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
.
Example: Setting up a four-chassis LACP
MAD-enabled IRF fabric
Network configuration
As shown in
, use a four-chassis IRF fabric to replace the ToR switches in
at the
access layer of the data center. The access-layer IRF fabric provides Layer 2 forwarding services.
Run LACP MAD to detect IRF split.
