Information
Changing the value of the SNMP Engine ID has important side effects. A user's password (entered on
the command line) is converted to an MD5 (Message Digest Algorithm) or SHA (Secure Hash
Algorithm) security digest. This digest is based on both the password and the local Engine ID. The
command line password is then destroyed, as required by RFC 2274. Because of this deletion, if the
local value of the Engine ID changes, the security digests of SNMPv3 users will be invalid, and the
users will have to be reconfigured.
For the remote Engine ID, the host IP and UDP port are the indexes to the command that are matched
to either overwrite or remove the configuration.
