| 0 | Total | 50 | 0 | VT_RATE_COUNTER | Bps | This meter reports the combined bandwidth rate for traffic to and from this IPv6 prefix, as learned from the router's routing information base. |
| 1 | Recv from Upstream AS | 50 | 0 | VT_RATE_COUNTER | Bps | This meter reports the bandwidth rate for traffic to this IPv6 prefix received via an upstream (transit provider) AS. |
| 2 | Transmit to Upstream AS | 50 | 0 | VT_RATE_COUNTER | Bps | This meter reports the bandwidth rate for traffic to this IPv6 prefix transmitted via an upstream (transit provider) AS. |
| 3 | Prefixes Flows | 50 | 0 | VT_COUNTER | Flws | This meter reports the number of flow records observed for this IPv6 prefix within the collection interval. |
| 4 | Recv from Downstream AS | 50 | 0 | VT_RATE_COUNTER | Bps | This meter reports the bandwidth rate for traffic to this IPv6 prefix received via a downstream (customer) AS. |
| 5 | Transmit to Downstream AS | 50 | 0 | VT_RATE_COUNTER | Bps | This meter reports the bandwidth rate for traffic to this IPv6 prefix transmitted via a downstream (customer) AS. |
| 6 | Unused Cardinality counter | 20 | 20 | VT_GAUGE | Uniques | This is a reserved gauge slot intended for a unique value cardinality metric. It is not currently mapped to any field for this counter group, so it remains an inactive placeholder with no data populated. |
| 7 | Unused Cardinality counter | 20 | 20 | VT_GAUGE | Uniques | This is a second reserved cardinality gauge slot with the same status as meter 6. It is inactive and not instrumented for this group. |
