Setup:
Cisco Catalyst 2970G 28Port Gigabit Switch WS-C2970G-24TS-E
GigabitEthernet0/1 connected to DSL equipement connecting to the Internet
GigabitEthernet0/9 connected to the network that is to limit its equipments outbound Internet speed.
This is what I have configured so far:
access-list 101 deny ip 192.168.1.0 0.0.0.255 192.168.1.0 0.0.0.255
access-list 101 permit ip any any
mls qos srr-queue output dscp-map queue 2 threshold 1 38
this puts anything marked with DSCP decimal 38 into queue 2
policy-map intg09
class intg0
set ip dscp af43
this assigned to g0/9 sets traffic as per the ACL to be DSCP af43 (decimal 38)
interface GigabitEthernet0/9
service-policy input intg09
!
this shows the policy applied to the interface
interface GigabitEthernet0/1
srr-queue bandwidth share 10 1 1 1
priority-queue out
This gives queue 1 priority over everything and ten times more packets serviced than queues 2/3/4
Queue 1 would be everything other than traffic from Gi0/9
Queries:
Overall it does not appear to be working, as traffic from say Gi0/9 and Gi0/10 equally share the outbound bandwidth to the internet
It appears that any traffic from equipment on GigabitEthernet0/9 even if it is not destined for the Internet (GigabitEthernet0/1) is limiting its LAN speeds.
Something that might be related to the above, is that I am monitoring the Traffic on (GigabitEthernet0/1) via:
monitor session 1 source interface Gi0/1
monitor session 1 destination interface Gi0/3
but am seeing a lot of non Internet related traffic on Gi0/1, via its SPAN on Port 3.
ie/ Traffic from a Host on Gi0/15 to a Host on Gi0/16 or Hosts on Gi0/09(with the above QOS) to a Host on Gi0/16
Any ideas of my issues?
