R21xx-HP FlexFabric 11900 FCoE Command Reference

84
external-interface interface-type interface-number: Specifies an uplink interface by its type and number,
which can be a VFC interface.
Usage guidelines
When uplink-to-downlink interface mappings are configured for a downlink interface, the downlink
interface can select an uplink interface to map from only the uplink interfaces mapped to the downlink
interface. If no uplink-to-downlink interface mapping is configured for the downlink interface, it can select
an uplink interface to map from all uplink interfaces in the same VSAN.
This command is available only when the switch is operating in NPV mode.
Examples
# Configure a mapping between VFC1 (downlink interface) and VFC2 (uplink interface).
