Basic IP forwarding commands
display fib
Use display fib to display FIB entries.
Syntax
display fib [ ip-address [ mask | mask-length ] ]
Views
Any view
Predefined user roles
network-admin
network-operator
Parameters
ip-address: Displays the FIB entry that matches the specified destination IP address.
mask: Specifies the mask for the IP address.
mask-length: Specifies the mask length for the IP address, the number of consecutive ones in the mask. The value range is 0 to 32.
Usage guidelines
Each FIB entry contains a destination IP address/mask, next hop, and output interface.
If you specify an IP address without a mask or mask length, this command displays the longest matching FIB entry.
If you specify an IP address and a mask or mask length, this command displays the exactly matching FIB entry.
Examples
# Display all FIB entries of the public network.
<Sysname> display fib
Destination count: 9 FIB entry count: 9

Load sharing commands
ip load-sharing local-first enable
Use ip load-sharing local-first enable to enable local-first load sharing.
Use undo ip load-sharing local-first enable to disable local-first load sharing.
Syntax
ip load-sharing local-first enable
undo ip load-sharing local-first enable
Default
Local-first load sharing is enabled.
Views
System view
Predefined user roles
network-admin
Usage guidelines
Local-first load sharing takes effect only in an IRF fabric.
Examples
# Disable local-first load sharing.
[Sysname] undo ip load-sharing local-first enable
ip load-sharing mode per-flow
Use ip load-sharing mode per-flow to configure per-flow load sharing.
Use undo ip load-sharing mode per-flow to restore the default.
Syntax
ip load-sharing mode per-flow [ algorithm algorithm-number | [ dest-ip | dest-port | ingress-port | ip-pro | src-ip | src-port ] * ] [ slot slot-number ]
undo ip load-sharing mode [ slot slot-number ]
Default
The device performs per-flow load sharing based on the source IP address, destination IP address, source port, destination port, IP protocol number, ingress port, and VLAN.

Parameters
algorithm algorithm-number: Enables flow-based load sharing algorithm switching. The algorithm-number argument specifies the algorithm to be switched, and is in the range of 0 to 8. Value 0 indicates the default algorithm.
dest-ip: Identifies flows by destination IP address.
dest-port: Identifies flows by destination port.
ingress-port: Identifies flows by ingress port.
ip-pro: Identifies flows by protocol ID.
src-ip: Identifies flows by source IP address.
src-port: Identifies flows by source port.
slot slot-number: Specifies an IRF member device by its member ID.
Examples
# Configure per-flow load sharing on IRF member device 2.
<Sysname> system-view
[Sysname] ip load-sharing mode per-flow slot 2
