EMC Connectrix DS-32B2 and ED-12000B Fabric OS Reference Manual
Telnet Commands
The connections between pairs of M-to-M ports are chosen to
exercise the connections between as many ASICs as possible
subject to the availability of pairs of M-to-M ports.
◆ In mode 1 with SPLB mode disabled, the spinsilk command
only circulates frames within each single port and none of the
ASIC-to-ASIC connections are tested. This mode should only be
used for fault isolation.
◆ 2 for external loopback mode. The external loopback test creates a
test loop between two ports on different ASICs and also tests the
Serializer Deserializer functionality.
◆ 5 for internal loopback mode. The internal loopback test creates a
test loop between two ports on a single ASIC.
Refer to the
setSplbmode command for more information on how the
loopback mode setting changes the execution of this command.
SFP/GBIC Mode If the
spinSilk command is executed with GBIC mode activated,
only ports containing GBICs are tested. To activate GBIC mode,
execute the following command prior to executing the
spinSilk
command:
switch:admin> setGbicMode 1
The state of the GBIC mode is saved in flash and remains active over
a reboot until it is disabled as follows:
switch:admin> setGbicMode 0
Prior to running this command make sure you disable the switch, set
the GBIC mode to 1, and install loopback cables on all GBIC ports
you want to test.
Because this test includes the GBIC and the fiber cable in its test path,
use the results from this test in conjunction with the results from
crossPortTest and portLoopbackTest to determine those switch
components are not functioning properly.
