides access for end users to the network . They are two access switches located inside the access layer. The access switches OpenSwitch-Acc-I and OpenSwitch-Acc-II are OpenSwitch Qemu appliances installed on VMware VMDK disks. The switches run OpenSwitch network OS version 0.4.0 and they have assigned 1024 MB memory by GNS3. More details about building OpenSwitch appliance prior to version 2.0 can be found here.

The ports Ethernet 3 a and 4 on both switches are configured as access ports and they connect PC1 and PC4 to the campus network. The ports Ethernet 1 and Ethernet 2 are uplinks that connect access switches to the distribution switches. They are configured as trunk ports, carrying traffic from multiple VLANs. Thanks to redundant uplink connection, the access switches remain connected to the upper layer, even in case of the failure one of the distribution switches.

Why Cisco Catalyst 9K is so special ?

Well today I am going to talk about the new Switches which Cisco introduces in July 2017. These are very much powerful switches and going to replace Cisco 3850 and Cisco 4500 Switches with more innovation and high qualities.

I already wrote two articles on Cisco catalyst 9K series switches and articles are below

Cisco Catalyst 9300 Switch
Cisco Catalyst 9400 Switch

Now the question is Why Cisco Catalyst 9K is so special ?
Cisco Catalyst 9K is a next Generation platform switches introduces to support DNA infrastructure which Cisco just came up this year. Cisco comes up with the innovation and below are the support features set up in Cisco Catalyst 9K Switches.

• IOT devices convergence : CoAP / IoT Device profiling, Perpetual PoE, IEEE 1588 / AVB and Emerging Standards: MUD
• Mobility Device Features : Fabric Enabled Wireless, Embedded WLC, Distributed Wireless Scale, Unified Control & Policy with Wired & Wireless Guest
• Security : Encrypted Traffic Analytics; 256bit MacSec / IPSec; Trustworthy Systems; Group based policy; Full Netflow for StealthWatch
• Open to Cloud: DevOps Toolkit; Netconf/Yang Models; Streaming telemetry; Patching/GIR and Application Hosting.
• IOS Features : Open IOS-XE with UDAP 2.0 features best in industry.

Go Hack Nights at Cloudflare

At Cloudflare we're extensively using the Go programming language to build a better Internet. Go is a free and open source programming language created by Google in 2007 and open sourced in 2009. Earlier this year, Go made news when it entered the list of top 10 programming languages on the TIOBE Index.

Recently we launched an internal monthly Go Hack Night at our San Francisco office, open to anyone who works at Cloudflare regardless of their department or position. Anyone from newbie programmers to our most experienced Go engineers are encouraged to attend, and experienced engineers are asked to throw on a mentor badge and help guide colleagues with installing and learning Go.

We had over 30 attendees at our inaugural Go Hack Night, and our survey reveals some great stats:

• 26% of attendees were completely new to programming
• 61% of attendees were experienced in other languages but new to Go
• Every attendee said they learned something!

We actively encourage an inclusive learning culture and we're super excited to make the Go programming language more accessible to our entire company.

If you're interested in working with Go and helping to build a better Internet, we're hiring!

P.S. if Continue reading

Cisco POE, POE+ and UPOE introduction

Today I am going to talk about Cisco UPOE. Before we are going to discuss about the Cisco UPOE we will run through POE and POE+

Cisco POE : Cisco POE means Power over Ethernet by which you can provide the power to the endpoint in the LAN infrastructure. So now question is where and why we required POE in the LAN infrastructure. Well sometimes we have the infrastructure where we have some power issues or cabling issues while extending the power to the IP phones. The best to provide the power via LAN network POE switch.

Fig 1.1- Basic POE Switch connected with IP Cameras

IP telephones need power for operation, and Power over Ethernet supports scalable, manageable power delivery and simplifies IP telephony deployments. As wireless networking emerged, Power over Ethernet began powering wireless devices in locations where local power access did not exist.

As per the Cisco offers a comprehensive range of 802.3af-based Power over Ethernet support across the Cisco Catalyst Intelligent Switching portfolio which includes both 10/100/1000 and 10/100 PoE LAN connections, including a 96-port 10/100 PoE module for the Cisco Catalyst 6500 Switch.
