Key Features
Physical Port
- 48-Port 10/100/1000Base-T RJ45 copper
- 4 100/1000Base-X mini-GBIC/SFP slots, shared with Port-45 to Port-48 compatible with 100Base-FX SFP
- 4 10GBase-SR/LR SFP+ slots, compatible with 1000Base-SX/LX/BX SFP
- RJ-45 to RS-232 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
