I want to find information about using Ethernet interfaces in ISG-2000 as link aggregation bundles.
Refer to Juniper ScreenOS Reference Guide, ISG-2000 supports this feature only for SPM modules and does not support that feature for I/O modules.
I tried to find any SPM modules for ISG-2000, but only I/O modules presents inside Juniper price-list.
Please help me to find Ethernet modules for ISG-2000 which supports aggregating.

Where did you read that link aggregation is not supported on the ISG2k I/O modules (link, page no.)? All in-band interfaces on the ISG2k come from I/O modules, there are no built-in in-band interfaces on it. Link aggregation is supported and possible on the ISG2k.

In the document "ScreenOS Concepts & Examples Reference Guide" in the part 11 "High Availibility" (http://www.juniper.net/techpubs/software/screenos/
Some system platforms, such as the Integrated Security Gateway (ISG) systems and the NetScreen-5000 systems, allow you to combine the throughput of one or morepairs of physical ports into a single virtual port. This virtual port is known as an aggregate interface. Only Secure Port Modules (SPMs) support this feature, and you can only aggregate side-by-side ports that reside on the same module.
NOTE: Aggregation is not allowed across I/O modules
So this is the reason why I asking you, technical community, where the truth?

Aggregate ports cannot be configured across I/O modules, but they can certainly be configured using ports within an I/O module.

Ok, thank you!
Now I got what the point inside this note.
But why there is a sentence "Only Secure Port Modules (SPMs) support this feature"? Is an I/O modules are SPM modules also?

SPM are the interface cards used on NS5200/5400 devices. The other type of card for these devices are Management modules, which have a few built-in interfaces for OOB and HA. So it is not relevant for ISG's. All the I/O modules for ISG's support aggregate interfaces.
