ATM Protocol Prioritization and Priority Queuing
308645-15.0 Rev 00
9-15
Grouped PVCs, Hybrid PVCs and WAN SVCs
Since filter tables are configured at the service level, grouped PVCs, hybrid PVCs,
and WAN PVCs use the same filter table, although queuing and dequeuing take
place independently for each VC (Figure 9-7). Statistics are maintained on a
per-service basis but do not reflect the statistics of the component VCs.
