GS-4210-48T4S – 48 Port Gigabit Managed Switch with 4 Port SFP

Out of stock

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

Multicast

  • Supports IPv4 IGMP snooping v2 and v3
  • Supports IPv6 MLD snooping v1, v2
  • IGMP querier mode support
  • IGMP snooping port filtering
  • MLD snooping port filtering

Security

  • Authentication

- IEEE 802.1X port-based network access authentication- Built-in RADIUS client to co-operate with the RADIUS servers- DHCP Option 82- RADIUS / TACACS+ authentication

  • Access Control List

- IPv4 / IPv6 IP-based ACL- IPv4 / IPv6 IP-based ACE- MAC-based ACL- MAC-based ACE

  • MAC Security

- Static MAC- MAC Filtering

  • Port security for source MAC address entries filtering
  • 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
  • DoS attack prevention
  • SSH/SSL

Management

  • IPv4 and IPv6 dual stack management
  • Switch Management Interface

- IPv4 / IPv6 Web switch management- Telnet Command Line Interface- SNMP v1, v2c and v3- HTTPs secure access

  • Built-in Trivial File Transfer Protocol (TFTP) client
  • User privilege levels control
  • Static and DHCP for IP address assignment
  • System Maintenance

- Firmware upload / download via HTTP / TFTP- Configuration upload / download through HTTP / TFTP- Dual images- Hardware reset button for system reset to factory default

  • SNTP Network Time Protocol
  • Cable diagnostics
  • Link Layer Discovery Protocol (LLDP) and LLDP-MED
  • SNMP trap for interface Link Up and Link Down notification
  • Event message logging to remote Syslog server
  • Four RMON groups (history, statistics, alarms and events)
