mplsgrzpe01#

the problem is that if i make a "sh policy-map int gig1/1/1.1702" the time update time is very long, although load-interval is set to 30 seconds.

for example if there is traffic with 300kb/s in voice-queue, it takes a long time (till minutes that the "offered rate" is 300 kb/s).

if i stop forwarding traffic to the voice-queue, it also takes minutes, tille the "offered-rate" value goes down to zero bits per seconds.

Cisco IOS Software, c7600rsp72043_rp Software (c7600rsp72043_rp-ADVIPSERVICESK9-M), Version 12.2(33)SRB2,

System image file is "bootdisk:c7600rsp72043-advipservicesk9-mz.122-33.SRB2.bin"

Last reload type: Normal Reload

the next problem is, that we have drops in our voice_queue althoug there is 380kb/s reserved in voice-queue and we do NOT exceed this value

thanks for any help
