Dell S5148F-ON OS10 Enterprise Edition User Guide Release 10.3.2E-R1 - Page 147

Usage Information Example A device receiving BPDUs waits until the max-hops value expires before discarding it. When a device receives the BPDUs, it decrements the received value of the remaining hops and uses the resulting value as remaining-hops in the BPDUs. If the remaining MSTP 1333 hops reach zero, the device discards the BPDU and ages out any information that it holds for the port. The command configuration applies to all common IST (CIST) in the MST region.
