[QoS] Does using set-dscp-transmit in a policer re-queue the packet?

[kishanpatel500]

Hi,

I'm using a policer within a class on an egress WAN interface of a remote site router.

The policer guarantees a minimum of 1Mbps of interesting traffic using bandwidth 1024.

The policer also remarks to default for any traffic exceeding this amount.

Does the traffic that exceeds 1Mbps get re-queued to account towards the class-default queue or does this packet still use up the interesting traffic queue?

I believe, normally, a remarked packet, if remarked by an ingress policer, will treated as it if it had that marking upon egress.  I also believe, a remarked packet, if remarked by an egress policer, will continue to remain with other like egress traffic (i.e. the remarking doesn't change egress for that packet).

The remarking will occur on egress however, what i mean is that will the remarked packet add to the queue-depth of the HTTPS queue or the class-default queue.
