Hi Folks!
I'm configuring QoS for a large network and I have some doubts about
Policy-maps. I configured this policy:
policy-map QoS
class voice
priority 24
class very-high
bandwidth percent 10
class high
bandwidth percent 20
class medium
bandwidth percent 30
class low
bandwidth percent 40
class class-default
fair-queue
random-detect
As you can see, I gave 24 Kbps for voice packets with the "priority"
command. There are four other classes to which I gave 10, 20, 30 and 40
percent of the bandwidth. I also have a default class, that will match
packets not matching the other classes.
My question is: how much of the bandwidth will be reserved for each class??
Someone told me that 25% of the bandwidth is automatically reserved to the
class-default, but I couldn't find this on any document. Is that correct??
If yes, and assuming that I4m talking about a 64 Kbps link, then I would
have 16 Kbps (25% of 64Kbps) to the class-default, 24 Kbps to the voice
class and 24 Kbps to be divided through the 4 other classes by the
"bandwidth percent" command, which would give me 2.4Kbps, 4.8Kbps, 7.2Kbps
and 9.6Kbps. Is that correct???
I'll appreciate any help!
Thanks!!
