      To modify the attributes of Fibre Channel link "4", where bandwidth limitation will be enabled, the bandwidth threshold is "400M", and the bandwidth utilization rate is "80%", run the following command.
              admin:/>change remote_device link link_type=FC link_id=4 bandwidth_limit_enabled=yes bandwidth=400M bandwidth_utilization_rate=80
              WARNING: You are going to modify the parameters of the link (source-target information). A link bandwidth above the threshold affects the performance of other services, and a link bandwidth below the threshold affects the performance of the current service. Changing the IP address information of the link or fast_write policy may cause link reconnection that interrupts services.
              Suggestion: Before you set the link threshold, determine the link bandwidth that is actually required and the bandwidth that can be allocated from the physical link to the current connection. Before you modify the IP address information and fast_write policy, check whether any standby replication link exists;Whether the fast_write policy should take effect instantly is determined after the driver negotiation.
