When issued on a switch that is part of a logical fabric configuration, the islShow command displays
logical interswitch links (LISLs) along with regular ISLs. However, speed (sp) displays N/A for logical
ports. The bandwidth (bw) displayed is the sum of the bandwidth of all extended ISLs (XISLs) that form
the LISL. A shared ISL (XISL) connects the base switches and is shared by different logical fabrics. It
allows devices to communicate with each other within the logical fabric.
Connection speed is not applicable to LE_Ports or VE_Ports. For these port types, speed displays as
"sp:-------".
NOTES
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
