> # Configuring Fibre Channel Interfaces

> For the Cisco Fabric Switch for HP c-Class BladeSystem and the Cisco Fabric Switch for IBM BladeCenter, you can configure a range of interfaces among internal ports or external ports, but you cannot mix both interface types within the same range. For example, “bay 1-10, bay 12” or “ext 0, ext 15-18” are valid ranges, but “bay 1-5, ext 15-17” is not.
