Module Speciﬁc Information

Introduction

This appendix contains local management information that is speciﬁc to the

following ATM Modules:

• 9A128-01 (1 Port, Multimode Fiber, SC Connector)

• 9A129-01 (1 Port, Single-Mode Fiber, SC Connector)

Module Interfaces

The 9A128-01 and 9A129-01 ATM Modules have four interfaces. Table 1 lists the

identifying number, name, and description of each interface.

Use the numbers listed in Table 1 to conﬁgure the module’s default interface (see

the General Conﬁguration Screen).

FNB Resource Conﬁguration Codes

The 9A128-01 and 9A129-01 ATM Modules provide connectivity between two

interfaces: the front panel interface and one of the FDDI rings on the backplane

(FNB-1 or FNB-2).

The FNB Resource Conﬁguration Screen allows you to connect the module’s front

panel interface to one of the chassis’ two FDDI networks (FNB-1 or FNB-2) via a

bridge/router.

The FNB Resource Conﬁguration Screen lists all the possible connections that the

module can support on the FNB, displays the current connection, and allows you

to change the connection. Table 2 lists and describes the FDDI connections from

which you can select.

9A128-01 and 9A129-01 Module Speciﬁc Information

Virtual Channels and Virtual Paths

Rather than addressing cells to a speciﬁc destination, as in a LAN, ATM addresses

cells to Virtual Channels (VCs) and/or Virtual Paths (VPs). This addressing takes

place in the header ﬁeld of the ATM cell.

VCs and VPs are bi-directional (i.e., they transfer information in both directions

on a single channel or path), and are “set up” between devices on the ATM

network prior to transmission. Similar to WAN transmission, ATM technology

provides the ability to send several VCs together over a VP, and several VPs over

an ATM link segment.

Permanent and Switched Virtual Channels

ATM networks use two different types of Virtual Channels – Permanent Virtual

Channels (PVCs) and Switched Virtual Channels (SVCs). The difference between

PVCs and SVCs exists in the channel setup.

PVCs are pre-conﬁgured by an administration function, and are usually

established for long term use. After setting up this channel, nothing else is

required by the network to transfer information between the two established

points. This type of virtual channelling is established through a local or remote

management interface.

SVCs use a signaling and network switching procedure to set up dynamically. In

other words, SVCs are established “on the ﬂy,” as needed for a particular service,

used to transmit on the short term, and then terminated.

ATM Connection Setup Screen Fields

The following information brieﬂy explains each ATM Connection Setup Screen

ﬁeld.

ATM Port

Displays the MIB II interface number. Valid values are 4 through 67.

Current Connections

Displays the number of connections (PVCs and SVCs) conﬁgured to the module.

VPI

Displays the Virtual Path Identiﬁer (VPI) of each connection. You assign VPIs in

the Add/Delete Entry screen.

VCI

Displays the Virtual Channel Identiﬁer (VCI) of each connection. You assign VCIs

in the Add/Delete Entry screen.

Encapsulation Type

Displays the method used to encapsulate data at the ATM Adaptation Layer 5

(AAL-5) for each connection. The 9A128-01/9A129-01 module supports the

following methods of encapsulation:

•

VC Mux 802.3 LANE (default)

VC Based Multiplexed 802.3 LAN Emulation. This method is speciﬁed by the

ATM Forum LAN Emulation speciﬁcation.

•

VC Mux Bridged 802.3

VC Based Multiplexing for bridged protocols as deﬁned by the IETF

RFC 1483.

•

LLC Encapsulation

AAL Type

Displays the ATM Adaptation Layer (AAL) type of each connection. The AAL

divides the user information into segments suitable for packaging into series of

ATM cells. The ATM Forum’s LAN Emulation speciﬁcation dictates that AAL-5

be used for all LAN emulation trafﬁc. The 9A128-01/9A129-01 module supports:

LEC Administration Screen Fields

The following information brieﬂy explains each LEC Administration Screen ﬁeld.

LEC Index

Displays the MIB II interface number. Valid values are 4 through 67.

Conﬁgure ELAN (Toggle)

Speciﬁes whether the LAN Emulation Client should auto-conﬁgure. Use the

Space Bar to select one of the following choices:

• Automatic (default) - A client uses a LAN Emulation Conﬁguration Server

(LECS) to learn the ATM address of its LAN Emulation Server and to obtain

other parameters.

• Manually - The ATM address of the LAN Emulation Server (LES) and the

values of other parameters must be entered by the user.

ELAN Name

The name of the ELAN to which this client is joined.

By default, the unit makes a LANE join request to the ATM network with the

ELAN name blank (no entry). By popular LANE convention, Join Requests of this

type will put that client into the ﬁrst conﬁgured ELAN on the LECS (also known

as the “default ELAN”). Assume this ELAN is named “ELAN1”. Once the device

has successfully completed the Join process, all ATM-speciﬁc Local Management

screens will then reﬂect “ELAN: ELAN1”. This means that all Local Management

screen information pertains to the “ELAN1” ELAN.

To set the device back to join the “default” ELAN, you must delete the current

ELAN (ELAN1). After the current ELAN is deleted, a message is displayed that

states that there are no longer any active ELANs. Now, you can move to the

ELAN Name ﬁeld. Press the Space Bar and then the Return key. Highlight SAVE

and press the Return key. This will cause the device to join the “default ELAN”

again.

Since we support just a single ELAN, you cannot create a new ELAN unless all

current ELANs have been deleted.

If there are currently no active ELANs, then all choices on the ATM Speciﬁc

Conﬁguration Screen will result in the message “No ACTIVE ELAN present”. You

can only access the Connection Table screen and the LEC Administration screen.

You cannot access the LEC Properties screen, since there is no information.

Future releases will support multiple ELANs. Check your release notes to

determine whether your release supports multiple ELANs.

NOTE

9A128-01 and 9A129-01 Module Speciﬁc Information

Max MTU Size (Toggle)

the Initial State. Use the Space Bar to select one of the following choices:

• 1516 (default)

• 4544

LAN Type (Toggle)

The data frame format this LEC is using currently. Use the Space Bar to select one

of the following choices:

• 802.3 (default)

• 802.5

LES ATM Address

The LES this client will use the next time it is started in manual conﬁguration

mode.

Adding an ELAN

To add an ELAN:

1. Use the arrow keys to highlight the Conﬁgure ELAN ﬁeld.

2. Press the Space Bar to select either Automatic or Manually.

3. Use the arrow keys to move to the ELAN Name ﬁeld.

4. Type the name of the ELAN you want to add.

5. Use the arrow keys to move to the Max MTU Size and LAN Type ﬁelds. Using

the Space Bar, select the appropriate choice for each ﬁeld.

6. Use the arrow keys to highlight ADD/MODIFY, then press the Return key.

The message “ADD COMPLETE” is displayed.

Remember, since we support just a single ELAN, you cannot create a new ELAN

unless all current ELANs have been deleted.
