I have two 6509 switches with single SUP2 engines (WS-X6K-SUP2-2GE) with PFC2 and MSFC2 in each switch. I want to convert to native IOS on these switches and add redundent SUP's for failover. However, the spare SUP's I have are the same as the ones in production but do not have the MSFC2 router feature card installed.
Is the MSFC2 router feature card necessary when adding the redundent SUP's that don't have that installed? Can I still function the same after the conversion with out using the MSFC2 feature?
