The biggest trunk can contain 8 ISLs on 8Gbit platforms.
Within one octet you can have 4 trunks of each two ISL as well.
So within one Octet 1-4 tunks are possible.
The number if Ocetet depends on the switch or blade model.

trunking is enable by default and configured/formed out itself as soon, when TWO or more ISL cable are connected between two switch.
You can configure / formed more trunk, theoretically so many as you have port free.
In Example if you have a DCX with 8x 48 Port Blade total of 384 Port, you can formed Total 192 trunk each with 2 Port.
