spinSilk GBIC/SFP Mode (sfpmode): V4.1.x 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> setsfpmode 1 The state of the SFP mode is saved in non-volatile memory and remains active over a reboot until it is disabled as follows: switch:admin> setsfpmode 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 GBICs and the fiber cable in its test path, use the results from this test in conjunction with the results from crossporttest and portloopbacktest can be used to determine those switch components that are not functioning properly. Operands This command has the following operands: nmillionframes (V3.1.x only) sfpmode (V3.1.x only) lbmode (V3.1.x only) spdmode (V3.1.x only) Specify a number of times, representing a million frames per port, to execute this test. If omitted, the default value used is 0xfffffffe (or almost infinite for practical purposes) as passcount. Specify 1 to enable SFP mode for the test. The SFP mode parameter may be used to override the global SFP mode setting for the duration of this test. When it is enabled, testing is limited to user ports with SFPs installed. Specify the loopback mode for the test. Valid values are: 0 cabled loopback Port MN only (default) 1 cabled loopback Port M->M & MN allowed 3 external silkscreen loopback (no retry) Any other value selects internal loopback. Specify the speed at which the test is run: 0 set port speed for auto-negotiate. 1 set port speed to lock at 1 Gbit/sec. 2 set port speed to lock at 2 Gbit/sec.
