Fully manageable
The switch is fully managed, supporting SNMP version 1, 2c, and
3. The embedded RMON software agents support RMON groups 1
(history), 2 (statistics), 3 (alarms), and 9 (events). For easy
deployment, LLDP/LLDP-MED features aid the switch in discovering
neighboring devices on a network.

Support for VLAN and QoS
The switch supports up to 4000 simultaneous VLANs for
isolating guest traffic from your critical corporate network traffic.
You can segment traffic with port-based, 802.1Q tag-based, or
MAC-based VLANs.

Plus, you can also program higher-layer classification and
prioritization for reliable Quality of Service (QoS).802.1p Layer 2

Highly secure
You get enterprise-class security features, too. In addition to the
switch’s VLAN support, it boasts 802.1X port-based network access
control for authenticating devices connecting to your network.

In addition, the switch supports SNMPv3 cryptographic security,
SSH, and SSL for remote management via a connection that
encrypts the packet content at each session. And by using its
extensive ACLs (up to 256 entries total), you can keep guests
or unauthorized users from accessing sensitive portions of
your network.

10-Port Gigabit Managed Switch (LGB1108A)
This capable Layer 2+ switch offers eight autosensing 10-/100-
/1000-Mbps RJ-45 Ethernet ports and has a switching capacity of
20 Gbps. Additionally, it has two dual-media ports, each of which
consists of a 10-/100-/1000-Mbps RJ-45 port plus an SFP port.
These dual-media ports can be used either as a normal UTP
Ethernet port or adapted to 100- or 1000-Mbps fiber through the
use of an SFP.
