Hi sir
i suggest you cofiguration the QOS to management the traffic
When congestion occurs on a network, the device configured with bandwidth management preferentially ensures that key services obtain bandwidth and limits the uplink and downlink rates of non-key services.
Bandwidth management technology provides bandwidth guarantee and limiting to improve the bandwidth use efficiency and prevent bandwidth exhaustion.
Bandwidth guarantee: guarantees the bandwidth required by key services. When a network is busy, the bandwidth for key services is not affected.
Bandwidth limiting: limits the bandwidth occupied by non-key services, and prevents the non-key services from consuming much bandwidth to affect other services.
Bandwidth management helps network administrators properly allocate bandwidth resources, thereby improving the network operation quality.
