Definitions
A trademark is often categorized as a word, name, text, graphic, symbol, logo, icon, image,
device, and/or software or any combination used by a corporation to identify their products and
distinguish those products from other corporations.
A service mark is typically used to identify a corporation’s services rather than tangible
products.
A tradename is commonly used as the name of a corporation or an abbreviation of that name
under which normal business activity is conducted. Some tradenames might be used in more
than one category; therefore, it is important that the reader be aware of the context for which
the tradename is used.
Categories
Trademarks, service marks, and tradenames generally fall into two categories:

LE-3xx/LE-4xx Hardware Installation & User Guide
1. Those that are registered with the United States Patent and Trademark Office1
(USPTO).
2. Those that are being used, but have not yet completed the registration process.
Both categories are protected, although those that are registered provide visible notice of the
corporation’s rights and stronger enforcement provisions.
The registration process may take a long period of time before it is finalized, thus pending
trademarks, service marks, and tradenames may be in use by the corporation.
Trademarks, service marks, and tradenames must be used with the first mention or most
prominent appearance in a publication, but need not be used with each subsequent appearance.
If there are multiple uses of trademarks, service marks, and tradenames throughout the
publication, an explanatory note on the cover sheet is sufficient.

provider or multiple providers. LE-4xx SCS devices are specifically designed to aggregate
subscribers, either directly connected using an SDS or an aggregation device such as another
device. The LE-4xx SCS incorporates advanced QoS capabilities, flexibility through pluggable
optics, superior multicast control, manageability, and a small form factor chassis to present the
industry’s leading fiber-to-the-building solution.
The 3xx SCS/SDS family of products include the LE-327 SCS that provide support for up to 24
subscriber connections via 100 Mbps SFP Ethernet ports. The LE-310 SDS supports up to 11
subscriber connections with a mix of 10/100/1000 Mbps ports. The LE-310 SDS provides support
for up to 4 uplink ports; 3 of which are dual speed 100BASE-FX/1000BASE-X SFP ports and a
fourth 10/100/1000BASE-TX port that can be used as an uplink port or a subscriber port. All
uplink ports can be active at a single time. Both LE-311 SDS and LE-311v SDS offer 24
10/100BASE-TX Ethernet ports.
Interconnectivity
CAUTION: Subscriber ports on all LE-3xx SCS/SDS and LE-4xx SCS devices are

The LE-4xx SCS uses public and private Simple Network Management Protocol (SNMP) MIBs for
switch management.
Public and private MIBs used with the LE-4xx SCS include:
• SNMP (RFC 1157)
• MIB-II (RFC 1213)
• Bridge MIB (RFC 1493)
• Ethernet MIB (RFC 1643)
• 4-group RMON (RFC 1757)
• IP Forwarding Table MIBs (RFC 2096)
• Multicast Routing MIBs
Device Manager
The LE-4xx SCS is managed directly using the Ciena/World Wide Packets Ethernet Services
Manager (ESM). The LE-4xx SCS can also be managed using any SNMP manager. Services can be
provisioned in real time without requiring software reloads or network outages. Alarms are also
managed using NMS. Refer to the LightningEdge Network Supervisor EMS and NMS manuals for
more information. The LE-4xx SCS can also be managed out-of-band via the local management
port.
DHCP/TFTP- Auto Configuration and Recovery
After system initialization, using Dynamic Host Configuration Protocol (DHCP), the LE-4xx SCS
can discover startup and configuration information, such as its IP address, gateway, and
command file name for downloading the application file via TFTP. This allows each device to be
configured automatically without user intervention. This dynamic configuration can also help in
recovering the device after a reboot or if a problem is detected.

RADIUS
Remote Authentication Dial-In User Service (RADIUS) protocol that authenticates dial-in users
and authorizes their access to the requested device or service. This type of authentication
provides added security, ensuring that only the authenticated administrator can access the LE-
4xx SCS for management configuration. Having a central location facilitates usage/billing
tracking and network statistics gathering.
Four-Group RMON
The LE-4xx SCS uses four-group RMON for management. These four groups include:
Statistics — provides performance information, packet size distribution, and error reports.
History — short term and long term statistics. History statistics can be configured by the user to
collect various statistics at user-definable intervals. These statistics can then be used to monitor
network performance.
Events — user-configured parameters that allow thresholds to be set that trigger alarms based
on current statistics.
Alarms — parameters in statistics can be configured to trigger alarms. Alarms, in turn, can
trigger SNMP traps or other elements.
VLAN Management
Provisioning and maintaining VLANs is fast and easy using the Device Manager. Each VLAN is
established with its own traffic rate and billing information to ensure that services are delivered
without noticeable jitter or delay. Valuable usage statistics are also collected. VLANs are
identified using 802.1Q tags.
As needed, each VLAN can carry multiple services or one single service. As a subscriber signs up
for a service, a VLAN is provisioned for the subscriber. Each service is carefully delivered to the
end device (set top box, PC, IP phone, etc.) complete with management functionality,
priorities, and counters. Packets from multiple service providers can be delivered to the same
subscriber without mixing traffic or complicated access control mechanisms. VLANs provide
security among neighbors of the same service or different services, as each subscriber can be
configured with a private VLAN to the service provider.
Prioritization
QoS entries can be created that give certain traffic a greater or lesser priority than it would
otherwise receive. Traffic can be classified based on the port a frame is received on and the
VLAN ID tag included in the frame, as well as the intended egress port. If a frame does not

INTERCONNECTIVITY
include tag information, the VLAN membership of the ingress port is used as the VLAN ID. If an
incoming traffic flow does not match any configured QoS entries, the flow is placed into a
default traffic queue based upon its egress port.
IGMP
Internet Gateway Management Protocol (IGMP) is used to support IP multicasting. Defined in RFC
1112, IGMP defines how hosts and routers within the same network establish membership in
multicast group streams. The use of IGMP allows the LE-4xx SCS to limit the broadcast of
multicast streams without user intervention.
Power and Redundancy
The LE-310 is only available as an AC-powered device. The LE-311, LE-311v, LE-327, and LE-427
feature hot-swappable power supplies. One power supply is required for normal operation while
a second power supply can be added for redundancy. These removable power supplies can be
ordered as either AC or DC devices.
Link Aggregation
This standard defines how two or more Ethernet connections can be combined to provide load
sharing, load balancing, and provide better reliability for high-traffic network connections.
The standard also provides inherent, automatic redundancy on point-to-point links. This is
accomplished by dynamically redirecting traffic from a failed port (in a multi-port application)
across the remaining good ports in the link.
