SNMP Version 3
SNMP version 3 (SNMPv3) is an enhanced version of the Simple Network
Management Protocol, approved by the Internet Engineering Steering Group in
March, 2002. SNMPv3 contains additional security and authentication features that
provide data origin authentication, data integrity checks, timeliness indicators and
encryption to protect against threats such as masquerade, modification of
information, message stream modification and disclosure.
SNMPv3 allows clients to query the MIBs securely.
SNMPv3 configuration is managed using the following command path:
For more information on SNMP MIBs and the commands used to configure SNMP
on the switch, see the Enterprise NOS 8.4 Command Reference .
Default Configuration
Enterprise NOS has four SNMPv3 users by default. All the four users have access
to all the MIBs supported by the switch:
 User 1 name is
adminmd5
(password
adminmd5
). The authentication used is
MD5; the privacy protocol used is DES.
 User 2 name is
adminsha
(password
adminsha
). The authentication used is
SHA; the privacy protocol used is DES.
 User 3 name is
mmv3_mgr
(password
mmv3_mgr
). The authentication used is
MD5; the privacy protocol used is DES. User 3 with the default password is used
for EHCM level 1 access. For EHCM level 2 and level 3 access, the CMM
generates a random password. EHCM level 2 uses MD5 authentication and DES
privacy protocol. EHCM level 3 uses SHA authentication and AES ‐ 128 privacy
protocol
 User 4 name is
adminshaaes
(password
Edpq132x!#9Zpx432w
).
Authentication used is SHA. Privacy protocol used is AES ‐ 128.
In boot strict mode (See “Boot Strict Mode” on page 52 ), Enterprise NOS has two
SNMPv3 users:
 User 1 name is
mmv3_mgr
(password
mmv3_mgr
). Authentication used is SHA.
Privacy protocol used is AES ‐ 128.
 User 2 name is
adminshaaes
(password
Edpq132x!#9Zpx432w
).
Authentication used is SHA. Privacy protocol used is AES ‐ 128.
Up to 17 SNMP users can be configured on the switch. To modify an SNMP user,
enter the following commands:
CN 4093(config)# snmp-server ?
CN 4093(config)# snmp-server user
<1 ‐ 17>
name
<1 ‐ 32 characters>
