MCAC interface policies

Overview

An operator can configure one or more MCAC (Multicast CAC) interface policies under a global MCAC context to prioritize and limit the mandatory and unconstraint bandwidth values across the supported interfaces in one or more VPRN/EIS services via a Global Route Table (GRT).

When a single MCAC interface policy is used by multiple interfaces in the network, channel admittance on one interface impacts the available bandwidth on all interfaces that share the same MCAC interface policy. Changing policy values behaves the same way as if the change to mandatory or unconstrained bandwidth was applied on an interface level.

If a MCAC interface policies is deployed together with per interface unconstrained and mandatory bandwidth constraints, a given multicast group must satisfy the MCAC conditions defined by the MCAC interface policy and by the interface to be admitted. If ESM is deployed on an interface and per-subscriber MCAC is enabled, then the per-subscriber MCAC must also be satisfied.

You can configure MCAC interface policies on 7x50 devices; this policy type can be associated with the following object/interface/policy types:

• VPLS SAP

• VPLS Spoke SDP and MVPL Spoke SDP

• IGMP Interface on base router and VPRN service

• MLD Interface on base router and VPRN service

• PIM Interface on base router and VPRN service

• IGMP Group Interface on IES and VPRN services

• MLD Group Interface on IES and VPRN services

• MSAP policy
