Layer 2 Managed Switch

GS-5220-46S2C4X L2+ 46-Port 100/1000BASE-X SFP + 2-Port Gigabit TP/SFP + 4-Port 10G SFP+ Managed Switch

Key Features

Physical Port

• 48 100/1000BASE-X mini-GBIC/SFP slots
• 2 10/100/1000BASE-T RJ45 copper ports, shared with port-1 to port-2
• 4 10GBASE-SR/LR SFP+ slots, compatible with 1000BASE-SX/LX/BX SFP
• RJ45 to RS232 DB9 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 of Store-and-Forward architecture, and runt/CRC filtering eliminates erroneous packets to optimize the network bandwidth
• Storm control support
- Broadcast / Unicast / Unknown-unicast
• Supports VLAN
- IEEE 802.1Q tagged VLAN- Up to 255 VLANs groups, out of 4095 VLAN IDs- Provider Bridging (VLAN Q-in-Q) support (IEEE 802.1ad)- Private VLAN Edge (PVE)- Protocol-based VLAN- MAC-based VLAN- IP Subnet-based VLAN- Voice VLAN
• 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 26 trunk groups, up to 8 ports per trunk group- Up to 16Gbps 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

Layer 3 IP Routing Features

• Supports maximum 32 static routes and route summarization

Quality of Service

• Ingress shaper and egress rate limit per port bandwidth control
• 8 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
• Traffic-policing policies on the switch port
• DSCP remarking

Multicast

• Supports IGMP snooping v1, v2 and v3
• Supports MLD snooping v1 and v2
• Querier mode support
• IGMP snooping port filtering
• MLD snooping port filtering
• MVR (Multicast VLAN Registration)

Security

• Authentication
- IEEE 802.1x port-based / MAC-based network access authentication- IEEE 802.1x authentication with guest VLAN- Built-in RADIUS client to cooperate with the RADIUS servers- RADIUS / TACACS+ users access authentication
• Access Control List
- IP-based Access Control List (ACL)- MAC-based Access Control List (ACL)
• Source MAC / IP address binding
• DHCP Snooping to filter distrusted DHCP messages
• Dynamic ARP Inspection discards ARP packets with invalid MAC address to IP address binding
• IP Source Guard prevents IP spoofing attacks
• IP address access management to prevent unauthorized intruder

Management

• IPv4 and IPv6 dual stack management
• Switch Management Interfaces
- Console / Telnet command line interface- Web switch management- SNMP v1, v2c, and v3 switch management- SSH / SSL secure access
• IPv6 Address / NTP management
• Built-in Trivial File Transfer Protocol (TFTP) client
• BOOTP and DHCP for IP address assignment
• System Maintenance
- Firmware upload / download via HTTP / TFTP- Reset button for system reboot or reset to factory default- Dual images
• DHCP relay and option 82
• User privilege levels control
• NTP (Network Time Protocol)
• Link Layer Discovery Protocol (LLDP) and LLDP-MED
• Network diagnostic
- SFP-DDM (Digital Diagnostic Monitor)- Cable diagnostic technology provides the mechanism to detect and report potential cabling issues- ICMPv6 / ICMPv4 remote ping
• SMTP / Syslog remote alarm
• Four RMON groups (history, statistics, alarms and events)
• SNMP trap for interface link up and link down notification
• System Log
• PLANET Smart Discovery Utility for deploy management
