Description This command configures the amount of ingress internal CAM resources available in the SF/
CPM for use by G8032 fast-flood mechanism. These are used to implement G8032 fast-flood
for data services protected using G8032 ring protection mechanism. The amount of slices
determines the amount of data services that can be protected by G8032 and use the fast-
flood mechanism to reduce the convergence time on a ring failure and switchover.
The difference between resource usage on IMMv1 and IMMv2 is described as follows.
• On IMMv1, resources are used to implement the G8032 fast-flood mechanism for both
VPLS services and RVPLS services.
• On IMMv2, resources are used to implement the G8032 fast-flood mechanism for only
RVPLS services. These resources are used only if G8032 is enabled for RVPLS
services. The G8032 fast-flood mechanism is also implemented for VPLS services, but
no user configuration is required and it does not need resources to be allocated from the
sf-ingress-internal-tcam pool.
Parameters max_slice — Specifies the number of slices to be allocated for the G8032 fast-flood
mechanism. Each slice has many resource entries that are used to implement G8032
fast flood for multiple data services protected by G8032.

Description This command allows the user to configure the resources to be used for NG-MVPN P2MP
LSPs. The users must allocate some resources using the command before configuring NG-
MVPN. It might be necessary to free up resources allocated to other features to allocate
resources for it.
On 7210 SAS-R6, the number of resources per slice/chunk varies. Hence, the number of
resources allocated to a feature varies based on the order of allocation of resources among
different features. It might be necessary to allocate more slices to a feature to achieve desired
scaling.
The no form of this command does not allocate any resources for use by P2MP LSPs used
with NG-MVPN feature. If no resources are allocated for use, the software will not be able to
setup P2MP LSPs for use with NG-MVPN.
Parameters max_slice — Specifies the number of slices to be allocated for NG-MVPN P2MP LSPs.
Values 0 to 3
Default 1
