Juniper EX2300 12P POE Network Switch Virtual Chassis Technology

The EX2300-C supports Juniper’s unique Virtual Chassis technology, enabling up to four interconnected EX2300-C switches to be managed as a single logical device and delivering a scalable, pay-as-you-grow solution for expanding network environments.

The EX2300-C can also be connected to an existing Virtual Chassis configuration composed of EX2300 switches.

While EX2300-C switches can be interconnected over either of the two front panel 10GbE uplink ports, these ports can also be configured as 1GbE uplinks to aggregation devices by disabling the Virtual Chassis technology.

When deployed in a Virtual Chassis configuration, the EX2300-C switches elect a primary and a backup switch based on a set of preconfigured policies or criteria.

The primary 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.

EX2300-C Virtual Chassis configurations operate as highly resilient unified systems, providing simplified management using a single IP address, single telnet/SSH session, single command-line interface (CLI), automatic version checking, and automatic configuration.

The EX2300-C 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.

EX2300-C 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.

Juniper EX2300 12P POE Network Switch Simplified Operations

Virtual Chassis technology simplifies network management for smaller deployments.

Up to four interconnected EX2300-C switches can be managed as a single device utilizing a single Junos OS image and a single configuration file, reducing the overall number of units to monitor and manage.

When the Junos OS is upgraded on the primary switch in an EX2300-C Virtual Chassis configuration, the software is automatically upgraded on all other member switches at the same time.

Dedicated front panel RJ-45 and USB console ports offer flexible out-of-band management options, while a front panel USB port can be used to easily upload the Juniper Networks Junos operating system and configuration files.

All front panel access and uplink ports have dedicated link status and link activity LEDs.

In addition, a series of front panel LEDs offer system status information with a button that allows users to toggle through four different modes for reporting speed (SPD), duplex mode (DX), administrative status (EN), and PoE status (PoE). A fixed internal power supply ensures operational simplicity.

Easy Provisioning

Auto-configuration and Auto-Image Install features allow the switches to be configured and imaged over the network using the Dynamic Host Configuration Protocol (DHCP) message exchange process.

These features eliminate the need to stage devices prior to deployment, dramatically reducing operational expenses.

Auto-configuration and Auto Image Install allow new branches and retail stores to rapidly deploy their networks, and they also enable software upgrades and security fixes to be performed at the touch of a button.

The ZTP feature allows a DHCP server to push configuration details and software images to multiple switches at boot-up time.

Juniper EX2300 12P POE Network Switch Campus Fabric Deployments

Juniper campus fabrics support these validated architectures with the EX2300-C switch playing the role of access switch in a Virtual Chassis:

  • EVPN multihoming (collapsed core or distribution) : A collapsed core architecture combines the core and distribution layers into a single switch, turning the traditional three-tier hierarchal network into a two-tier network. This eliminates the need for STP across the campus network by providing multihoming capabilities from the access to the core layer.
    EVPN multihoming can be deployed and managed using the Juniper Mist cloud.
  • Core-Distribution : A pair of interconnected EX Series core or distribution switches provide L2 EVPN and L3 VXLAN gateway support.
    The EVPN-VXLAN network between the distribution and core layers offers two modes : centrally or edge routed bridging overlay.

In all these EVPN-VXLAN deployment modes, EX2300-C switches can be used at the access layer

The fanless design reduces the power consumed by the EX2300-C switches.

Energy Efficient Ethernet (EEE) ports ensure low power consumption when the network link is idle.

Access Security

Working as an enforcement point within the Access Policy Infrastructure, the EX2300-C provides standards-based 802.1X port-level access control as well as L2-L4 policy enforcement based on user identity, location, device, or a combination of these.

If access is granted, the switch assigns the user to a specific VLAN based on authorization levels.

The EX2300-C also provides a full complement of port security features, including DHCP snooping, dynamic ARP inspection (DAI), and media access control (MAC) limiting to defend against internal and external spoofing, and man-in-the-middle and denial-of-service (DoS) attacks.

Physical Security

Security slots on either side of the switch accept locking devices that physically secure switches, preventing them from being easily removed in open space or unsecured environments.
