Hello @Hasun Gunasekara,
If a platform doesn’t support MOP, then the commands to disable MOP won’t be visible in the command help and you will get an error if you try to configure it, as shown in the following examples:
Router(config)#interface gigabitEthernet 1
Router(config-if)#no mop ?
% Unrecognized command
Router(config-if)#no mop enabled
^
% Invalid input detected at '^' marker.
Router(config-if)#
To see if the software image on the platform you are running supports MOP, enter
the show subsys | include mop CLI command. If the platform supports MOP, it will show a line with mop Protocol, as shown in the following example:
Router#show subsys | include mop
mop Protocol 1.000.001
Router#
If the device doesn’t support MOP, it will return nothing as shown in the following example:
Router#show subsys | include mop
Router#
