Stacking
- Hardware stack up to 16 units and 384 Gigabit ports
- Single IP address stack management
- Stacking architecture supports Chain and Ring mode
- Plug and Play connectivity
- Mirror across stack
- Link Aggregation groups spanning multiple switches in a stack
- Hardware learning with MAC table synchronization across stack
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, broadcast storm control and runt / CRC filtering eliminates erroneous packets to optimize the network bandwidth
- Storm Control support: – Broadcast / Multicast / Unknown-Unicast
- Supports VLAN – IEEE 802.1Q Tagged VLAN– Up to 255 VLANs groups, out of 4041 VLAN IDs– Provider Bridging (VLAN Q-in-Q) support (IEEE 802.1ad)– Private VLAN Edge (PVE)
- Supports Spanning Tree Protocol – STP, IEEE 802.1d (Spanning Tree Protocol)– RSTP, IEEE 802.1w (Rapid Spanning Tree Protocol)– MSTP, IEEE 802.1s Multiple Spanning Tree Protocol, spanning tree by VLAN– BPDU Guard
- Supports Link Aggregation – 802.3ad Link Aggregation Control Protocol (LACP)– Cisco ether-channel (Static Trunk)– Maximum 12 trunk groups, up to 16 ports per trunk group– Up to 32Gbps bandwidth (Duplex Mode)
- Provides Port Mirror (many-to-1)
- Port Mirroring to monitor the incoming or outgoing traffic on a particular port
Quality of Service
- Ingress Shaper and Egress Rate Limit per port bandwidth control
- 4 priority queues on all switch ports
- Traffic classification: – IEEE 802.1p CoS– TOS / DSCP / IP Precedence of IPv4/IPv6 packets– IP TCP/UDP port number– Typical network application
- Strict priority and Weighted Round Robin (WRR) CoS policies
- Supports QoS and In/Out bandwidth control on each port
- Ingress Shaper and Egress Rate Limit per port bandwidth control
- Traffic-policing policies on the switch port
- QoS Control List Wizard makes QoS creation and configuration easier and more quickly
- DSCP remarking
- Voice VLAN
Multicast
- Supports IGMP Snooping v1, v2 and v3
- Querier mode support
