Comtech EF Data SLM-5650A Installation And Operation Manual page 167

Notes:
1. Although the customer can choose the security model used, there is no
choice on the encryption method – data is always encrypted using the
DESC scheme.
2. The User Name and Password defined here are the ones used in an
SNMP client, and are separate from the user name/password used to
access the SLM-5650A HTTP/HTTPS/Telnet interfaces.
3. It is not necessary to change the Engine ID to have an acceptable level
of encryption. However, you should note that changing the Engine ID
does affect the generation of authentication keys.
