GEL-2670 Version: 1
26-Port L2 Managed Gigabit Ethernet Switch, 2 x
SFP
The LevelOne GEL-2670 is an intelligent L2 Managed Switch with 24 x 1000Base-T ports and 2 x
100/1000BASE-X SFP (Small Form Factor Pluggable) slots. Ideal for desktops, it is also 19-inch rack-
mountable, which provides convenient and flexible installation.
The switch supports a flexible web-based management interface SNMP for both IPv4 and IPv6 as well as
layer 2 management features. Despite its affordable pricing, the GEL-2670 is equipped with many
advanced features such as Internet Group Management Protocol (IGMP) snooping V1/V2/V3, VLANs, IEEE
802.1D/w/s Spanning Tree, Access Control List (ACL) of up to 256 entries for easy network security, Link
Aggregation Control Protocol (LACP), IEEE 802.1p QoS with 8 priority queues, UPnP for auto-discovery
and configuration of devices, Storm Control for protecting against broadcast/multicast/unknown unicast and
much more.
An ideal network solution for workgroups and edge deployments, or anyone looking for an affordable and
efficient way to expand their network.
