Multiple secondary IPs on a Cisco 6500?

The 6506 as a *switch* does not have IP addresses for VLANs (except perhaps for the management vlan.)

The 6506 with a routing card in it that is supporting IOS allows multiple secondary IPs for VLAN interfaces [unless for some reason they removed that facility in a later IOS.]

Hi,

For the Cat6k switch, you can run into the following mode:

1. Hybrid , A layer 2 box with Layer 3 MSFC (CatOS + IOS)
2. Native IOS, A Layer 3 box where the sup and the MSFC driven by Naive IOS.

In Hybrid: The sup will have its own management sc0 interface. And the MSFC, is like a router, you can have different IP addresses assigned to different Layer 3 Vlan interfaces.

Hope it helps,

Cheers, CC

If the 6506 has an MSFC and is running native IOS, that distinction is no longer true.

Nope, it's still possible.

Yes, we have a supervisor card (MSFC2). I believe it is running in hybrid mode, since the switch part is running CatOS and the router part is running IOS.

Thanks for the information guys. We are converting from Avaya to Cisco equipment. It sounds like I will be able to use several (more than 2) IPs on a single VLAN interface.
