Changing Expand Line-Handler Process Modifiers

You can use the WAN subsystem SCF ALTER DEVICE command to change any

modifier or modifier value in the device record for a specific Expand line-handler

process.

You can use the Expand subsystem SCF ALTER LINE and ALTER PATH commands to

change certain Expand line-handler process modifiers and modifier values. Modifiers

that can be changed using the Expand SCF commands are listed in Section 17,

Expand Modifiers.

Changing Profiles

You cannot alter a profile directly (there is no ALTER PROFILE command). However,

you can alter a modifier in a profile indirectly by deleting and reading the profile or by

using the ADD PROFILE command with the LIKE option.

For more information about profiles, refer to the WAN Subsystem Configuration and

Management Manual.

Adding Nodes to the Network

This subsection explains how to add a new node (system) to the network using the

management commands described in the preceding subsections. This explanation is

presented in three steps.

Step 1: Create and start Expand line-handler processes at

adjacent nodes

Using the WAN subsystem SCF ADD DEVICE and START DEVICE commands, you

must create and then start an Expand line-handler process at the new node for each

link to an adjacent (or neighbor) node. You must also create and start an Expand line-

handler process at each adjacent system for the link to the new system.

Note. Certain Expand profile modifiers do not have corresponding attribute names in Expand

SCF and therefore can be changed only by using the SCF interface to the WAN subsystem. In

addition, certain Expand SCF attributes do not correspond to Expand profile modifiers and

therefore can be changed only by using the SCF interface to the Expand subsystem. These

modifiers and attributes are listed in Section 17, Expand Modifiers

Note. When you use the ALTER DEVICE command to change a modifier or modifier value for

a specific device, you are changing the device record for that device, not the profile used by

that device. Modifiers and modifier values that are part of a device record can be different from

the modifiers and modifiers values in the profile used by a device.
