Ease of Management Supporting Rapid Network Deployment
ReachNXT 100-8t connects to an upstream ExtremeXOS switch via plug-and-play. The auto-discovery function allows the
ReachNXT 100-8t and the ExtremeXOS switch to recognize each other and appear in EPICenter
Single Streamlined Operating
System across the Entire
Enterprise Network
Extreme Networks provides
ExtremeXOS based Ethernet switching
platforms for the edge, aggregation, and
core of the enterprise network. Using
one operating system across the network
significantly simplifies deployment and
operation, as well as ongoing mainte-
nance, to reduce the total cost of
ownership. ReachNXT 100-8t connected
to an ExtremeXOS switch provides a
consistent experience for the user from
core to edge to access of the network.
Link Layer Discovery Protocol
ExtremeXOS supports IEEE 802.1ab
standards-based discovery protocol and
provides vendor-independent device
discovery. LLDP not only simplifies
deployment and location of access
devices, but can also be used as a
troubleshooting and firmware manage-
ment tool. LLDP is an extensible
standard, providing a framework for
industry consortiums to define applica-
tion-specific extensions without causing
compatibility issues.
Efficient and Comprehensive
Network Management
Extreme Networks has developed tools
that help save time and resources in
managing your network. EPICenter
provides fault configuration, accounting,
performance, and security functions,
allowing more effective management of
Extreme Networks multilayer switching
equipment in a converged network.
Optional Power Adapter
The ReachNXT 100-8t enterprise port
extender can be powered by an external
AC power adapter when using the fiber
connection to the upstream
ExtremeXOS switch through its
1000Base-X SFP.
Network Security
The ReachNXT 100-8t does not directly
support VLANs; all its ports are un-
tagged and are part of the same broad-
cast domain. However, by taking
advantage of ExtremeXOS NetLogin
features on the upstream switch, clients
connected to the ReachNXT 100-8t port
extender can logically belong to separate

VLANs. These ExtremeXOS features
include NetLogin, multiple supplicant
support and authentication failure VLAN.
By implementing these features on the
ExtremeXOS switch port that the
ReachNXT 100-8t is connected to, clients
can be assigned to different VLANs. On
the ReachNXT 100-8t the clients are all
one network segment, but once the traffic
hits the ExtremeXOS switch it can be
segregated to different VLANs. Restricted
Guest access can also be granted and this
traffic segregated on a separate VLAN.
NetLogin and
Multiple Supplicant Support
ExtremeXOS supports NetLogin with
multiple clients (supplicants) individually
authenticated on the same port. This
feature makes it possible for two or more
client stations to be connected to the same
port. The clients can be assigned to
specific VLANs based on a VLAN RADIUS
attribute. Authentication can be via
802.1x, MAC-based or via Web (Captive
Portal).
Authentication Failure VLAN
When this feature is enabled on a
NetLogin-enabled port and a NetLogin
client fails authentication, the client is
moved to an authentication failure VLAN.
This VLAN can be a "Guest" VLAN with
restricted access, such as access only to
the public Internet. Restricted access can
be enforced using access control lists,
routing policies and rate limiting. In this
way, the network operator can automate
network login and authentication, thereby
reducing effort and errors.
Theft Deterrents
Implementing a secure network means
providing protection at the network
perimeter as well as the core. In addition,
physical removal of equipment is another
situation the network operator must
address. The ReachNXT 100-8t extends
the hardened network ExtremeXOS
infrastructure for network security. For
physical security, the ReachNXT 100-8t
has deterrents built in its design.
Monitoring Connectivity through
Link Layer Discovery Protocol
As mentioned previously, LLDP not only
simplifies deployment and location of
access devices, but can also be used for
troubleshooting and monitoring. LLDP

allows the ReachNXT 100-8t and the
ExtremeXOS switch to communicate with
each other for connectivity and status
information.
Monitoring ReachNXT 100-8t
on EPICenter
Through an upstream ExtremeXOS switch
such as a member of the Summit
family, EPICenter is able to "see" the
ReachNXT 100-8t in an Extreme Networks
based network. The network operator can
customize EPICenter so that alerts will
appear if ReachNXT 100-8t is removed
from the network.
Kensington Slot for
Physical Security
ReachNXT 100-8t has a Kensington slot so
that it can be attached to a hard-to-move
object.
Ease of Management
and Operations Lower
Network Costs
The plug-and-play nature of
ReachNXT 100-8t with an ExtremeXOS
switch reduces network management and
operational costs. Since ReachNXT 100-8t
and the ExtremeXOS switches use LLDP to
establish connectivity, the network
operator does not have to configure the
ReachNXT 100-8t to be deployed in the
network. Thus, little or no cost is incurred
in deploying ReachNXT 100-8t. Also, since
an ExtremeXOS switch passes device
attachment information to EPICenter,
monitoring of ReachNXT 100-8t is made
much easier. If ReachNXT 100-8t is
disconnected from the network, EPICenter
can notify the network operator to take
action.
Another feature of the combo 1000M port is
that the ReachNXT 100-8t can perform
media conversion from optical signals to
electrical signals through its 1000BASE-X
SFP port to eight of its 10/100BASE-T
ports. This feature is very useful for
distances greater than 100m—which
exceeds the limits of copper cabling—
extending the reach of the network.
