I'm trying to upgrade IOS in Dual MSFC3 routing cards, currently I'm running IOS Version 12.2(17a)SX1 (quite old) and cisco sent me a document outlining step by step what to do. http://www.cisco.com/en/US/products/hw/switches/ps708/products_configuration_example09186a0080a98f3c.shtml#Hybrid
I'm only trying to upgrade IOS not CatOS, but in that document there were a lot of redundancy commands that I think the IOS version I have doesn't have.
I already tried upgrading the MSFC3, with no success, I want to move to version 12.2(18)SXF16 per cisco recommendation. but It'll be really nice if someone had the correct document to do the upgrade for Dual supervisors would be really helpful.
Thanks in advance.
