IBM 8260 manual SET Port slot.port Mode enabledisable, SET Port slot.port Mode Redundant slot.port

Each port on the 8260 Ethernet 24-Port 10Base-T 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 set redundancy between two ports. The two ports can be on the same or different modules and can be of the same or different types. For example, a 10Base-T port can be defined to be a redundant port for a 10Base-FB port. 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 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 auto-polarity

This feature enables the 8260 Ethernet 24-Port 10Base-T Module to automatically switch the polarity of the twisted-pair cabling in case the polarity of the cabling has been erroneously reversed during the cable assembly. To enable auto polarity detection and reversal on each port, you can use the following management module command:

SET PORT {slot.port} AUTO_POLARITY {enabledisable}

∙Enable/disable link integrity

To connect older equipment, that does not fully comply with the 10Base-T standard, to this module, you may have use the following management module command to disable the link integrity:

SET PORT {slot.port} LINK_INTEGRITY {enabledisable}

∙Enable/disable port alert

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

SET PORT {slot.port} ALERT_FILTER {enabledisable}

This command may be used to allow you to monitor the status of the crucial ports on your network while the alerts from the other ports are disabled.

∙Enable/disable remote diagnostics

The Remote Diagnostics feature allows this module to detect certain unusual failure conditions when used in conjunction with the IBM Fault-Tolerant 10Base-T Transceivers. You can use the following management command to enable/disable remote diagnostics:

SET PORT {slot.port} MODE {remote_diagnosticsnon_remote_diagnostics}

Note

The 10Base-T specification specifies a minimum of 31 collisions prior to partitioning of a port. The 8260 Ethernet 24-Port 10Base-T Module automatically partitions a port when more than 63 collisions are detected on that port. This value cannot be changed by the users.
