Fabric OS Commands
166 Fabric OS Version 3.1.x/4.1.x Reference Guide
V3.1.x: SFP Mode
Use the setgbicmode command (setGBICMode) to activate SFP mode by
executing the following command prior to executing the crossPortTest
command:
switch:admin> setgbicmode 1
When activated, only ports with SFPs present are tested by the
crossporttest command. For example, if only port 0 and port 3 contain
SFPs and the SFP mode is activated, the crossporttest command limits
testing to port 0 and 3.
The state of SFP mode is saved in non-volatile memory and remains active after
reboots or power cycles until it is disabled as follows:
switch:admin> setSFPMode 0
V4.1.x: SFP Mode
Use the setafpmode command (setsfpmode) to activate SFP mode by
executing the following command prior to executing the crossPortTest
command:
switch:admin> setsfpmode 1
When activated, only ports with SFPs present are tested by the
crossporttest command. For example, if only port 0 and port 3 contain
SFPs and the SFP mode is activated, the crossporttest command limits
testing to port 0 and 3.
The state of SFP mode is saved in non-volatile memory and remains active after
reboots or power cycles until it is disabled as follows:
switch:admin> setsfpmode 0
V4.1.x: Example Operation
An example mode of operation would be to disable the switch, set the GBIC mode
to 1, and execute crossporttest with -lb_mode 1 activated and the
crossporttest would then limit its testing to:
■ Only ports which are stuffed with media, and
■ Ports with media which are properly cable looped back, and
■ Ports are allowed to be connected to itself (single port connections).
