Is there SNMP MIBs that can be used to monitor CGNAT related stuff on CGSE and ISM modules.
Especially those values:
Number of sessions
Translations create rate
Translations delete rate
Inside to outside forward rate
Outside to inside forward rate
Inside to outside drops port limit exceeded
Inside to outside drops system limit reached
Inside to outside drops resource depletion
No translation entry drops
There is discussion going on internally. But, it has not been committed for any future release yet.
So, my suggestion would be to use an alternate method (via scripts) for the time being.
