Purpose-Built Next-Generation
Ethernet Access Switches for
Metro Ethernet ETTH Market
• All front access provides ease of deployment and troubleshooting in the field.
• Compact form factor (1RU x 9.52 in.) allows for deployment in space-limited areas.
• Dual-speed SFP transceivers support (100 and 1000 MB) provide flexible uplink options.
• Both AC and DC power options are available.
• Software is optimized for triple-play services.
Availability and Scalability
Superior Redundancy for
Fault Backup
• IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) provides rapid spanning-tree convergence
independent of spanning-tree timers and offers the benefit of distributed processing.
• Per-VLAN Rapid Spanning Tree (PVRST+) allows rapid spanning-tree reconvergence on a per-VLAN
spanning-tree basis, without requiring the implementation of spanning-tree instances.
• Unidirectional Link Detection Protocol (UDLD) and Aggressive UDLD allow unidirectional links caused
by incorrect fiber-optic connections or port faults to be detected and disabled on fiber-optic interfaces.
• Switch-port autorecovery (errdisable) automatically attempts to reactivate a link that is disabled
because of a network error.
