hi,
I have the following:
1-IBM mainframe:
----------------------
- has two OSA cards (with FDDI ports)
- Each OSA has two IP address's one for TEST and one for Production
- The two OSA have different MAC address.(user defined MAC)
2- two Ciso 5505:
------------------------
-Each switch has FDDI module
The old setup:
-------------------
Before,I have 2 old hubs (not cisco) connecting to the two OSA through token ring,the mainframe OSAs are configured now for this setup.
The new setup (which I want to make)
----------------------------------------------------
to connect the two 5505 to the two OSA by FDDI ,in this case I'll get two dual ring ,one for each OSA.
I would like to know what is the correct connection between them?
Do I need to add additional configuration between the two OSA on the mainframe (since now I'll have Dual ring not single ring)?
please I need any information about this problem.
