I dont' know what router you're using, but here's the basic config that you can use if your router can support NBAR.
class-map match-all VOIP
match ip dscp ef
class-map match-any Call-Signaling
match ip dscp cs3
class-map match-any Critical-Data
match protocol http
match protocol ftp
match protocol smtp
class-map match-any Network-Control
match ip dscp cs6
class-map match-all Scavenger
match ip dscp cs1
policy-map LAN-QoS
class VOIP
priority percent (% of bandwith you want to allocate)
class Call-Signaling
bandwidth percent 5
class Network-Control
bandwidth percent 5
class Critical-Data
set ip dscp af21
bandwidth percent (% of bandwith you want to allocate)
random-detect dscp-based
class Scavenger
bandwidth percent 1
class class-default
bandwidth percent (% of bandwith you want to allocate)
random-detect dscp-based
Then apply this policy-map LAN-QoS to your interface:
- service-policy output LAN-QoS.
By default, Cisco only allows 75% of configured bandwidth, so if you want to use 100% of it, you will need to add this command "max-reserved bandwith 100" to the same interface that you're applying the policy-map.
After applying the policy, you can use this command "sh policy-map interface xxx" to monitor packet hits.
