I've tried using Red and PCQ both to limit bandwidth down to 256k/128k only for specific IP addresses, actually we have 2 class c's I setup simple queues for each IP which was 2 simple queue rules per IP which in the end is around 400 simple queue rules, this caused the load on the router to go to 100% so I removed them, was having trouble with them getting added anyway, PCQ was doing a set amount of bandwidth for example 256k and sharing it only for that class not IP based, I'm not sure what we should be using to limit bandwidth per IP and I don't want the CPU load to be just 100% on a constant basis, if anyone has any ideas let me know, but here's an example of one of my rules for the simple queue I was using.
add name="10.104.4.11-D" target-address=10.104.4.11/32 dst-address=0.0.0.0/0 interface=C900 \
queue=Red priority=8 limit-at=256000/256000 max-limit=256000/256000 \
burst-limit=512000/512000 burst-threshold=126000/126000 burst-time=60/60 disabled=no
add name="10.104.4.11-U" target-address=10.104.4.11/32 dst-address=0.0.0.0/0 interface=GW queue=Red \
priority=8 limit-at=0/0 max-limit=128000/128000 disabled=no
add name="10.104.4.12-D" target-address=10.104.4.12/32 dst-address=0.0.0.0/0 interface=C900 \
queue=Red priority=8 limit-at=256000/256000 max-limit=256000/256000 \
burst-limit=512000/512000 burst-threshold=126000/126000 burst-time=60/60 disabled=no
add name="10.104.4.12-U" target-address=10.104.4.12/32 dst-address=0.0.0.0/0 interface=GW queue=Red \
priority=8 limit-at=0/0 max-limit=128000/128000 disabled=no
add name="10.104.4.13-D" target-address=10.104.4.13/32 dst-address=0.0.0.0/0 interface=C900 \
queue=Red priority=8 limit-at=256000/256000 max-limit=256000/256000 \
burst-limit=512000/512000 burst-threshold=126000/126000 burst-time=60/60 disabled=no
add name="10.104.4.13-U" target-address=10.104.4.13/32 dst-address=0.0.0.0/0 interface=GW queue=Red \
priority=8 limit-at=0/0 max-limit=128000/128000 disabled=no
^ above shows you 3 ip addresses simple queue rules
I'd be extremely appreciative of any ideas anyone has to fix this bandwidth control issue, what we have is 4 packages, a basic (256k/128k) , a bronze, a silver and a gold all have different speeds of bandwidth which need limited by IP address, most routers have 2 class c's so their would be a great deal of rules, please help.
