engineid-string - String identifying the engine ID.

address.
Command Mode
Global Configuration
Command Usage
• An SNMP engine is an independent SNMP agent that resides on this switch.
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.
• Trailing zeroes need not be entered to uniquely specify a engine ID. In other
words, the value “1234” is equivalent to “1234” followed by 22 zeroes.
• 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 4-124).
