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.
