spinSilk spinSilk Functional test of port connection at maximum switch speed. Synopsis: V3.1.x spinSilk [nmillionframes[, sfpmode[, lbmode[, spdmode]]]] Synopsis: V4.1.x spinSilk [-nmegs count][-gbic_mode mode][-lb_mode mode] [-spd_mode mode][-verbose mode][-ports itemlist] Availability Admin Release V3.1.x and V4.1.x Description This command verifies the functional operation of the switch by setting up the routing hardware such that frames received by port M are retransmitted through port N. Likewise frames received by port N are retransmitted through port M. Each port M sends 1 frame to its partner port N through an external fiber cable, exercising all the switch components. Note: The spinsilk command may not be executed on an operational switch. You must first disable the switch using the switchDisable command. The cables can be connected to any port combination with the condition that the cables and SFPs connected are of the same technology. For example, a short wavelength SFP port must be connected to another short wavelength SFP port through a short wavelength cable; or a long wavelength port must be connected to another long wavelength port.
