Step 2: T1 Member Goes Down, Bandwidth Requirement OK
In this step, one T1 member goes down. The total of priority policing plus minimum guaranteed
bandwidth is 13 Mbps. This is still lower than the bundle link bandwidth, which is 13,824 Mbps (1,536
kbps * 9 T1 members). It still meets the bandwidth requirement. The policy is still applied at the bundle
interface.

Serial0/2/1/0/1/1:0, changed state to Administratively Down
Step 3: Another T1 Member Goes Down, Bandwidth Requirement Exceeded
In this step, another T1 member goes down. The total of priority traffic plus minimum guaranteed
bandwidth is 13 Mbps. This is now higher than the bundle link bandwidth, which is 12,288 Mbps (1,536
kbps * 8 T1 members). Because it exceeds the bandwidth requirement, the policy is suspended from the
bundle interface.
