IBM manual Configuring Port Redundancy for 8260 Ethernet Modules

Note

Using DIP switches on the 8260 Ethernet 10-Port 10Base-FB Module, it is only possible to assign all the ports to the same network. This network can be one of the 8 Ethernet segments on the backplane, or isolated-1.

∙Enable/disable ports

Each port on the 8260 Ethernet 10-Port 10Base-FB Module can be enabled/disabled independently from the other ports. You can use the following management module command to enable/disable a port:

SET PORT {slot.port} MODE {enabledisable}

∙Set port redundancy

The port redundancy feature allows you to set redundancy between two ports. The two ports can be on the same or different modules and can be of different types. For example, a 10Base-T port can be defined to be a redundant port for a 10Base-FB port. Also, port redundancy is allowed between the 8250 and the 8260 ports. You can use the following management module command to set port redundancy:

SET PORT {slot.port} MODE REDUNDANT {slot.port}

When configuring port redundancy, the redundancy should be enabled for one end of the link only. This is shown in Figure 76.

Figure 76. Configuring Port Redundancy for 8260 Ethernet Modules

When port redundancy is no longer required, you can use the following management command to set the port to operate in non-redundant mode:

SET PORT {slot.port} MODE NON-REDUNDANT

∙Enable/disable port alert

You may use the following command to enable/disable the port up and down alerts received from the individual ports on this module:

SET PORT {slot.port} ALERT_FILTER {enabledisable}
