Nways Manager for AIX-LAN Network Manager/I.H.M.P. User's Guide

Coupling and Navigating Between Campus Managers - LAN and ATM

Nways Manager-LAN and Nways Manager-ATM can be coupled to provide full management of ATM modules in 8260 hubs and 8265 ATM switches. Coupling involves integrating the topologies and device status used by each product.

Nways Manager-LAN and Nways Manager-ATM can be coupled in the following ways:

• 8250, 8260, and 8265 Device Manager can be coupled with Nways Manager-ATM.

• LAN Network Manager can be coupled with LAN Emulation Manager.

Coupling 8250, 8260, and 8265 Device Manager and Nways Manager-ATM

Starting Coupling

The coupling between the 8250, 8260, and 8265 Device Manager application in Nways Manager-LAN and Nways Manager-ATM is started automatically when you start Nways Manager-LAN.

To change this default setting using SMIT, follow these steps:

1. From NetView for AIX, select Administer -> Campus Manager SMIT -> Control -> Coupling with Nways Manager-ATM.

2. Click on the List button and select one of the values displayed:

   • Start (default)

   • Re-Sync

   • No

   • Status

For more information on configuring Nways Manager-ATM, refer to the online documentation, Nways Manager-ATM for AIX User's Guide.

Stopping Coupling

To stop the coupling between 8250, 8260, and 8265 Device Manager and Nways Manager-ATM, follow these steps:

1. From NetView for AIX, select Administer -> Campus Manager SMIT -> Control -> Coupling with Nways Manager-ATM.

2. Set the value for Nways Manager-ATM Coupling to No.

This stops the integration of the two topologies and removes the Nways Manager-ATM options from the menus displayed for the ATM and Switch modules in graphical views of 8260 hubs and 8265 ATM switches.

Resynchronizing Coupling

If ATM and Switch modules remain blue in Hub Level views, you may need to resynchronize the coupling between 8250, 8260, and 8265 Device Manager and Nways Manager-ATM. This can occur if many changes are made to the network since the two topologies were coupled.

To resynchronize the two topologies:

1. From NetView for AIX, select Administer -> Campus Manager SMIT -> Control -> Coupling with Nways Manager-ATM.

2. Set the value for Nways Manager-ATM Coupling to Re-sync.

Displaying Coupling Status

To display the current status of the coupling between 8250, 8260, and 8265 Device Manager and Nways Manager-ATM, select Administer -> HubManager -> Administration and do one of the following:

• Select Control -> Coupling with Nways Manager-ATM and set the value for Nways Manager-ATM Coupling to Status.

• Select Administer -> Campus Manager SMIT and set the value for Nways Manager-ATM Coupling toStatus. .

Port Status

Table 36 shows how the status of LAN ports displayed on the Port Configuration panel corresponds to the operational state of ATM interfaces displayed in the ATM Interface Configuration panel in Nways Manager-ATM.

Table 36. Status of LAN Ports and Operational State of ATM Interfaces

Status of LAN Ports (Nways Manager-LAN)	Operational State of ATM Interfaces (Nways Manager-ATM)
unknownStatus	unknown
off	disabled-nosignal
off	disabled-idle
noPhantom	nosignal
noPhantom	idle
fatalError	idle
okay	in-service
okay	pvcOnly
fatalError	failing
fatalError	misConfigured
fatalError	wrong-network-prefix
fatalError	wrong-node-number

Module Status

The color-coded status of module icons in Hub Level views is an aggregate of the status of the module and the status of ports on the module. Because the status of modules is always reported as unknown, the color of the module icon is an aggregate of the status of its ports.

Coupling LAN Network Manager with LAN Emulation Manager

When you install both LAN Network Manager and LAN Emulation Manager, the two applications are automatically coupled. This coupling allows realtime, color-coded status of ATM/LAN bridges and switches to be displayed in LAN Subnet submaps.

ATM Management

In standalone mode, Nways Manager-LAN provides a subset of the management functions for ATM modules (Switch and media) installed in an 8260 Hub or 8265 ATM switch.

The coupling of Nways Manager-LAN and Nways Manager-ATM provides comprehensive management of hubs, legacy LANs, and ATM networks that allows you to:

• Start Nways Manager-LAN from Nways Manager-ATM by selecting an 8260 or 8265 icon.

• Display graphical color-coded information in Module Level views in Nways Manager-LAN about the status of ATM devices based on information received from Nways Manager-ATM.

Navigating Between Campus Managers - LAN and ATM

To navigate between Nways Manager-LAN views and Nways Manager-ATM submaps, do one of the following:

• From a Hub Level view, double-click on the icon of an ATM Switch or media module.

• From a Module Level view, double-click on an ATM device or select Explode from the context menu of an ATM device.

To navigate between Nways Manager-ATM submaps and Nways Manager-LAN views, do one of the following:

• From an ATM Cluster submap, select CMA -> Device from the context menu of an ATM Switch or device or select an ATM Switch (or device) and then select CMA -> Device from the menu bar.

• From an ATM Node submap, select Device from the context menu of an ATM Switch or device.

• From the ATM Switch Configuration panel, select Navigation -> Device from the menu bar.

Navigating with LAN Emulation Manager
