Configuring The Global Load Sharing Mode; Configuring A Port-Specific Load Sharing Mode; Configuring Irf Bridge Mac Persistence - H3C S5150-EI Series Configuration Manual

•
In system view, the configuration is global and takes effect on all IRF ports.
•
In IRF port view, the configuration is port specific and takes effect only on the specified IRF port.
An IRF port preferentially uses the port-specific load sharing mode. If no port-specific load sharing
mode is available, the IRF port uses the global load sharing mode.
The IRF link load sharing mode takes effect on all types of packets, including unicast, multicast, and
broadcast.
IRF link load sharing mode cannot take effect if the criterion of destination port or source port is
configured for the global link-aggregation load sharing mode. Traffic is distributed among IRF links
based on destination ports or source ports. For information about global link-aggregation load
sharing mode configuration, see Layer 2—LAN Switching Configuration Guide.

Configuring the global load sharing mode

Step
1. Enter system view.
2. Configure the global IRF
link load sharing mode.

Configuring a port-specific load sharing mode

Before you configure a port-specific load sharing mode, make sure you have bound a minimum of
one physical interface to the IRF port.
To configure a port-specific load sharing mode for an IRF port:
Step
1. Enter system view.
2. Enter IRF port view.
3. Configure the port-specific
load sharing mode.

Configuring IRF bridge MAC persistence

By default, an IRF fabric uses the bridge MAC address of the master device as its bridge MAC
address. Layer 2 protocols, such as LACP, use this bridge MAC address to identify the IRF fabric. On
a switched LAN, the bridge MAC address must be unique.
To avoid duplicate bridge MAC addresses, an IRF fabric can change its bridge MAC address
automatically after the address owner leaves. However, the change causes temporary traffic
disruption.
Depending on the network condition, enable the IRF fabric to retain or change its bridge MAC
address after the address owner leaves. Available options include:
Command
system-view
irf-port global load-sharing mode
{ destination-ip | destination-mac |
source-ip | source-mac } *
Command
system-view
irf-port member-id/irf-port-number
irf-port load-sharing mode
{ destination-ip | destination-mac |
source-ip | source-mac } *

By default, packets are
distributed automatically across
IRF member links based on
packet types.
If you execute this command
multiple times, the most recent
configuration takes effect.
