Hardware
•
XRE200 External Routing Engine—The XRE200 External Routing Engine is used to
create a Virtual Chassis composed of Juniper Networks EX8200 Ethernet Switches. A
Virtual Chassis is multiple switches connected together that operate as a single network
entity. The advantages of connecting multiple EX8200 switches into a Virtual Chassis
include better-managed bandwidth at a network layer, simplified configuration and
maintenance because multiple devices can be managed as a single device, and a
simplified Layer 2 network topology that minimizes or eliminates the need for
loop-prevention protocols such as Spanning Tree Protocol (STP).
•
New optical transceiver support—The SFP+ uplink module in EX4500 switches now
supports one new optical transceiver: EX-SFP-10GE-LRM (10GBase-LRM, 220 m).
