Catalyst Hybrid vs. Native IOS

Why go from Catalyst to Native IOS?

Do you loose or gain features either way? (ie. Hybrid Dual Supervisor support)

What about requirements: Is there going to be a need to upgrade FLASH/DRAM?

Since the RSM, MSFC and MSFC are seperate and appear to use seperate FLASH and DRAM, are these somehow combined?

Re: Catalyst Hybrid vs. Native IOS

Few previous posts in Netpro should help

There are few features which are specific to each OS. The release notes should be a good place to start

For example, VOice modules such as 6608-T1 and 6624 are currently not supported in native IOS. Stateful failover of Sups(if you have 2 Supervisor) is not supported yet in native IOS

Existing DRAM should be good enough but Flash requirements depend on the software version you plan to upgrade to. In native IOS system, the switch and the MSFC will be booting from either Supervisor bootflash or PCMCIA card. If you have 32MB Supervisor bootflash, you can upgrade to any native IOS. If you have 16MB bootflash, you'll need to use a PCMCIA card or upgrade bootflash

Hope this helps
