HP UX Auto Port Aggregation (APA) Software manual Interoperability with HP Serviceguard

•The same link aggregate or failover group can offer different level of service for each user using ToS. You gain more flexibility in how you deploy link aggregates and failover groups.

•You can create, remove, and modify VLANs over link aggregates and failover groups without rebooting the system. This enables you to configure networking on a server without disrupting other users.

For more information on managing and using VLANs, see HP-UX VLAN Administrator's Guide and your switch documentation.

Appendix D (page 113) describes characteristics of using VLANs over link aggregates and failover groups and guidelines for each configuration.

Administrative Methods

The following sections provide a brief overview of the methods for administering HP APA. HP recommends that you use the System Administration Manager (SAM) whenever possible.

HP System Administration Manager

The HP System Administration Manager (SAM) enables you to administer your HP-UX system locally via a graphical user interface (GUI) and terminal user interface (TUI). SAM produces fewer errors and saves your configuration data permanently so configuration does not require a reboot to take effect. It is the recommended method for configuring link aggregates.

NOTE: You cannot use SAM to configure failover groups. For more information, see “Editing Configuration Files for Failover Groups” (page 107) and “Configuring VLANs over Failover Groups” (page 114).

In this manual, wherever SAM is mentioned in relation to HP APA configuration tasks, it is presumed that you know how to invoke it.

For more information about the System Administration Manager, see sam(1M) and the online help.
