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 {enable|disable}
•
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 {enable|disable}
•
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 {enable|disable}
•
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 {enable|disable}
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_diagnostics|non_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.
