Tip In the following steps, source and destination addresses are given by source-ip and
destination-ip, along with masks for wildcard matching (0-bit matches, 1-bit is wildcard). If
any address is to be matched, you can replace the address and mask fields with the key-
word any. If a specific host address is to be matched, you can replace the address and mask
fields with the keyword host followed by its IP address.
(global) mls qos map policed-dscp internal-dscp to policed-dscp
The internal DSCP values internal-dscp are marked down to policed-dscp val-
ues. Internal DSCP values can be specified as single values, multiple values sepa-
rated by commas, or as a hyphenated range. A COS switch requires a colon (:)
between the internal and policed DSCP values, whereas an IOS switch requires
the to keyword. More mappings can be given on a COS switch by separating
them with spaces, and on an IOS switch by repeating this command.
