Avaya Ethernet switches
390 Hardware Description and Reference for Avaya Communication Manager
● An advanced election algorithm ensures optimal stack master selection.
● P330-BUPS and P330-ML-BUPS can support BUPS functionality for up to 4 switches
Layer 2 features
● Auto-sensing simplifies configuration of LAN connections by automatically selecting the
port speed for devices — either 10Mb or 100Mb.
● Auto-negotiation simplifies configuration of LAN connections by automatically selecting the
port transmission mode for devices — either half- or full-duplex.
● Traffic prioritization (802.1p) allows real-time traffic classification into 8 priority levels
mapped to 4 queues.
● The use of the IEEE 802.1Q tagging for VLANs and per-port VLAN is supported.
● Multiple VLANs per port allow access to shared resources by stations that belong to
different VLANs.
● The use of the IEEE 802.1w standard for Rapid Spanning Tree Protocol (RSTP) provides
rapid convergence of the spanning tree in case of link failure.
● The use of the IEEE 802.1x standard for port-based network security ensures that only
authorized clients get network access.
● MAC security is supported.
● Port redundancy is supported to increase link resiliency.
● Intermodule redundancy is supported with one pair in a stack.
● Link Aggregation Group (LAG) support provides resiliency, load balancing, and bandwidth
expansion.
● LAG redundancy is supported through resiliency between two LAG groups.
● Port mirroring of any switch port is supported.
● RMON/SMON port statistics provide real-time top-down analysis of network traffic.
● IP multicast filtering (snooping) filters multicast traffic to optimize network bandwidth.
● Classification of ports as regular or valuable is supported so if a link fails, notification is
generated for valuable ports only.
Layer 3 features
Note:
Note: Layer 3 features are available only on the P333R and P330-ML switches.
● Static, RIPv1, RIPv2, OSPF IP routing protocols are supported.
● Equal cost routing is used for load balancing and redundancy.
● Router redundancy (VRRP) is supported.
