The system allows the sharing of a single meter for both unicast and multipoint traffic. The user can configure any of the available meters for multipoint traffic. The use of the multipoint keyword during meter creation is deprecated, except for use with meter 11 as described in the following paragraphs.
When the multipoint keyword is specified with meter 11 the software interprets it to be the default multipoint meter. The default multipoint meter is used for all FCs that do not have explicit multipoint meters configured.The software performs resource checks to ensure that resources needed to use the multipoint meter with all the FCs are available before allowing this change.
When the num-qos-resources command is set to a value of 2, the default multipoint meter 11 cannot be used because only a single meter is available for use.
When associating a meter with an FC for BUM traffic, the software does not validate whether the meter is a multipoint meter, which allows the user to use a single meter for unicast and BUM traffic. This implies efficient use of SAP ingress qos resources. From Release 4.0R4 onwards when the multipoint keyword is used, the software issues a warning indicating that it is an obsolete CLI command, and it is not saved in the configuration file, deprecating the use of multipoint keyword with any meter other than the default.
