I used Cygwin with snmp tools and here the result

snmpset -v 2c -c myCommunity myIP Dell-LAN-SYSMNG-MIB::dellLanFileActionCommand.1 i 2 Dell-LAN-SYSMNG-MIB::dellLanFileActionSourceFile.1 s 'running-config' Dell-LAN-SYSMNG-MIB::dellLanFileActionDestFile.1 s 'startup-config'
Error in packet.
Reason: noCreation (That table does not support row creation or that object can not ever be created)
Failed object: Dell-LAN-SYSMNG-MIB::dellLanFileActionCommand.1

I think I found the solution

So, if I'm reading it correctly, an SNMP SET-based "write mem" operation
might look something like this shell script:

  ip=X.X.X.X
  community=XXX

  snmpset -c $community $ip \
    Dell-LAN-SYSMNG-MIB::dellLanFileActionCommand.1 i 2 \
    Dell-LAN-SYSMNG-MIB::dellLanFileActionSourceFile.1 s 'running-config' \
    Dell-LAN-SYSMNG-MIB::dellLanFileActionDestFile.1 s 'startup-config'

Are you able to make that work?
