Layer 3 Features

IP dynamic routing protocol supports OSPFv2 IPv4/IPv6 hardware static routing Routing interface provides per VLAN routing mode IP interfaces (Max. 128 VLAN interfaces) Routing table (Max. 128 routing entries)

Layer 2 Features

Prevents packet loss with back pressure (half-duplex) and IEEE 802.3x pause frame flow control (full-duplex) High performance of Store-and-Forward architecture and runt/CRC filtering eliminates erroneous packets to optimize the network bandwidth Storm Control support Broadcast/multicast/unknown unicast Supports VLAN Supports VLAN IEEE 802.1Q tagged VLAN Supports provider bridging (VLAN Q-in-Q, IEEE 802.1ad) Private VLAN Edge (PVE) Protocol-based VLAN MAC-based VLAN Voice VLAN GVRP (GARP VLAN Registration Protocol) Up to 4K VLANs groups, out of 4094 VLAN IDs Supports Spanning Tree Protocol IEEE 802.1D Spanning Tree Protocol (STP) IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) IEEE 802.1s Multiple Spanning Tree Protocol (MSTP), spanningtree by VLAN BPDU Guard Supports Link Aggregation 802.3ad Link Aggregation Control Protocol (LACP) Cisco ether-channel (static trunk) Maximum 4 trunk groups with 4 ports for each trunk group Up to 80Gbps bandwidth (full duplex mode) Provides port mirror (many-to-1) Port mirroring to monitor the incoming or outgoing traffic on a particular port Loop protection to avoid broadcast loops Supports ERPS (Ethernet Ring Protection Switching) Compatible with Cisco uni-directional link detection(UDLD) that monitors a link between two switches and blocks the ports on both ends of the link if the link fails at any point between the two devices Link Layer Discovery Protocol (LLDP)

Power Management

Dual redundant modular power supply slots Supports configurable power operation modes Redundant Power Supply (RPS, 1+1): Provides 1+1 power redundancy when two PSUs are installed. Extended Power Supply (EPS, 2+0): Provides more power budgetby combining two PSUs to share the maximum power budget Active-active redundant power failure protection Backup of catastrophic power failure on one supply Fault tolerance and resilience
