Irf Physical Interface Requirements; Connecting Irf Ports; Licensing Requirements; Example: Setting Up A Four-Chassis Lacp Mad-Enabled Irf Fabric - H3C S6890 Series Configuration Examples

IRF physical interface requirements

Use the following ports on the S6890 switch for IRF links:
•
SFP+ ports.
•
QSFP28 ports.

Connecting IRF ports

When you connect two neighboring IRF members, connect the physical interfaces of IRF-port 1 on
one member to the physical interfaces of IRF-port 2 on the other.

Licensing requirements

For a license-based feature to run correctly on an IRF fabric, make sure the licenses installed for the
feature on all member devices are the same. For more information about feature licensing, see
Fundamentals Configuration Guide.

MAD-enabled IRF fabric

Network configuration

As shown in
access layer of the data center. The access-layer IRF fabric provides Layer 2 forwarding services.
Run LACP MAD to detect IRF split.
