Description

ComEth4020a is built on the latest generation of Gigabit switch engine and PHY transceiver. It combines a layer 2+ switch and a full layer 3 router in a single equipment with an optimized power consumption.

ComEth4020a supports full-wire speed L2 bridging and L3 routing with L2-L4 advanced traffic classification, filtering and prioritization. The queue priority eight levels combined with QoS policy make easier the jitter tuning in critical applications.

ComEth4020a is designed to optimize the mixed switched networks integration. The twelve rear Giga channels allow an easy integration in a PICMG2.16 PSB when the 12 front fiber ports carry out the optical network connections. This high level of flexibility only requires one slot in the chassis. Many types of transceivers are available for multi-mode or single mode fiber transmission. One front channel operates in fiber or 10/100/1000BT mode with an automatic interface selection.

The optical interfaces provide a full immunity against radiated or conducted interferences. Fiber lines can be routed regardless of high power conductors. These interfaces easily comply with EMC directives and provide a completed electrical isolation. ComEth4020a optical channels are the best solution to secure critical data transmission.

The switch functions are fully compatible with ComEth4000, 4030a and 4050a ranges.

Management Capabilities

The ComEth4020a can be monitored from a browser, a remote application via UDP or SNMP. The whole system can be easily managed and handled. A comprehensive Built-In Test makes the maintenance of this switch easier. Many additional functions are provided on this full-managed version :

Configuration of all the PHY and switch parameters: ports monitoring, static MAC address, QoS policy, Multicast and VLAN control, STP/RSTP protocols, MAC security

Monitoring of all statistical counters and an extensive list of RMON counters

The Switchware software provides layer 3 functions, allowing local IP forwarding (IPv4/ IPv6), static and dynamic protocols (RIP, OSPF) routing, proxy-ARP and DHCP-relay. These L3 functions are managed through a CLI interface. The IP routing and the L3 protocols are carried out by the processor and the forwarding is carried out by a full-speed L3 router.

ComEth4020a can be used as an open switching platform to implement specific functio-nalities.

Flexible configurations

Its 6U form factor allows the ComEth4020a to be integrated in VME VITA31.1, cPCI 2.16 or stand-alone applications. A rear transition module can be used to connect the rear ports on a 6U rear panel.
