Managed Ethernet Switch

• Compact Ethernet access switch for wire-speed Layer 2 connectivity
• Three Gigabit Ethernet 1000BaseFX SFP ports
• Six Fast Ethernet 10/100BaseT UTP ports
• Ethernet bridging and switching per 802.1D, 802.1Q, 802.1Q-in-Q
• Four QoS priority queues with SP, WFQ scheduling
• ITU-T G.8032 Ethernet Ring Protection Switching (ERPS)
• Power over Ethernet (PoE) support
• Wide range of AC/DC power supplies
• SNTP, Net Inventory and Dying gasp support for management, configuration and diagnostics

Ethernet capabilities and differentiated QoS

The ETX-26 supports VLAN-aware and VLANunaware, as well as VLAN stacking (Q-in-Q) operation. It enables differentiated QoS (quality of service) per port, VLAN priority (P-bit), DSCP, or ToS. The ETX-26 supports four priority queues per Ethernet port with configurable scheduling (Strict Priority or WFQ) to accommodate service requirements of real-time, priority data or besteffort traffic. In addition, the device supports ingress and egress rate limiting to control the use of available bandwidth.

Ethernet ring protection

ETX-26 features Ethernet Ring Protection Switching (ERPS) per ITU-T G.8032, enabling link resiliency with less than 50 ms failover time to ensure high survivability and service continuity in the event of link failures.

Dying gasp and management

The ETX-26 supports fault localization and accurate reporting of critical events to reduce OpEx. Its dying gasp feature enables carriers to pinpoint the reason a customer connection is down (power failure or CPE problem), minimizing costly technician visits for false alarms.

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

• Local management via an ASCII terminal (RS-232)
• Inband management via any of the Ethernet ports
• Remote management via Telnet, Web browser, or an SNMP-based management system
