# Add traffic policing action to the QoS profile named a123 to limit the rate of the inbound packets
sourced from IP address 1.1.1.1 to 128 kbps and drop the packets exceeding 128 kbps.

Parameters
inbound : Performs priority marking on the inbound packets.
outbound : Performs priority marking on the outbound packets.

keywords listed in Table 1-7 for the dscp-value argument.
ip-precedence { pre-value | from-cos }: Sets the IP precedence. The pre-value argument ranges from
0 to 7. You can also provide one of the keywords listed in Table 1-6 for the pre-value argument. The
from-cos keyword specifies to use the 802.1p priority as the IP precedence.
cos { pre-value | from-ipprec }: Sets the 802.1p priority. The pre-value argument is in the range 0 to 7.
You can also provide one of the keywords listed in Table 1-10 for the pre-value argument. The
