This carries the specific alarm-threshold value (in whatever bandwidth unit the CAC policy uses) that was crossed to trigger this notification, telling the admin how close to full admission capacity the interface actually is. Because this value is the configured trigger point rather than the live utilization, an admin compares it against the interface's actual reserved bandwidth to gauge how much more traffic-engineered capacity remains before new LSP requests start being rejected. For example, a threshold value of 800000 (kbps) crossed on a 1 Gbps interface tells the admin new LSP admission on this class is now being throttled at 80% utilization.
