◆
An SNMP engine is an independent SNMP agent that resides either on
this switch or on a remote device. This engine protects against
message replay, delay, and redirection. The engine ID is also used in
combination with user passwords to generate the security keys for
authenticating and encrypting SNMPv3 packets.
◆
A remote engine ID is required when using SNMPv3 informs. (See the
snmp-server host command.) The remote engine ID is used to compute
the security digest for authentication and encryption of packets passed
between the switch and 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.
◆
Trailing zeroes need not be entered to uniquely specify a engine ID. In
other words, the value “0123456789” is equivalent to “0123456789”
followed by 16 zeroes for a local engine ID.
◆
A local engine ID is automatically generated that is unique to the
switch. This is referred to as the default engine ID. If the local engine
ID is deleted or changed, all SNMP users will be cleared. You will need
to reconfigure all existing users ( page 693 ).
