1 INTRODUCTION
OVERVIEW
The
LGB6026A
and
LGB6050A
Switches are intelligent multilayer switches (Layer
2, 3) with 24/48 10/100/1000BASE-T ports, four of which are combination
ports1 that are shared with four SFP transceiver slots (see Fi gure 1, Ports 21-
24/45-48). The rear panel provides two slots for single-port 10 Gigabit Etherne t
hot-swappable expansion modules (LGB6001C), and two stacking p orts. 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 o ut-of-band access for managing the
stack.
These switches can easily tame your network with full
support
for
Spanning Tree
Protocol, Multicast Switching, Vi r tu al L ANs, an d IP r outi ng. I t brings order to
poorly performing networks by segregating them into separate broadcas t
domains with IEEE 802.1Q compliant VLANs, empowers multimedia applications
with multicast switching and CoS services, and eliminates conve ntional 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.

ports 21-24 on LGB6026A or ports 45-48 on LGB6050A.
