Layer 2 Features

- IEEE 802.1Q tagged VLAN- Provider Bridging (VLAN Q-in-Q) support (IEEE 802.1ad)- Protocol VLAN- Voice VLAN- Private VLAN (Protected port)- Management VLAN- GVRP- STP (Spanning Tree Protocol)- RSTP (Rapid Spanning Tree Protocol)- MSTP (Multiple Spanning Tree Protocol)- STP BPDU Guard, BPDU Filtering and BPDU Forwarding- IEEE 802.3ad Link Aggregation Control Protocol (LACP)- Cisco ether-channel (static trunk)- Maximum 8 trunk groups, up to 8 ports per trunk groupPrevents packet loss with back pressure (half-duplex) and IEEE 802.3x pause frame flow control (full-duplex)High performance Store and Forward architecture, runt/CRC filtering eliminates erroneous packets to optimize the network bandwidthSupports VLANSupports Spanning Tree ProtocolSupports Link AggregationProvides port mirror (many-to-1)Loop protection to avoid broadcast loops
