Availability

Superior

redundancy for

fault backup

• IEEE 802.1D Spanning-Tree Protocol support for redundant backbone connections and

loop-free networks simpliﬁes network conﬁguration and improves fault tolerance.

• Support for Cisco Spanning-Tree Protocol enhancements such as UplinkFast,

BackboneFast,and PortFast technologies ensures quick failoverrecovery, enhancing overall

network stability and availability.

• IEEE 802.1w Rapid Spanning-Tree Protocol (RSTP) provides rapid convergence of the

spanning tree, independent of spanning tree timers.

• 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.

• Provides unidirectional link detection (UDLD) and Aggressive UDLD for detecting and

disabling unidirectional links on ﬁber-optic interfaces caused by incorrect ﬁber-optic wiring

or port faults.
