Is there a clear how-to documentation for ISL-ing two Brocade 5100's? Should be relativly easy, however I couldn't find it in "Fabric OS Administrator’s Guide" ..
Brocade 5100, all ports enabled are F-Ports,
zoning: ON (luns)
FC Router: OFF
Fabric Name: prod_san
Allow XISL Use: OFF
I've a got another Brocade 5100 which I need to hookup to the existing switch and extend an existing fabric.
Can I use just a random spare port for ISL?
Are there requirements for ISL path-cord? like length limit etc? I plan to use 8GB ISL.

1) Trunking is not required and not mandatory
2) ISL Basic config is very simple.
make sure each switch in the fabric have a unique Domain ID i.e. SWITCH_1 Domain ID 1 and SWITCH_2 Domain ID 2
now connect SW1 with SW2 and you have ISL Configured, nothing expecially is required.

Thanks, the document is helpful as well.
ISL topic seems to be hot, I'd assume many users would appreciate it if Brocade could release "white paper" for that.
I'll try to ISL my switches next week and update the thread with results.

As mentioned, in order to Formed ISL, you need just a couple of simple Basic Config.
FOS Admin Guide and Command Reference Manuals, are excellent basically DOC to understand and build a simple Fabric.
As far as i remember ISL WP was available many years ago any new is unknown to me.
I'll try to find some other DOC about ISL, if I find one I'll upload here.

Here are the commands I executed to to create ISL:
// switch_01 - the existing switch
// switch_02 - the new switch
1. switch_02> switchdisable
2. switch_02> configure
// set domain_id here, it was 1 in my case
3. connect inter switch link
3.5 Set switch_02 default zone policy to "All access":
switch_02> defzone --allaccess
4. switch_02> switchenable
The switches do everything else automatically.
5. check ports status on the switches, both should be E_port:
switch_01 additional port info - "downstream"
switch_02 additional port info - "upstream"

Do we have to disable the switch to add 1 port to existing ISL to down stream ?
We have port 3 going to down stream switch which is ISL - 8GB , we need to change the cable to test so we were trying to add port 4 to the same trunk and remove cable from port 3 to test ? So we will not loose any connectivity.
