hi there,
Dont have acccess to rack right now, so ignore typos
Logic is
1. Grab the "interesting traffic " on R2
2. define class map and match relevant acl
3. define policy map, use class-map and apply apprioprate QoS
4. Apply Policy map to the interface OUTBOUND
R2
access-list 100 permit UDP host 2.2.2.10 eq 7777 1.1.1.0 0.0.0.255
access-list 101 permit TCP host 2.2.2.10 eq 7777 1.1.1.0 0.0.0.255
class-map UDP_TRAFFIC
match access-group 100
class-map TCP_TRAFFIC
match access-group 101
policy-map SET_PRIORITY
class UDP_TRAFFIC
priority 3000
class TCP_TRAFFIC
priority 2000
interface Ethernet 0/1
service-policy output SET_PRIORITY
I'd appreciate if any one else can comment on this config
Kind Regards
Zafar Khan
