Qos Map Phb-Queue; Table 125: Mapping Internal Per-Hop Behavior To Hardware Queues - Edge-Core ES3510MA-DC Management Manual

qos map phb-queue

map should be applied at the receiving port (ingress mutation) at the
boundary of a QoS administrative domain.
Random Early Detection starts dropping yellow and red packets when
◆
the buffer fills up to 0x60 packets, and then starts dropping any
packets regardless of color when the buffer fills up to 0x80 packets.
The specified mapping applies to all interfaces.

XAMPLE
This example changes the priority for all packets entering port 1 which
contain a DSCP value of 1 to a per-hop behavior of 3 and a drop
precedence of 1. Referring to

This command determines the hardware output queues to use based on
the internal per-hop behavior value. Use the no form to restore the default
settings.
