For information about SRRP, see the 7450 ESS, 7750 SR, and VSR Triple Play Service Delivery Architecture Guide.
In the context of an ESM SRRP deployment, the operator can define at the app-profile level if the subscriber is diverted to the ISA-AA card per SRRP group interface. This can be useful to reduce the total number of ISA cards required in the event of a switch-over from a primary to backup SRRP node when AA is used as a value-add service for selected subscribers.
To configure the network for suppressible app-profiles in the context of SRRP the operator needs to:
Enable the capability to suppress AA subscribers on a specific SRRP group interface, typically by selecting backup SRRP group interfaces.
ESM subscribers with a valid app-profile are diverted to AA by default, to suppress selected group of subscribers using AA for optional value-add services. The operator then specifies which app-profile is suppressed and therefore not diverted to AA.
Use the following CLI syntax to enable the capability to suppress ESM subscribers from a backup SRRP group interface:
config>service>vprn>sub-if>grp-if# suppress-aa-sub [create]
characteristic characteristic-name value value-name
description description-string
[no] aa-sub-suppressible
divert
The following example displays an application profile configuration used for premium subscribers, this type of subscriber is always be diverted to Application Assurance, it is also the default configuration:
7750>config>app-assure>group>policy# info
----------------------------------------------
app-profile "Premium" create
characteristic "Parental-Control" eq "Yes"
divert
exit
----------------------------------------------
The following example displays an application profile configuration for best effort / value-add subscribers not diverted to Application Assurance on the SRRP group interface configured with ‟suppress-aa-sub”:
7750>config>app-assure>group>policy# info
----------------------------------------------
app-profile "1-default" create
divert
aa-sub-suppressible
exit
----------------------------------------------
