Thanks for reporting. I've confirmed leo_storage, leo_gateway and leo_manager, then recognized leo_manager does not support that yet:

• leo_gateway:
  • leo_gateway.con
  • leo_gateway.schema
• leo_storage:
  • leo_storage.conf
  • leo_storage.schema

We can set smp mode as below:

• "smp enable"

-config ./snmp/snmpa_manager_0/leo_manager_snmp
-smp enable
-env ERL_MAX_ETS_TABLES 256000
-env ERL_CRASH_DUMP ./log/erl_crash.dump
-env ERL_FULLSWEEP_AFTER 0
-env ERL_MAX_PORTS 64000
+A 32
+K true
-setcookie 401321b4
-name manager_0@127.0.0.1
+P 1048576

• "smp disable"

-config ./snmp/snmpa_manager_0/leo_manager_snmp
-smp disable
-env ERL_MAX_ETS_TABLES 256000
-env ERL_CRASH_DUMP ./log/erl_crash.dump
-env ERL_FULLSWEEP_AFTER 0
-env ERL_MAX_PORTS 64000
+A 32
+K true
-setcookie 401321b4
-name manager_0@127.0.0.1
