Encryption (DES), the USM User Table, and View-Based Access (refer
to RFC2574 for full details). The SNMP Agent has limited SNMPv3
support in the following areas:
• Only MD5 Authentication is supported (no SHA-1). SNMPv3
provides support for MD5 and SHA-1.
• Limited USM User Table Manipulation. The SNMP Agent
starts with 5 default accounts. New accounts can be added
(SNMPv3 adds new accounts by cloning existing ones), but
they will be volatile (will not survive a power-cycle).
New views cannot be configured on the SNMP Agent. Views are
inherited for new accounts from the account that was cloned.
The SNMP Agent uses one password pair (Authentication/Pri-
vacy) for all accounts. This means that when the passwords
change for one user, they change for all users.
SNMPv3 Accounts
The following default accounts are available for the SNMP Agent:
enc_mdsadmin
—Read/write account using Authentication and Encryp-
tion.
auth_mdsadmin
—Read/write account using Authentication.
enc_mdsviewer
—Read only account using Authentication and Encryp-
tion.
auth_mdsviewer
—Read only account using Authentication.
def_mdsviewer
—Read only account with no Authentication or Encryp-
tion.
Context Names
The following Context Names are used (refer to RFC2574 for full
details):
Admin accounts:
context_a
/Viewer accounts:
context_v
.
All accounts share the same default passwords:
Authentication default password:
MDSAuthPwd
/Privacy default pass-
word:
MDSPrivPwd
.
Passwords can be changed either locally (via the console) or from an
SNMP Manager, depending on how the Agent is configured. If pass-
words are configured and managed locally, they are non-volatile and
will survive a power-cycle. If passwords are configured from an SNMP
manager, they will be reset to whatever has been stored for local man-
agement on power-cycle.
