Synopsis islshow
Description Use this command to display the current connections and status of the interswitch link (ISL) for
each port on a switch. The command output includes the following information:

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:-------".
Note The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may
be in place. Refer to chapter 1, "Using Fabric OS commands" and Appendix A, "Command
Availability" for details.
