Adding a custom SNMP OID means having a different "expression <value>" line each time the config is pulled. Add a rule to remove the expression value. EEM code to generate the custom SNMP OID is: event manager applet TotalNatTranslations event timer watchdog time 300 maxrun 60 action 010 cli command "enable" action 020 cli command "configure terminal" action 030 cli command "do-exec show ip nat translations total" action 040 regexp "^.+\s([0-9]+)" "$_cli_result" match total_translations action 050 cli command "snmp mib expression owner nat name 1" action 060 if $_regexp_result eq "1" action 070 cli command "expression $total_translations" action 080 else action 090 cli command "expression 0" action 100 cli command "exit" action 110 end The resulting configuration block is: snmp mib expression owner nat name 1 description Total active translations value type integer32 expression 1234 ! After this commit the resulting configuration block is: snmp mib expression owner nat name 1 description Total active translations value type integer32 expression <value removed> !
Slightly changed the configuration of C9200L => PR ytti#3299 works as intended.

Adding a custom SNMP OID means having a different "expression " line each time the config is pulled. Add a rule to remove the expression value.
EEM code to generate the custom SNMP OID is:
event manager applet TotalNatTranslations
event timer watchdog time 300 maxrun 60
action 010 cli command "enable"
action 020 cli command "configure terminal"
action 030 cli command "do-exec show ip nat translations total"
action 040 regexp "^.+\s([0-9]+)" "$_cli_result" match total_translations
action 050 cli command "snmp mib expression owner nat name 1"
action 060 if $_regexp_result eq "1"
action 070 cli command "expression $total_translations"
action 080 else
action 090 cli command "expression 0"
action 100 cli command "exit"
action 110 end
The resulting configuration block is:
snmp mib expression owner nat name 1
description Total active translations
value type integer32
expression 1234
!
After this commit the resulting configuration block is:
snmp mib expression owner nat name 1
description Total active translations
value type integer32
expression
!
