Overview of service ingress policy on 7210 SAS-K
Use of the keyword "multipoint" for default meter "11"
The system allows 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 '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 does the appropriate resource checks to ensure that
resources needed to use multipoint meter with all the FCs are available before allowing this
change.
Note 1: When num-qos-resources is set to a value of '2', default multipoint meter "11" cannot be
used as only a single meter is available for use.
Note 2: When associating a meter with a FC for BUM traffic, the software does not validate if the
meter is a multipoint meter thus allowing 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, software throws 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.
Examples of usage of multipoint meter:
Example 1:
*7210-SAS>config>qos# sap-ingress 12 create
*7210-SAS>config>qos>sap-ingress$ info
----------------------------------------------
----------------------------------------------
*7210-SAS>config>qos>sap-ingress$
All FCs in the SAP ingress policy use the default meter 1 (for all traffic types). If the command
"configure qos sap-ingress <id> meter 11 multipoint create" is executed, it attaches the default
meter "11" with all the FCs defined in the SAP ingress policy.
After this configuration, all the FCs in this policy use two meters, default meter "1" to meter
unicast traffic for all the FCs and meter "11" to meter BUM traffic for all the FCs. In this specific
example, since only default FC "be" is in use, the multipoint meter will be used to meter BUM
traffic associated with default FC "be".
