I should add that after the pager limit is exceeded, it simply disables the 
pager (if that does not work and it eats the output, please let me know!)

This is to limit memory consumption more than anything since it has to keep all 
the CLI output in memory to be able to paginate it. 100K lines was thought a 
reasonable default limit for this – at 80 characters per line this would be 
about 8MB+overhead and thus doesn’t put too much pressure on the heap. I would 
recommend you use vppctl and send the output to a file, or pipe to less, if you 
really do generate that much output.

Subject: [EXTERNAL] [vpp-dev] Pager Buffer limit

Hi,

I am working on creating a VPP cli which dumps a lot of info.

Is there any limitation to the number of lines we can print in a paged format 
using vlib_cli_output ? I am not able to print more than 100K lines.

Beyond that i get the error "-- pager buffer overflowed --" .
Also, how do I modify this limit ?

Thanks & Regards,
Siddarth
