ETX-1 is an entry level Ethernet demarcation switch, part of RAD’s Service Assured Access (SAA) solution, and providing Ethernet connectivity services for business applications. Combining switch functionality with basic Ethernet demarcation capabilities, ETX-1 enables quick, cost-effective service deployment to meet enterprise demand for Ethernet Private Line connectivity and LAN-to-LAN interworking. ETX-1 features Ethernet QoS, OAM and diagnostics to lower OpEx associated with service provisioning and monitoring. In addition, built-in switch functionalitiesallow local service provisioning within the organization, without the need to traverse the operator’s network.

MARKET SEGMENTS AND APPLICATIONS

ETX-1 is a demarcation point for service providers enabling control and monitoring of the network starting at the customer site. Supporting standard based Operations, Administration and Maintenance (OAM) and QoS mechanisms, it enables operators to provide Carrier Ethernet services from the network hand-off point.

ETHERNET

ETX-1 introduces a six-port, full line rate wire-speed VLAN-aware GbE switch with 9-kB jumbo frame support. 

QoS

ETX-1 supports six Classes of Service per network port and four Classes of Service per user port with configurable strict priority and/or Weighted Round Robin priority mechanisms. Traffic is shaped at the port egress or per network queue.

Classification

Traffic is mapped to Ethernet flows (EVCs) using the following per-port classification criteria:

• Port-based (all-to-one bundling)
• P-bit (802.1p)
• VLAN ID
• IPv4 ToS/DSCP
• Source/destination IP address.

The following per-flow actions are supported:

• Rate limiting with 64-kbps granularity
• 802.1ps/P-bit remarking
• VLAN stacking.

Ethernet OAM

Single segment (link) OAM according to IEEE 802.3-2005 (formerly 802.3ah) provides fault indication, including remote loopback.
End-to-end OAM based on IEEE 802.1ag enables Ethernet service providers to monitor their services proactively and ensure service availability.
End-to-end service and performance monitoring based on ITU-T Y.1731 assures fault monitoring and end-to-end performance measurement including delay, delay variation, frame loss and availability. L2CP
The device can be configured to pass through Layer-2 control frames (including other vendors’ L2CP frames) across the network, to peer supported protocols, or to discard the frames.

MANAGEMENT AND SECURITY

Management

The unit can be managed using the following ports and applications:

• Local out-of-band management access via a dedicated serial management port (mini-USB).
• Remote inband management via the network ports, or out-of-band via dedicated Ethernet port, using Telnet or RADview, RAD’s SNMP-based network management system.

Command Line Interface

Databases and scripts of commonly used commands can be easily created and applied to multiple units using command line interface.

Security

The following security protocols ensure client server communication privacy and correct user authentication:

• SNMPv3
• RADIUS (client authentication)
• TACACS+ (client authentication and accounting)
• SSH for secure shell communication session
• SFTP for secure file transfer.
