One of the Server ports (pointing towards a UCS Chassis) on my fabric interconnect is currently showing as down as it is Trunk mode not Fabric Mode as per all the other server ports.
For some reason when I look under the LAN tab this one interface is showing under "internal LAN". I have tried disabling and/or deleting the interface from under "internal LAN" however every time I re-configure the port as a Server Port it is showing back under and the mode remains in Trunk.
Does anyone have some advice how I can get this port out of Trunk Mode and into Fabric Mode?
Many Thanks, Paul
The port will be on Trunk when it is not getting proper connectivity between the IOM and the FI.
Check the physical connection and make sure the cable is properly seated at both ends.
If possible, try a different cable.
You can also try:
- Unconfigure the port
- Configure it as uplink
- Disable it
- Reconfigure as server.
What is the chassis discovery policy?
How many links are connected between IOMs and FI?
Thanks Zaira for getting back to me.
I have tried your suggested steps to resolve this and unfortunately this has not resolved the problem.
However to confirm when we moved the "faulty" optic/cable to new ports to a new location and it worked so would indicate this is not an issue with the optics or cables.
The chassis discovery policy is 1 link and there are 2 links between the IOMs/FIs.
Does the interface report any fault?
Is the interface able to confirm the presence of the optic cable?
What happens if you try setting up the interface as a uplink port?
Did the issue perists?
