•A remote engine ID is required when using SNMPv3 informs. (See snmp-server host on page 4-104.)The remote engine ID is used to compute the security digest for authenticating and encrypting packets sent to a user on the remote host.

You therefore need to configure the remote agent’s SNMP engine ID before you can send proxy requests or informs to it.
