VSI Is Up on Only One End

Procedure

1. Run the display vsi [ name vsi-name ] [ verbose ] command to check whether multiple AC interfaces on the local end are bound to the VSI.

   If fewer than two interfaces are bound to the VSI, you need to configure the local and remote ends to bind more than two AC interfaces to the VSI.

   

   If two or more AC interfaces are bound to the VSI, the VSI can be Up.

2. Check whether the remote end specifies the local end as the UPE.

   If the remote end specifies the local end as the UPE and the remote AC interface are faulty, the remote end does not notify the local end of the fault. This may cause VSI in Up state on only one end.
