Make Cisco Routers Microwave Bandwidth Aware If Adaptive Coding Modulation (ACM) is activated on a point-to-point microwave link, the link’s bandwidth varies based on propagation conditions. The variation of the link capacity becomes problematic when microwave links provide a Layer 2 circuit between routers.
When a router is connected to the microwave indoor unit with a 1 Gbps Ethernet port, from the router perspective, the link bandwidth is 1 Gbps but in reality the capacity could vary between 1 and 1000 Mbps based on the modulation and channel size.
If the router is unaware of the microwave link capacity it cannot prioritize important traffic in case of congestion nor can it select the optimal path when multiple paths are available.
