LevelOne GEL-2870 User Manual



GEL-2870

H/W Version: 1

LevelOne GEL-2870 is a standalone Layer 2 SNMP 

Gigabit Ethernet switch with 24 1000Base-T Gigabit 

Ethernet ports, 4 Gigabit Ethernet RJ-45 Combo 

ports which associated with SFP (Small Form Factor 

Pluggable) slots. It is a fully managed switch that 

supports power saving, sophisticated QoS and 

VLAN to provide great scalability for mission-critical 

applications. The ports can be aggregated to create 

a high-bandwidth pipe to the network. GEL-2870 

provides comprehensive network management 

functions such as STP/RSTP/MSTP protocol for 

standard bridging, SNMP, RMON and advanced 

security features are supported.

GEL-2870 supports IEEE 802.3ad Link Aggregation 

Control Protocol (LACP) to increase the bandwidth 

by automatically aggregating several links together 

as one logical trunk. It offers load balancing and fault 

tolerance for uplink connections. IGMP snooping 

prevents flooding of IP multicast traffic and limits 

bandwidth intensive video traffic to the subscribers 

only.

Offers advanced QoS for marketing, classification, 

and scheduling to deliver best possible performance 

for data, voice and video traffic at wire speed. Traffic 

is prioritized according to IEEE 802.1p, DSCP, IP 

precedence and TCP/UDP port number to provide 

optimal performance to real-time applications. 

IEEE 802.1Q-in-Q allows service providers to offer 

differentiate services, such as Internet access for 

specific customers with specific VLANs, or to assign 

several VLANs to other customers for specific services.

For IP multicast traffic, GEL-2870 enables IGMP 

snooping to provide fast joins and leaves of multicast 

streaming clients. It prevents flooding of IP multicast 

traffic, and limits bandwidth intensive video traffic 

to the subscribers only. It also supports IPV6 

management in SNMP/Telnet/TFTP.
