Configuring uplink interfaces
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter VFC interface view. interface vfc
interface-number
This VFC interface is connected to the core switch.
3. Set the mode of the VFC
interface to NP.
fc mode np The default setting is F mode.
Configuring downlink interfaces
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter VFC interface
view.
interface vfc interface-number This VFC interface is connected to a node.
3. Set the mode of the
VFC interface to F.
fc mode f The default setting is F mode.
Configuring downlink-to-uplink interface mappings
CAUTION:
If an uplink interface mapped by a downlink interface is not in the configured mappings, the switch
initializes the downlink interface, resulting in traffic interruption.
NPV switches automatically map downlink interfaces to uplink interfaces. Typically, automatic mapping
can meet your requirements. When a downlink interface must be connected to a fabric through the
specified uplink interfaces, you can manually map the downlink interface to the uplink interfaces.
After you configure the mapping, the downlink interface can be mapped to only the configured uplink
interfaces. If none of the configured uplink interfaces is operational, the downlink interface cannot be
operational. A configured mapping selects the uplink interface with the minimum load from configured
uplink interfaces and then maps the downlink interface to it.
To configure a downlink-to-uplink interface mapping:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter VSAN view. vsan vsan-id N/A
3. Configure a
downlink-to-uplink
interface mapping.
npv traffic-map server-interface
interface-type interface-number
external-interface interface-type
interface-number
By default, no mapping is configured.
