ABB UFC 912 A101 3BHE039426R0101 Differential expansion module

Resiliency and high availability • Smart continuous switching technology for instantaneous and transparent CMM failover in redundant CMM configuration 

• MC-LAG active-active dual homing over IEEE 802.3ad (LACP) interfaces enabling a highly resilient architecture 

• ISSU for non-disruptive maintenance software upgrade in redundant CMM configuration 

• ITU-T G.8032 Ethernet Ring Protection (ERPv2) designed for loop protection and fast convergence times (sub 50 ms) in ring topologies

• Ring Rapid Spanning Tree (RRSTP) optimized for ring topology to provide less than 100-ms convergence time 

• IEEE 802.1s Multiple Spanning Tree Protocol (MSTP): Encompasses IEEE 802.1D Spanning Tree Protocol (STP) and IEEE 802.1w Rapid Spanning Tree Protocol (RSTP)

• Per-VLAN Spanning Tree (PVST+) and Alcatel-Lucent 1x1 STP mode 

• IEEE 802.3ad Link Aggregation Control Protocol (LACP) and static LAG groups across modules are supported 

• Dual-home link support for sub-second link protection without STP 

• Virtual Router Redundancy Protocol (VRRP) to provide highly available routed environments 

• Bidirectional Forwarding Detection (BFD) for fast failure detection and reduced re-convergence times in a routed environment 

• Broadcast, unknown unicast and multicast storm control to avoid degradation in overall system performance 

• Redundant and hot-swappable power supplies, transceiver modules offering uninterruptible service

Advanced security Access control 

• AOS Access Guardian framework for comprehensive user-policy-based network access control (NAC) • Auto-sensing 802.1X multi-client, multi-VLAN 

• MAC-based authentication for non-802.1x hosts 

• Web-based authentication (captive portal): A customizable web portal residing on the switch that can be used for authenticating supplicants as well as non-supplicants 

• Group mobility rules and “guest” VLAN support
