hi, I am trying to establish ESI between Swicth5 and leaf swicthes, NXOS2 and NXOS3, but for some reason, it fails on swicth 5. It comes up for a minute and then goes down citing "channel-misconfig (STP) error detected on Po10".
Code on NXOS: nxos.9.3.10.bin
Code on vIOS: vios_l2-adventerprisek9-m
Note: I have attached show run as an attachment. Shared below is the design.
