GS-4210-48T4S

Description

Physical Port

• 48-port 10/100/1000BASE-T Gigabit RJ45 copper
• 4 100/1000BASE-X mini-GBIC/SFP slots
• Reset button for system factory default
• RJ45 console interface for basic management and setup

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, runt/CRC filtering eliminates erroneous packets to optimize the network bandwidth
• Supports VLAN

– 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

• 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)- Maximum 8 trunk groups, up to 8 ports per trunk group

• Provides port mirror (many-to-1)
• Loop protection to avoid broadcast loops

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
