The XChange3021 is a conduction- or air-cooled, 3U OpenVPX™ integrated switch module supporting both PCI Express and Ethernet protocols. The integrated PCI Express and Ethernet switch functionality allow XChange3021 to serve as the heart of inter-board communications inside a high-end OpenVPX™ system. Additionally, external Gigabit Ethernet and/or 10 Gigabit Ethernet links provide connectivity between the OpenVPX™ system and the outside world.The XChange3021 supports x4 width Gen3 (backwards compatible with Gen1 and Gen2) PCI Express links between up to 6 slots in an OpenVPX™ backplane to facilitate high-bandwidth, memory mapped communications between the payload boards. In addition, a x8 PCIe link is provided to an onboard XMC mezzanine site to allow for onboard I/O and protocol expansion.The XChange3021’s Ethernet switch supports various configurations of up to ten 10 Gigabit or Gigabit Ethernet ports. The Ethernet switch supports jumbo packets up to 12 kB, IPv6, Energy Efficient Ethernet (EEE), and a comprehensive set of IETF RFCs and IEEE protocols. The XChange3021 also supports compliance with the VICTORY specification as an Infrastructure Switch and Router.When configured as a fully managed Layer 2 switch, support for features such as fast boot, flow control, MAC bridging (IEEE 802.1D), port mirroring, port authentication (IEEE 802.1x), VLANs (IEEE 802.1Q), Quality of Service (QoS), GVRP, MVRP, port and protocol classification (IEEE 802.1v), GARP, MRP, GMRP, MMRP, LACP, RMON, STP, RSTP, MSTP, RPVST+, AgentX, and IGMP are included. When configured as a Layer 3 router, support for Multicast and Unicast Routing features such as DVMRP, IGMP, PIM-DM, PIM-SM, PIM-SSM, MLD, RIP, BGP, OSPFv2/OSPFv3, and VRRP are added.When paired with the optional XPedite5205 XMC/PMC router module, the XChange3021 includes Cisco IOS® IP routing and Cisco Mobile Ready Net capabilities. With this technology, the router provides highly secure data, voice, and video communications to stationary and mobile network nodes across both wired and wireless links. With the XPedite5205, Cisco IOS® security features are also supported, including hardware encryption, firewalls with integrated threat control, zone-based firewalls, Intrusion Prevention System (IPS), content filtering, identity management using Authentication, Authorization, and Accounting (AAA), and Public Key Infrastructure (PKI).
