8-port Full L2/L3 Management, plus 2 SFP open slot, Gigabit Ethernet Switch


2 Gigabit SFP Open Slots 

The switch supports 2 additional SFP open slots to uplink to servers, storage, or other switching devices for long reach applications. The 2 SFP slots support legacy 100M SFP transceiver. If the 100M fiber infrastructure is constructed and 100M bandwidth is enough, the 100M SFP transceiver can be an optional choice for the legacy 100M network environment. 

Full Layer 2/3 Management Features 

The switch includes full Layer 2/3 Management features. The software set includes up to 4K 802.1Q VLAN and advanced Protocol VLAN, Private VLAN, MVR…advanced VLAN features. There are 8 physical queues Quality of Service, IPv4/v6 Multicast filtering, Rapid Spanning Tree protocol to avoid network loop, Multiple Spanning Tree Protocol to integrate VLAN and Spanning Tree, LACP, LLDP; sFlow, port mirroring, cable diagnostic and advanced Network Security features. It also provides telnet CLI for management and SNMP, Web GUI for in band Management.

 Advanced Security 

The switch supports advanced security features. For switch management, there are secured HTTPS and SSH, the login password, configuration packets are secured. The port binding allows to bind specific MAC address to the port, only the MAC has the privilege to access the network. The 802.1X port based Access Control, every user should be authorized first when they want to access the network. AAA is the short of the Authentication, Authorization and Accounting with RADIUS, TACAS+ server. Layer 2/3 Access Control List allows user to define the access privilege based on IP, MAC, Port number…etc. 

Optical DDM

 DDM is Digital-Diagnostic-Monitoring which provides a user with critical information concerning the status of the transmitted and received signals. This approach allows for better fault isolation and error detection. Digital diagnostic monitor the SFP module’s temperature, Supply Voltage, and TX, RX, Sensitivity, etc. With these collected digitized values, the system administrator can trigger an alarm and simply record the data into a register. 

Virtual Stacking 

NGSM8T2/NGSM16T2/NGSM24T2 supports Virtual Stacking function, which allows multiple eten switches of different models to stack virtually and managed as a single one switch.
