Specifying a Remote Engine ID

To send inform messages to an SNMPv3 user on a remote device, you must first
specify the engine identifier for the SNMP agent on the remote device where the
user resides. The remote engine ID is used to compute the security digest for
authenticating and encrypting packets sent to a user on the remote host.
SNMP passwords are localized using the engine ID of the authoritative agent. For
informs, the authoritative SNMP agent is the remote agent. You therefore need to
configure the remote agent’s SNMP engine ID before you can send proxy requests
or informs to it. (See "Specifying Trap Managers and Trap Types" on page 3-40 and
"Configuring Remote SNMPv3 Users" on page 3-47.)
A new engine ID can be specified by entering 10 to 64 hexadecimal characters.
