Description You can establish a CARL based on IP precedence, dscp or MAC address.
For different carl-index, the repeat execution of this command will create multiple
CARLs, and for the same
carl-index, such undertaking will modify the parameters
of the CARL.
You can define eight precedence values at most. If the same precedence is specified
for several times, the system by default regards that only one precedence value has
been specified. The precedence values are related to one another in the way of “OR”.
