Figure 3 Troubleshooting IRF fabric establishment failure
Solution
To resolve the issue:
1.
Verify that the switch models can form an IRF fabric:
a.
Verify that the member switches are from the same switch series.
b.
Use the virtual technologies configuration guide for the switch series to verify whether the
switches in the switch series are grouped for IRF compatibility. If they are grouped, make
sure the IRF member switches are from the same IRF compatibility group.
