Layer 2 Features
■ Prevents packet loss with back pressure (half-duplex) and IEEE 802.3x pause frame flow control (full-duplex)
■ High performance Store and Forward architecture, broadcast storm control, and runt/CRC filtering that eliminates
erroneous packets to optimize the network bandwidth

- IEEE 802.1Q tagged VLAN
- Provider Bridging (VLAN Q-in-Q) support (IEEE 802.1ad)
- Protocol VLAN
- Voice VLAN
- Private VLAN
- Management VLAN
- GVRP
■ Supports Spanning Tree Protocol
- STP (Spanning Tree Protocol)
- RSTP (Rapid Spanning Tree Protocol)
- MSTP (Multiple Spanning Tree Protocol)
- STP BPDU Guard, BPDU filtering and BPDU forwarding
■ Supports Link Aggregation
 IEEE 802.3ad Link Aggregation Control Protocol (LACP)
 Cisco ether-channel (static trunk)
■ Provides port mirror (many-to-1)
■ Loop protection to avoid broadcast loops
■ Supports ERPS (Ethernet Ring Protection Switching)
Quality of Service
■ Ingress and egress rate limit per port bandwidth control
■ Storm control support
 Broadcast/Unknown unicast/Unknown multicast
■ Traffic classification
- IEEE 802.1p CoS
- TOS/DSCP/IP precedence of IPv4/IPv6 packets
■ Strict priority and Weighted Round Robin (WRR) CoS policies
Multicast
