Overview 

StrongVPN is one of the oldest in the industry, beginning as a humble PC company in 1994. A subsidiary of Reliable Hosting, the company was created after a move to San Francisco prompted the sale of VPN services.

The US-based company doesn’t promise a whole lot on its website, but under the hood it’s a fast VPN with a no-log policy and great customer service. It supports 5 concurrent connections for $10 per month, or just $5.83 a month if you opt for a yearly package.

While some of the best VPNs focus on a wide range of servers, StrongVPN prioritises speed and the ability to unblock Netflix. It has servers in 45 cities across 23 countries, most of which can bypass region blocks.

Such functionality has made this StrongVPN very popular in China and other countries with aggressive blocking policies. This review will analyze the benefits for a new, global audience.

Ease of Use – StrongVPNGUI Interface

StrongVPN’s install is as simple as it gets. Users are presented with a regular installer and just have to hit next until it’s complete. StrongVPN intelligently installs TAP drivers, requiring no extra prompts. After completion, the application will launch automatically.

At first glance, StrongVPN’s interface is simple. It presents your location, a list of servers, and VPN protocol used to encrypt traffic. Most users will never have to go outside of this interface, leaving a minimal, simple experience.

Complete Guide to Nexus Checkpoint & Rollback Feature. Fast Recovery from Nexus Misconfiguration. Nexus 9000, 7000, 5000, 3000 - 5.0 out of 5 based on 13 votes

cisco nexus configuration checkpoint rollbackThe Cisco NX-OS checkpoint feature provides the capability to capture at any time a snapshot (backup) of the Cisco Nexus configuration before making any changes. The captured configuration (checkpoint) can then be used to roll back and restore the original configuration.

The NX-OS checkpoint and rollback feature is extremely useful, and a life saver in some cases, when a new configuration change to a production system has caused unwanted effects or was incorrectly made/planned and we need to immediately return to an original/stable configuration.

With Catalyst IOS switches we would manually remove or restore IOS commands but with the Nexus NS-OS checkpoint-rollback feature this is a much faster and safer process that can be executed even by an authorized user with basic experience/knowledge on Nexus switches.

Let’s take a quick look at the topics covered in our article:

Finally, we must point out that basic knowledge of the Cisco NX-OS is required for this article.

Readers can also refer to our Introduction to Nexus Family – Nexus OS vs Catalyst IOS for more information on Nexus switches. 

NX-OS Checkpoint & Rollback Limitations - Guidelines

The Checkpoint and Rollback feature has the following main configuration guidelines and limitations:

  • The maximum number of checkpoints supported is equal to ten (10).
  • Checkpoints are stored in an internal repository not accessible by the common user.
  • Checkpoints are persistent and synced between redundant supervisors.
  • It is not possible to apply or import the checkpoint file from another Nexus switch. Checkpoints can only be used on the device they were created on.
  • Only one user at a time can perform a checkpoint, rollback, or copy of the running configuration to the startup configuration.
  • Checkpoints are cleared from the system’s database after executing the write erase or reload command (switch reload).
  • Checkpoints can be manually cleared by running the clear checkpoint database command. The checkpoints saved to the bootflash are not affected by the aforementioned commands.
  • Checkpoints are only local to the NX-OS switch.
  • Rollback using files stored in bootflash is supported only if it has been created using the checkpoint command.
  • Checkpoint names must be unique. You cannot overwrite previously saved checkpoints. If attempting to overwrite existing checkpoints the user will receive the following error: ERROR: ascii-cfg: Checkpoint Name already exists (err id 0x405F002B)
  • Checkpoints are local to a virtual device context (VDC) for the Nexus 7000.
  • Rollback is not supported in the storage VDC for the Nexus 7000
  • Rollback is not supported on the Nexus 5000 after enabling the FCoE feature. System will generate the following error after enabling the FCoE feature: ERROR: FCOE is enabled. Disabling rollback module.

Understanding and Configuring the NX-OS Checkpoint Feature

Working with the Nexus Checkpoint feature is a very easy process and the commands used follow a logical order allowing the easy usage of this fantastic feature.

Introduction to Cisco Nexus Switches – Nexus Product Family. Differences Between Nexus NX-OS & Catalyst IOS. Comparing High-End Nexus & Catalyst Switches - 4.9 out of 5 based on 27 votes

Introduction to Cisco Nexus Data Center SwitchesThis article introduces the Cisco Nexus product family (Nexus 9000, Nexus 7000, Nexus 5000, Nexus 3000, Nexus 2000, Nexus 1000V and MDS 9000). We explain the differences between Nexus and Catalyst switches but also compare commands, naming conventions, hardware capabilities etc. between Nexus NX-OS and Catalyst IOS operating systems. To provide a comprehensive overview we explain where each Nexus model is best positioned in the Data Center and directly compare high-end Nexus switches (Nexus 9000/7000) with high-end Catalyst switches (Catalyst 6800 / 6500) examining specifications, bandwidth – capacity, modules and features (High-Availability, Port Scalability, VDC, vPC – VSS, OTV, VXLAN, etc).

For our readers convenience we have made available for free download over 90 different datasheets in our Cisco Data Center download section.

Following are the topics covered in this article:

Cisco Nexus Product Family

The Cisco Nexus Family of products has become extremely popular in small and large data centers thanks to their capability for unifying storage, data and networking services. Thanks to the Cisco Fabric Interconnect they are able not only to support all these services but also provide a rock-solid programmable platform that fully supports any virtualized environment.  The Cisco Nexus family includes a generous number of different Nexus models to meet the demands of any Data Center environment. Let’s take a look at what the Nexus Family has to offer!

The Nexus Product Family

The Nexus Product Family

Cisco Nexus 9000 Series Switches

These data center switches can operate in Cisco NX-OS Software or Application Centric Infrastructure (ACI) modes. The main features of the new Cisco Nexus 9000 Series are: support of Fabric Extender Technology (FEX), virtual Port Channel (vPC), and Virtual Extensible LAN (VXLAN). There are a few key differences between the Cisco Nexus 7000 Series and Nexus 9000 DC switches. The Nexus 9000 supports Application Centric Infrastructure (ACI) in contrast to the Nexus 7000 switches.  However, the Cisco Nexus 9000 switches do not support the VDCs (Virtual Device Context) technology like the Nexus 7000 and the Nexus 9000 Series doesn't support storage protocols, in contrast to the Nexus 7000. Finally, it is foreseen that the Nexus 9000 will complement the Nexus 7000 as data centers transition to ACI.

The Nexus 9000 Series Data Center Switches

The Nexus 9000 Series Data Center Switches

The Nexus 9000 switches are available in a variety of models and configurations starting from the Nexus 9200 series (1 RU) Cloud Scale - standalone, Nexus 9300 series (1RU), Nexus 9300-EX (1RU) Cloud Scale standalone/ACI, Nexus 9500-EX (1RU) Cloud Scale Modules to the Nexus 9500 Cloud Scale switches (4, 8, 16 slots).

Cisco Nexus 7000 Series Switches

They can provide an end-to-end data center architecture on a single platform, including data center core, aggregation, and access layer. The N7k series provides high-density 10, 40, and 100 Gigabit Ethernetinterfaces. The main features of the Cisco Nexus 7000 Series are: support for FEX, virtual Port Channel (vPC), VDC, MPLS and Fabricpath. In addition, the N7K supports fairly robust and established technologies for multi-DC interconnect (DCI) such as OTV and LISP.  The N9K does not support these well-established DCI technologies, but a newer DCI technology, VXLAN, BGP, EVPN, that can be deployed for site-to-site DCI.

The Nexus 7000 Series Data Center Switches

The Nexus 7000 Series Data Center Switches

The Nexus 7000 series consists of the 7000 and 7700 series switches, the latter being an updated series to the original 7000 series. The Nexus 7700 series offers higher bandwidth per slot (1.3Tbps compared to 550Gbps), greater performance and ability to support up to an impressive 192 100GE ports (7700 – 18 slot) compared to 96 100GE ports (7000 – 18 slot).
