How to setup inter-switch link? I noticed that there are inter-switch link already configured for some port(s) on each sw5k switch here with core switch sw48k. I am wondering how that was initially setup?

Thanks David, is it the case that when the 2 F-ports from 2 different switches got connected, these 2 F-ports will be automatically turned into E-ports?

The short answer is NO. In a Fabric Switched network, there is a two-way connection between an N-Port and the F_Port. N_Port stands for Node Port and located at the termination (Node) end. F_Port stands for Fabric Port and is located at the switch end. E_port is only used for ISL connection.
Hope this helps.

Per help page from portcfgeport, E_Port is enabled by default.
Could I say that, unless the port is explicitly disabled via 'portcfgeport slotnumber/portnumber, 1), when I connected 2 ports from 2 different switches, these 2 ports will be automatically turned into E_Port? And if I disabled using 'portcfgeport slotnumber/portnumber, 0', it would be an F_Port?
Or is there any other steps need to be done here?

Yes, unless you explicitly restrict it becomes an E-port, the 2 switches will automatically merge, provided there's no conflict, such as domain ids and the ports will automatically become E-ports. But if you decide not to allow the port to talk as E-port, then it will become one of the other the types but not E-port, such as F, FL
Nothing else need to be done. It's very much it.
