hexadecimal characters and then click Save.
Figure 5-4 Setting the SNMPv3 Engine ID
CLI – This example sets an SNMPv3 engine ID.
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 5-6 and “Configuring Remote
SNMPv3 Users” on page 5-15.)
The engine ID can be specified by entering 10 to 64 hexadecimal
characters. If less than 64 characters are specified, trailing zeroes are added
to the value. For example, the value “0123456789” is equivalent to
“0123456789” followed by 60 zeroes.
