Description

ComEth4070a 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.

ComEth4070a supports full-wire speed L2 bridging and L3 routing with L2-L4 advanced traffic classification, filtering and prioritization. For instance, it can provide strict priority traffic needed for delay-sensitive or critical applications.

ComEth4070a ports are compatible with VME64x system. Basically twenty GigaEthernet are routed on the P0 P2 rear connectors. The four remaining Giga Ethernet channels are available on the front or on P2. The front option can provide four 1000BT (RJ45) ports or optionally 1000SX/LX fiber channels. The Gigabit transceivers select automatically the media with activity.

Auto-crossover, auto-polarity, auto-negotiation and automatic MAC address management make ComEth4070a a true Plug&Play switch.

The Marvell Virtual Cable tester allows a remote identification of potential cable malfunctions as excessive pair skew, cable opens, impedance mismatch...

This switch is fully functional compatible with ComEth4000a, 4020a, 4030a and 4050a range.

The ComEth4070a 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 easier the maintenance of this switch. 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 by a full-wire speed L3 engine router.

New security services will be added to improve your network protection : quarantine VLAN, MAC & IP addresses localization management, etc.

ComEth4070a can be used as an open switching platform to implement specific functionalities.

Its 6U form factor allows the ComEth4070a to be integrated in VME64x or stand-alone applications. ComEth4070a is available from Standard to Conduction-Cooled grade.
