DELL CONFIDENTIAL – PRELIMINARY 5/15/12 – FOR PROOF ONLY
• Changing the value of the engine ID has the following important side-effect. A user's password
(entered on the command line) is converted to an MD5 or SHA security digest. This digest is
based on both the password and the local engine ID. The user’s command line password is then
destroyed, as required by RFC 2274. As a result, the security digests of SNMPv3 users become
invalid if the local value of the engine ID change, and the users will have to be reconfigured.
• You cannot specify an engine ID that consists of all 0x0, all 0xF or 0x000000001.
•The
show running-config Privileged EXEC mode command does not display the SNMP engine
ID configuration. To see the SNMP engine ID configuration, enter the

local
