Impact of QoS queue configuration on guaranteed minimum bandwidth (GMB)
Changing the number of queues removes any
bandwidth-min output settings in the startup configuration, and automatically re-allocates the GMB per queue as shown in the following table.
| 802.1p priority | 8 Queues (default) | 4 Queues | 2 Queues | |||

| 1 (lowest) | 1 | 2% | 1 | 8% | 1 | 20% |
| 2 | 2 | 3% | ||||
| 0 (normal) | 3 | 30% | 2 | 17% | ||
| 3 | 4 | 10% | ||||
| 4 | 5 | 10% | 3 | |||
| 5 | 6 | 10% | 4 | 30% | 2 | 80% |
