Please consider the following example:
host 184.108.40.206--220.127.116.11 f0/0 MX5---F0/1-------
Above we have mapped DSCP EF to queue 2 on MX5
Host 18.104.22.168 is sending traffic with DSCP EF.
MX5 is also receiving EF traffic from other hosts on f0/0 ( not shown) which are eggressing f0/1.
I could use show interface queue f0/1 and see if queue2 counter but it will show aggregate not just host1's traffic.
Is there any way we can find out if host 22.214.171.124 with DSCP EF is being placed in queue2 on f0/1 on MX2?
Thanks and have a good weekend!!
I hope you are having a blast! as you mentioned the output interface will aggregate all streams marked with EF to queue 2 hence I don't think and I have not found a way to see traffic for specific steam with a specific command, Nevertheless, you can place a network device facing f0/1 and use a firewall filter to count packets using the following matching criteria: from the source IP 126.96.36.199 and with DSCP EF in the ingress direction example:
host---f0/0-MX-f0/1--- [ingress FF(another network device)]
Please use rewrite rules on the MX to make sure the (network device) will receive the traffic with the EF DSCP
You can try a filter in the egress direction on the MX but I am not sure if this is supported since actions like then count or then log are not supported in a lot of devices in the egress direction.
If this solves your problem, please mark this post as "Accepted Solution" so we can help others too \:)/
