What is snAgentHwICBMCounterFreeDepth?

This gauge measures the current available capacity in the free queue for an ICBM (Intelligent Cluster Backplane Module) hardware component in a Foundry switch. System administrators monitor this value to track memory buffer utilization and detect when the hardware is running low on free buffers for packet processing. A consistently low free depth indicates the hardware is near saturation and may begin dropping packets if congestion increases.
