RICi-E3 Connects Fast Ethernet LANs over E3 circuits
RICi-E3 is an intelligent converter connecting Fast Ethernet LANs over E3 circuits. The RICi-E3 enables service providers and ISPs to supply transparent Ethernet services, without interfering with user traffic. RICi-E3 has one unframed E3, and one 10/100BaseTx port. Packets are forwarded from the Ethernet network to the E3 network at wire-speed, fully utilizing the expensive E3 circuit. The 802.1p priority scheme enables users to define three different QoS levels, according to the application requirements. The Fast Ethernet bridge handles 1536-byte frames supporting VLAN applications. In filter mode, the bridge learns MAC addresses and filters local traffic, and in transparent mode it forwards any received packet.
VLAN stacking transports user traffic transparently, keeping the user LAN settings intact. In addition, the management traffic may be tagged with a different VLAN tag, fully separating user traffic from management data. The DHCP client automatically obtains the IP address, IP mask and default gateway, minimizing installation time.
The RAD RICi-E3 features fault propagation. When RICi-E3 detects a link failure, it shuts down the user port.
RICi-E3 Management
RADview Lite, RAD’s SNMP-based system provides fault management and monitoring, with a GUI cut-through to ConfiguRAD, a Web-based tool for element configuration and diagnostics. The RICi-E3 can also be managed via an ASCII terminal or Telnet. Inband management is performed from the Fast Ethernet user port or via the E3 port. Management traffic and user Ethernet traffic are transported together on the same Ethernet flow, separated by different VLAN tags to ensure traffic security.
RICi-E3 Diagnostics
Remote and local loopbacks are used for problem isolation at the physical layer. A built-in ping utility allows checking IP connectivity by pinging remote IP hosts. A trace route application quickly maps a route from RICi-E3
to any other network device.
