Juniper Ex2200 Software Upgrade Usb

To get the optimal network performance, and to fix a vulnerability, you can upgrade the firmware on your device. I recently bought a Juniper SSG-20 for my homelab to learn some more complex networking and the first thing I tried to do was update the firmware. Unfortunately, I can't seem to do this through the web UI as it says it's failed. I'm wondering if I need to upgrade to a specific version first, and then upgrade to the next until I'm fully up to date?

Juniper EX2200 can't boot. I recently acquired a Juniper EX2200-24T-4G switch, but I have some issues getting it up and running. When I power on the switch the boot process looks normal, but after some time it suddenly turns up with some errors and after that it automatically reboots. I have tried to reinstall Junos through the loader prompt.
It's been about a day and Juniper has yet to confirm or deny my request to make an account. The short question is: how can I download firmware without a support contract? I just would like to download latest ex2200 firmware 12.3R12. If it's not possible, I would be grateful if someone helped facilitate my download.

Sorry, this product is no longer available, replaced by the EX2300-24P.

Product Overview

The Juniper Networks EX2200 line of Ethernet switches offers a compact, high-performance solution for supporting today’s converged network access deployments.

Each EX2200 switch includes an application-specific integrated circuit (ASIC)-based Packet Forwarding Engine (PFE) with an integrated CPU to consistently deliver wire-rate forwarding, even with all control plane features enabled. Based on existing, field proven Juniper Networks technology, the PFE brings the same level of carrier-class performance and reliability to the EX2200 switches that Juniper Networks routers bring to the world’s largest service provider networks.

Architecture and Key Components:

The EX2200 occupies a single rack unit, delivering a compact solution for crowded wiring closets and access locations where space and power are at a premium. The EX2200 switch’s 10-inch depth and low acoustics also make it ideal for open office deployments.

Each EX2200 switch supports four fixed front panel GbE uplink ports with pluggable optics (purchased separately) for high-speed backbone or link aggregation connections between wiring closets and upstream aggregation switches. The EX2200 also features a front panel mode button that offers a simple interface for bringing devices up and selecting LED modes.

A dedicated rear panel RJ-45 Ethernet port is available for out-of- band management, while a rear panel USB port can be used to easily upload the Junos operating system and configuration files.

The EX2200 line provides a high-performance solution for converged networks in branch offices as well as campus wiring closets.

Virtual Chassis Technology:

The EX2200 supports Juniper’s unique Virtual Chassis technology, enabling up to four interconnected EX2200 switches to be managed as a single logical device, delivering a scalable, pay-as- you-grow solution for expanding network environments.

While EX2200 switches can be interconnected over any of the front-panel uplink ports, the last two ports are configured by default as Virtual Chassis ports, automating deployments when using standard GbE SFP transceivers (sold separately). These two ports can also be configured as GbE uplinks to aggregation devices by disabling the Virtual Chassis technology.

When deployed in a Virtual Chassis configuration, the EX2200 switches elect a master and a backup switch based on a set of preconfigured policies or criteria. The master switch automatically creates and updates the switching and optional routing tables on all other Virtual Chassis switch members. Switches can be added to or removed from the Virtual Chassis configuration without service disruption.

EX2200 Virtual Chassis configurations operate as highly resilient unified systems, providing simplified management using a single IP address, single telnet session, single command-line interface (CLI), automatic version checking, and automatic configuration. The EX2200 switches are also capable of local switching, so packets coming into a port destined for another port on the same switch do not have to traverse the Virtual Chassis, increasing forwarding capacities.

EX2200 Virtual Chassis configurations implement the same slot/ module/port numbering schema as other Juniper Networks chassis- based products, providing true chassis-like operations. By using

a consistent operating system and a single configuration file, all switches in a Virtual Chassis configuration are treated as a single device, simplifying overall system maintenance and management.

Features and Benefits:

High Availability Features

Redundant Trunk Group (RTG): To avoid the complexities of the Spanning Tree Protocol (STP) without sacrificing network resiliency, the EX2200 employs a redundant trunk group to provide the necessary port redundancy and simplify switch configuration.
Power resiliency through external redundant power supply: The EX2200 supports an optional redundant power supply (RPS) unit which provides power resiliency.

Junos Operating System

The EX2200 runs the same Junos OS used by other Juniper Networks EX Series Ethernet Switches, as well as all of Juniper’s routers and Juniper Networks SRX Series Services Gateways. By utilizing a common operating system, Juniper delivers a consistent implementation and operation of control plane features across all products. To maintain that consistency, Junos OS adheres to a highly disciplined development process that uses a single source code, follows a single quarterly release train, and employs a highly available modular architecture that prevents isolated failures from bringing down an entire system.

These attributes are fundamental to the core value of the software, enabling all Junos OS-powered products to be updated simultaneously with the same software release. All features are fully regression-tested, making each new release a true superset of the previous version; customers can deploy the software with complete confidence that all existing capabilities will be maintained and operate in the same way.

Converged Environments

The EX2200 provides the highest levels of flexibility and features in its class for the most demanding converged data, voice, and video environments, delivering a reliable platform for unifying enterprise communications.

By providing a full 15.4 watts of Class 3 PoE to VoIP telephones, closed-circuit security cameras, wireless access points, and other IP-enabled devices, the EX2200 delivers a future proofed solution for converging disparate networks onto a single IP infrastructure. The EX2200 PoE switches also support 802.3at standards-based PoE+ for powering networked devices like multiple radio IEEE 802.11n wireless access points, and video phones that may require more power than available with IEEE 802.3af.

To ease deployment, the EX2200 supports the industry-standard Link Layer Discovery Protocol (LLDP) and LLDP-Media Endpoint Discovery (LLDP-MED) protocol, enabling the switches to automatically discover Ethernet-enabled devices, determine their power requirements, and assign virtual LAN (VLAN) membership. LLDP-MED-based granular PoE management allows the EX2200 to negotiate PoE usage down to a fraction of a watt on powered devices, enabling more efficient PoE utilization across the switch.

In addition, the EX2200 supports rich quality-of-service (QoS) functionality for prioritizing data, voice, and video traffic. The switches support eight class-of-service (CoS) queues on every port, enabling them to maintain multilevel, end-to-end traffic prioritizations. The EX2200 also support a wide range of policy options, including strict priority, low-latency, weighted random early detection (WRED), and shaped deficit weighted round-robin (SDWRR) queuing.

Security

The EX2200 fully integrates with Juniper Networks Unified Access Control, which consolidates all aspects of a user’s identity, device, and location. This enables administrators to enforce access control and security down to the individual port or user levels.

Working as an enforcement point within UAC, the EX2200 provides both standards-based 802.1X port-level access control for multiple devices per port, as well as Layer 2-4 policy enforcement based on user identity, location, and/or device. A user’s identity, device type, machine posture check, and location can be used to determine whether access should be granted and for how long. If access is granted, the switch assigns the user’s device to a specific VLAN based on authorization policy. The switch can also apply security policies, QoS policies, or both, or it can mirror user traffic to a central location for logging, monitoring, or threat detection by intrusion prevention systems.

The EX2200 also provides a full complement of integrated port security and threat detection features, including Dynamic Host Configuration Protocol (DHCP) snooping, Dynamic ARP Inspection (DAI), and media access control (MAC) limiting to defend against internal and external spoofing, man-in-the-middle and denial of service (DoS) attacks.

Simplified Management and Operations

When deployed in a Virtual Chassis configuration, the EX2200 dramatically simplifies network management. Up to four interconnected EX2200 switches can be managed as a single device utilizing a single Junos OS image file and a single configuration file, reducing the overall number of units to monitor and manage. When the Junos OS is upgraded on the master switch in an EX2200 Virtual Chassis configuration, the software is automatically upgraded on all other member switches at the same time.

The EX2200 includes port profiles that allow network administrators to automatically configure ports with security, QoS, and other parameters based on the type of device connected to the port. Six preconfigured profiles are available, including default, desktop, desktop plus IP phone, WLAN access point, routed uplink, and Layer 2 uplink. Users can select from the existing profiles or create their own and apply them through the command-line interface (CLI), J-Web Software interface, or management system.

In addition, a feature called system snapshot makes a copy of all software files used to run the switch—including the Junos operating system, the active configuration and the rescue configuration—that can be used to reboot the switch at the next power-up or as a backup boot option. The Junos OS software can also be pre-installed on a flash drive and used to boot the EX2200 at any time.

Another feature, called automatic software download, enables network administrators to easily upgrade the EX2200 using the DHCP message exchange process to download and install software packages. Users simply configure the automatic software download feature on EX2200 switches acting as DHCP clients and establish a path to the server where the software package file is installed. The server then communicates the path to the software package file through DHCP server messages.

An EZ touchless provisioning feature allows a DHCP server to push configuration details and software images to multiple switches at bootup.

Three system management options are available for the EX2200 line. The standard Junos OS CLI management interface offers the same granular capabilities and scripting parameters found in any router powered by the Junos operating system. The EX2200 also includes the integrated J-Web interface, an embedded web- based device manager that allows users to configure, monitor, troubleshoot, and perform system maintenance on individual switches via a browser-based graphical interface.

Finally, EX2200 fault, configuration, and performance data can be exported to leading third-party management systems such as HP OpenView, IBM Tivoli, and Computer Associates Unicenter software, providing a complete, consolidated view of network operations.

Junos Space:

Juniper also offers a comprehensive suite of network management tools that provide a smart, simple, and open approach for automating the deployment and operation of a Juniper infrastructure.

These tools are based on a single network application platform called Juniper Networks Junos® Space, an open, programmable application platform for hosting network infrastructure and operational applications across the entire management life cycle of the network. Explicitly designed to allow partners and customers to build and deploy smart, simple, and easy-to-use applications, Junos Space provides multiple management and infrastructure applications for managing Juniper resources and assets, including inventory management, device and interface configuration, automated software management and deployment, and event- driven fault management. These platform applications are embedded within the core product, allowing users to control any part of their environment when used in conjunction with multiple add-on applications. Junos Space will support a full portfolio of applications for automating network infrastructure and operations covering the campus LAN and data center network environments.

Designed to automate the configuration, visualization, monitoring, and administration of large switch and router networks, these Junos Space applications offer predefined automation schemes and best practice templates to enable rapid and accurate deployments. When managing a group of EX2200 switches,

the Junos Space platform and associated applications provide network-level management across all Juniper Networks switches from a single console.
