Sup720 PFC upgrade to PFC3B

I just found out(the hard way) that I need the PFC3B card in my Sup720 in order to have Netflow data include the TOS field. Is the PFC a field upgradable component on the Sup720? If so, is it pretty straight forward to upgrade and do I need to upgrade the version of IOS(native mode) or CatOS (hybrid mode) to support the new card?

Re: Sup720 PFC upgrade to PFC3B

Couple of things.

1. PFC is a field replaceable unit ( FRU ) which means you can just buy a PFC3-B and put it on baseboard to make it a sup720-3B , however , there is one caveat . There are certain features that you may still not be able to use ( ERSPAN is one example ) if you just upgraded the PFC , but not the base board . Even though you wont be able to tell the difference between the 2 , there are still some differences if you were to buy a new sup720-3B or converting an existing sup720-3a into a sup720-3b but just upgrading a pfc on it , so please weigh your options.As I said , ERSPAN will work on a new sup720-3B , but not on a sup720 that is just upgraded from sup720-3a to a 3b system.

2. Typically a code upgrade would be required to support a new card depending on which code you are on right now.

Hope this helps.

Thanks

Re: Sup720 PFC upgrade to PFC3B

That is good news for me. In regards to features that won't be supported, it sounds like it won't be any less than what I have today. But to be sure, is there a document that list the features that won't be supported if I go from a PFC3A to a PFC3B?

And as far as CatOS and IOS go, what are the minimum versions to support the PFC3B. We are running 8.4(2a) CatOS and 12.2.18(SXF10).

I am not aware of a document specifically listing caveats / features that you will get from going from sup720-3a to 3b. It is true that you wont lose any.

thanks
