Hi, this is my issue, we have remote sites which use a central internal server to run 'Windows Updates', everytime a PC starts to run 'Windows Updates' the network on that remote site gets congested then the phones stop working. Is there any way to prevent 'Windows Updates' to utilize 100% of the available bandwidth?
I have a policy map configured and www(http) is set on the low priority, but it seems that is not enough... here is what I got.:
class-map match-all HI
match access-group name hiclassacl
class-map match-all LO
match access-group name loclassacl
class-map match-all RT
match access-group name rtclassacl
policy-map AVPNCOS
class RT
set ip dscp ef
priority 600
class HI
set ip dscp af31
bandwidth remaining percent 60
class LO
set ip dscp af21
bandwidth remaining percent 30
class class-default
set ip dscp default
bandwidth remaining percent 10
