Migrating 6500 Hybrid configuration to NEW 6500 running IOS

Unanswered Question
Aug 6th, 2009


I have several 6509 switches (most access, a couple distribution) currently in Hybrid mode. As part of an upgrade project, all of these switches are being replaced with new hardware, which will be on IOS software.

I would like to know what is the best way to migrate the existing configurations onto the new devices. The current devices have both L2/L3 configurations, while the NEW devices will be strictly L3.

It would seem that the ENTIRE L3 (MSFC) config would still be needed on the NEW device - unless I am mistaken. However, what would still be required from the L2 side that would need to be migrated.

Any help would be greatly appreciated!



I have this problem too.

"The current devices have both L2/L3 configurations, while the NEW devices will be strictly L3."

Not sure what you mean by this. You will still need L2 configuration on the switch if the switches are to function as they do now in hybrid mode. The only difference is that instead of using CatOS for L2 you now use IOS for L2 and L3.

So which bits would you need apart from the MSFC config. Well without knowing what you have configured it's difficult to be precise but it's safe to say you will need

1) vlans

2) allocation of ports into those vlans

3) VTP if you are using it already

4) STP configuration

5) Any trunk configurations

6) etherchannel configurations

+ anything else you have configured.

Sorry, misspoke. I meant to say the NEW devices would be strictly IOS. However, they will have L2 (switch port) and L3 (routing protocol) function.

In terms of the migration from Hybrid to IOS, it would seem that the MSFC configuration would be transparent (that is, could be applied as is since it is already IOS). However, the L2 configuration from the Hybrid device would need updating, such as the VLAN information, etc. This is what I wanted to confirm and on which I wanted to find more information.
