The LGS103AE and LGS104AE Switches are intelligent multilayer switches (Layer
2, 3) with 24/48 10/100/1000BASE-T ports, four of which are combination
ports
1
that are shared with four SFP transceiver slots (see Figure 1 , Ports 21-
24/45-48). The rear panel provides two slots for single-port 10 Gigabit Ethernet
hot-swappable expansion modules, and two stacking ports. Units can be stacked
up to eight high through the built-in stacking ports that provide a 48
Gbps stack backplane.
The switches include an SNMP-based management agent embedded on the main
board, which supports both in-band and out-of-band access for managing the
stack.
These switches can easily tame your network with full support for Spanning Tree
Protocol, Multicast Switching, Virtual LANs, and IP routing. It brings order to
poorly performing networks by segregating them into separate broadcast
domains with IEEE 802.1Q compliant VLANs, empowers multimedia applications
with multicast switching and CoS services, and eliminates conventional router
bottlenecks.
These switches can be used to augment or completely replace slow legacy
routers, off-loading local IP traffic to release valuable resources for non-IP
routing or WAN access. With wire-speed performance for Layer 2 and Layer 3,
these switches can significantly improve the throughput between IP segments or
VLANs.
1. If an SFP transceiver is plugged in, the corresponding RJ-45 port is disabled for
ports 21-24 on LGS103AE or ports 45-48 on LGS104AE.
