Layer 2 Managed Switch

WGSW-28040 24-Port 10/100/1000T + 4-Port Gigabit TP/SFP Combo Managed Switch

Key Features

Physical Port

• 28-Port 10/100/1000Base-T Gigabit RJ45 copper
• 4 100/1000Base-X mini-GBIC/SFP slots, shared with Port-25 to Port-28
• RJ45 console interface for switch 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- 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 / Egress Rate Limit per port bandwidth control
