Hello, We are now looking for indications for a managed top of rack switch for a network research testbed. For the last 3-4 years we have been using a product from a local (Brazilian) provider, but their OpenFlow support did not evolve in the last years, and now we are looking for a new box model that we can use from now on to install new racks or replace units without contract support that are limited to OpenFlow 1.0. We are looking for a box – it cay be a white-box – with the following features: • L2 / L3 switch • 48 Ports 1GbE UTP RJ-45 • Line rate non-blocking wire-speed for 64-byte packets • Minimum of 2 or more ports with 1Gbps mini GBIC (SFP) (support for 2x 10Gbps SFP+ is desirable, but not mandatory) • 1U 19" chassis • 110V / 220V AC Power (redundant is preferable, but not mandatory) • Support for IPv4, IPv6 and OpenFlow • Support for OpenFlow version 1.0.0 and above • Support for VLAN Tagging with simultaneous 4094 active VIDs IEEE 802.1q) • Support for Q-in-Q double tagging with EtherType 0x8100 and selective Q-in-Q • Support for VLAN translation allowing label push, pop or swap (IEEE 802.1q) • Support for Routing between VLANs (IPv4 and IPv6) • Support for management protocols (SNMP etc) • Support for debugging OpenFlow traffic in the CLI • Support for dual images for resilient firmware upgrades is desirable • Support for Secure remote management of the switch via Secure Shell (SSH) and SSL encryption • Support for SNMP versions 1, 2c, and 3 with support for SNMP Traps • Support for port mirroring • Configuration rollback feature is desirable • POE (IEEE 802.3af) is desirable, but not mandatory. Thanks, Alex
