ATM Uplink Module Overview
The ATM (Asynchronous Transfer Mode) Uplink module provides
LAN Emulation (LANE) or RFC 1483 connectivity over anAT
network. The module comes in four variants:
■2-port SONET (Synchronous Optical NETwork)/SDH
(Synchronous Digital Hierarchy) OC-3c/STM-1 SMF (Single
Mode Fiber)
■2-port SONET/SDH OC-3c/STM-1 MMF (MultiMode Fiber)
■2-port SONET/SDH OC-12c/STM-4c SMF
■2-port SONET/SDH OC-12c/STM-4c MMF
Each module has multiple physical interfaces capable of being
simultaneously active.
Table 1-1 lists the modules wavelengths.
Table 1-1. Wavelength
The major features of theATM Uplink module are:
■LANE V2 Client - with LANE 1 compatibility, supports up to
128 switch ports
■QoS (Quality of Service) support for Unspecified Bit Rate
(UBR), non real-timeVariable Bit Rate (nrt-VBR), real-time
Variable Bit Rate (rt-VBR), and Constant Bit Rate (CBR)

Communications Overview
Ethernet attached devices communicate across anATM network
using LANE or RFC 1483. The Cajun ATM Uplink module supports
LANE V2 clients enabling interoperability with LANE V1 networks.
Each CajunATM Uplink module has multiple physical ports. Each of
these ports can connect to any network node of anATM cloud.
Depending on configuration, the links act as primary and backup
links, or connections are load shared across all of the ports.
LANE
The basic function of the LANE protocol is to simulate a
connectionless LAN service over a connection-oriented ATM
network. There are four basic components of LANE:
■LEC (LAN Emulation Client) - An entity in an end system
that performs data forwarding, address resolution, and other
control functions. A LEC also provides a standard LAN
service interface to any higher-layer entity that interfaces to
the LEC. Each LEC is identified by a uniqueATM address,
and is associated with one or more Media Access Control
(MAC) addresses reachable through that ATM address.

Cajun P550/P880 Switch ATM Uplink User Guide, Version 1.1
Overview
1-3
■LECS (LAN Emulation Configuration Server) - An entity
that assigns individual LANE clients to particular Emulated
LANs (ELANs) by directing them to the LAN Emulation
Server (LES) that corresponds to the ELAN. There is logically
one LECS per administrative domain, and this serves all
ELANs within that domain.
■LES (LAN Emulation Server) - An entity that implements
the control function for a particular ELAN. There is only one
logical LES per ELAN, and it is identified by a unique AT
address.
■BUS (Broadcast and Unknown Server) - Multicast server
used in ELANs to flood traffic addressed to an unknown
destination and to forward multicast and broadcast traffic to
the appropriate clients.
The basic concepts are consistent between LANE V1 and LANE V2,
however there are some differences between them. The main
difference is that LANE V2 provides QoS support and multiplexing
of Virtual Circuits (VCs).
LANE is one of the mechanism theATM Uplink module uses to
simulate a LAN over theATM network. By implementing a LANE
client in the ATM Uplink module, the ATM network can seamlessly
provide connectionless LAN and multicast capabilities to the rest of
the Cajun system.
The logical topology of the ATM Uplink module interfaces is quite
different from the physical connections. LECs are configured on the
ATM Uplink module. A LEC is not associated with a physical port,
but instead is associated with a LANE server that forms an ELAN.
A LEC is treated similarly to an Ethernet port of the Cajun system
and is associated with a Virtual LAN (VLAN). A LEC is represented
and configured as a switch port in the Cajun system. Each VLAN
may have only one LEC per ATM Uplink module, and each module
may have only one LEC per ELAN.

1-4
Chapter 1
Cajun P550/P880 Switch ATM Uplink User Guide, Version 1.1
RFC 1483
RFC 1483 defines an encapsulation method for transporting
multiple protocols over the same or different VCs using the ATM
Adaptation Layer 5 (AAL5) protocol. Implementation is limited to
Permanent Virtual Circuits (PVCs). The ATM Uplink module
supports 802.3 Ethernet, as well as a routed Protocol Data Unit
(PDU) for layer 3.
The ATM Uplink module supports up to128 Virtual Switch Ports
(VSPs) and LECs per module. A VSP is a single port on the Cajun
P550/P880 switch. It appears as a switch port to the supervisor
module and is bound to a VLAN by the supervisor. Only one VSP
may be bound to a particular VLAN.
* Notes:
■You need alicense key in order to use RFC 1483. Refer to the
Cajun P550/P880 Switch ATM Uplink Installation Sheet for more
information on the license key.
■You can configure a module with both LANE and RFC 1483,
if you have purchased a RFC 1483 license key
Quality of Service
QoS (Quality of Service) is a measure of guarantee performance for
the transmission quality and service availability of a transmission
system.
QoS is implemented in LANE through configuring sets ofATM
traffic parameters (QoS Sets) and associating these with the different
Ethernet frame priorities (0 - 7). A Data Direct Virtual Channel
Connection (DDVCC) is setup to a QoS capable LEC for each QoS set
as needed.

Cajun P550/P880 Switch ATM Uplink User Guide, Version 1.1
Overview
1-5
A QoS domain is a set of rules for mapping between frame priorities
and ATM QoS Sets. A QoS Domain also consists of a series of QoS
Sets and their priority mappings. A QoS Set is a set of signaling
parameters that describe a traffic class.
In an RFC 1483 environment, each PVC has its own QoS
parameters.Traffic priority to channel mapping is done through a
link that groups up to eight channels to a common ATM end point.
UNI Signaling
User-to-Network Interface Signaling (UNI) dynamically creates and
removes Switched Virtual Connections (SVCs) in an ATM network.
The higher layer ATM protocols, specifically LANE, use the UNI
signaling for connectivity.
ILMI 4.0
The Integrated Local Management Interface (ILMI) protocol
provides the ATM Uplink module with status and configuration
information across the user-to-network interface. This information
includes ATM network prefixes, registered services, and capabilities.
PNNI
Private Network-to-Network Interface (PNNI) is a dynamic routing
protocol that manages and allocates network resources for SVCs in
an ATM network. Because the ATM Uplink module implements
PNNI in non-transit mode, theATM Uplink module does not act as
an intermediate ATM switch in an ATM network. This provides
high-performance edge access and load-sharing.
PNNI provides the ability to distribute topology information
throughout the network. The ATM Uplink module is capable of
having multiple active links, so PNNI is used to make routing
selections to optimize link utilization and provide load sharing.
When aconnection with specific QoS parameters is requested, PNNI
is able to dynamically find a possible path (if any) satisfying the
request, allocate the necessary resources in the network, and
provision the connection.
PNNI enables the network to respond quickly to link failures, link
recoveries, and changing network loads on any link. The network is
able to adapt to changes in the addressing of a network or the
topology of the network as switches are added or deleted.

Link Failover
* Note: This feature applies to LANE only.
In networks that do not support PNNI, you can use link failover as
an alternative to multiple active interfaces. With this feature, one
link is active with all other links designated as standby. If one link
loses its connectivity, a standby link becomes active and the
connections are re-established. Links are weighted to determine
which link attempts to take over first.
Spanning Tree
The SpanningTree protocol is used toprevent loops from forming in
your network. The spanning tree algorithm creates a single path
through the network by ensuring that if more than one path exists
between two parts of a network, only one of these paths is used,
while the others are blocked. Because of the number of “bridges”
present in a switched networking environment, spanning tree
structures can become extremely complex. The ATM Uplink module
supports the spanning tree per VLAN option (each LEC has an
independent STP state).
* Note: The current version of theATM Uplink module supports
only the spanning tree per VLAN option.Each VLAN
runs a separate spanning tree with its own Bridge
Protocol Data Units (BPDUs). This allows each LEC to
have a spanning tree state that is independent of the
otherLECs on its module and does not supportspanning
tree on RFC 1483 connections.
For more information on spanning tree support and configuration,
refer to the Cajun P550R/P880/P882 Switch User Guide.
