To meet flexible scaling requirements in common compute platforms, operators can use the CLI to select VSR-NAT scaling profiles that correspond to the amount of memory allocated in the VM.
The following scaling profiles have predefined upper scaling limits and are available for VSR-NAT and IPv6 FW:
profile1 is a lower scaling profile.
profile2 is a higher scaling profile.
The default scaling profile is profile1.
Contact your Nokia representative for more information about NAT scaling figures in each profile.
For the number of required CPU control cores on a VSR-I in relation to profiles, see to the Sysinfo section in the Virtualized Service Router Installation and Setup Guide.
For the amount of required memory on VSR-I in relation to profiles, see Software Release Notes, section VM Memory Requirements by Function Mix.
Scaling profiles are applied under the following CLI hierarchy:
Classic CLI
*A:cses-V22# configure isa
*A:cses-V22>config>isa# nat-group 1 create
*A:cses-V22>config>isa>nat-group# scaling-profile
- scaling-profile <scaling-profile-id>
<scaling-profile-id> : {profile1|profile2}
MD-CLI
*[pr:/configure isa nat-group 1]
A:admin@cses-V27# scaling-profile ?
scaling-profile <keyword>
<keyword> - {profile1|profile2}
Default - profile1

'configure isa nat-group 1 admin-state' automatically for the new value to
take effect.
Warning: Modifying this element clears ISA state, such as flow state, for
the new value to take effect.
