How many max link can we configure in a LAG of MX960 (junos version 21.2R3.8)

https://apps.juniper.net/feature-explorer/select-platform.html?typ=1&category=Routing&pid=11310960&platform=MX960&swName=Junos%20OS&rel=21.2R3&sid=1211&swtab=Junos%20OS"

The maximum links by default can be set to 16. If needed we can even set it to higher values. Verified this on a lab device as well.

lab@mx960-re0# set chassis aggregated-devices maximum-links ?

Possible completions:

 <maximum-links>   Maximum links limit for aggregated devices (16, 32, or 64)

Note that for MX Series routers, to set a range of 32 or 64 the router must be running in Enhanced IP mode

We get the below error when trying to set the value to 32:

[edit]

 'chassis'

  MX must be configured with enhanced-ip or enhanced-ethernet to set aggregated-devices maximum-links to 32
