Hello ,

I am trying to use tc to do the following ..on the interface(eth0) I want to give priority to  to packets coming from a specific IP address 1.2.3.4 over packets from  IP address 1.2.3.5 .

I would like to know if the following setup would work with PRIO qdisc.

tc qdisc add dev eth0 root handle 10 : prio

tc filter add dev eth0 parent 10:0 protocol ip prio 1 u32 \
match ip src 1.2.3.4/32 flowid 10:1

tc filter add dev eth0 parent 10:0 protocol ip prio 1 u32 \
match ip dst 1.2.3.4/32 flowid 10:1

tc filter add dev eth0 parent 10:0 protocol ip prio 1 u32 \
match ip src 1.2.3.5/32 flowid 10:2

tc filter add dev eth0 parent 10:0 protocol ip prio 1 u32 \
match ip dst 1.2.3.5/32 flowid 10:2

Can I test this setup by using flooding ping from 1.2.3.4 and 1.2.3.5 to the machine configured with tc ?

I expected that pings from 1.2.3.5 will be dropped giving priority to 1.2.3.4

Looking forward to your input,

Andreas.
