The LevelOne GSW-2490TXM SNMP is a managed Fast Ethernet switch, that provides a number of exceptional features with extremely flexible configuration expansions without compromising the wire speed performance.
The LevelOne GSW-2490TXM SNMP switch provide wire-speed switching with advanced bridging functions like VLAN, priority, multicast filtering, link aggregation and port mirroring. It can also support two different GBIC type as Mini GBIC LC and standard
GBIC SC.
Many comprehensive network management functions are provided, such as Spanning Tree protocol for loop prevention and full recovery, VLAN configuration and IGMP snooping for multicast grouping configuration. VT100 console, remote telnet login, SNMP, and Web Interfaces are all standard management features.
