Short answer: What command doubles the capacity of Priority Queuing's highest-level queue?

Answer: This is an odd command in that even if you're just changing one queue's capacity, you have to list all four queue capacities. When I try to just change the High queue, this is what happens:

R1(config)#priority-list 1 queue-limit 40
% Incomplete command.

I have to set all four queue sizes. Watch that!

R1(config)#priority-list 1 queue-limit 40 ?
<0-32767> Medium limit
R1(config)#priority-list 1 queue-limit 40 40 60 80

New questions posted later today!

To your success,
