IP Stacking Management
The XGS3-24242 supports IP stacking function that helps network managers to
easily configure up to 24 switches in the same series via one single IP address
instead of connecting and setting each unit one by one. The IP stacking technology
groups PLANET XGS3-24242 and SGS-6341 series together to enable centralized
management through a single unit, regardless of physical location or switch type,
as long as they are connected to the same local network.

High Reliability Hardware Stacking
Two of the 10G SFP+ ports are used to connect several XGS3-24242 units to
build a virtually logical facility. The XGS3-24242 gives the enterprises, service
providers and telecoms flexible control over port density, uplinks and switch stack
performance. The XGS3-24242 can connect as a ring for redundancy and ensures
that data integrity is retained even if one switch in the stack fails. You can even hot-
swap switches without disrupting the network, which greatly simplifies the tasks of
upgrading the LAN for catering to increasing bandwidth demands.
Layer 3 Routing Support
The XGS3-24242 enables the administrator to conveniently boost network efciency
by configuring Layer 3 static routing manually, and the RIP or OSPF settings
automatically. The RIP can employ the hop count as a routing metric and prevent
routing loops by implementing a limit on the number of hops allowed in a path
from the source to a destination. The OSPF is an interior dynamic routing protocol
for autonomous system based on link state. The protocol creates a database for
link state by exchanging link states among Layer 3 switches, and then uses the
Shortest Path First algorithm to generate a route table based on that database.
Full IPv6 Support
The XGS3-24242 provides IPv6 management and enterprise-level secure features
such as SSH, ACL, WRR and RADIUS authentication. It thus helps the enterprises
to step in the IPv6 era with the lowest investment. In addition, you don’t need to
replace the network facilities when the IPv6 FTTx edge network is built.
