Simple Cisco QOS configuration. Since a couple of days back I had to configure QOS on a Cisco router with 5 mbit of synchrone internet connection. To archive a configuration I had to figure out if i could find a simple way to create a QOS templete for VOICE & Citrix combined.
Step one [ configuring an access list for citrix ]:
ip access-list extended CITRIX permit tcp <ip range of lan + wildcard subnet> any eq 1494 permit tcp <ip range of lan + wildcard subnet> any eq 2598 permit udp <ip range of lan + wildcard subnet> any eq 2598 permit udp <ip range of lan + wildcard subnet> any eq 1494
Step two [configuring an Policy map ]:
policy-map QOS class VOICE priority 1024 [ this 1024 I used for the continue bandwidth limit for voice ] set dscp ef class CITRIX bandwidth remaining percent 50 [ this is the remaining bandwidth limit for citrix ] set dscp af43 class class-default fair-queue [ This is the rest of the bandwidth which is available for usage ] set dscp default policy-map ALL class SHAPING shape average 4750000 [ this is the shaped speed of the internet line ] service-policy QOS
Step three [ configering class-maps]:
class-map match-all CITRIX match access-group name CITRIX class-map match-all SHAPING match any class-map match-all VOICE match access-group name VOICE
After this you need to actived all the QOS settings to the interface you need it.
interface FastEthernet0/0 bandwidth 5000 max-reserved-bandwidth 100 service-policy output ALL
