CN4093 Application Guide for N/OS 8.2
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:
CN4093(config)# snmpserver ?
For more information on SNMP MIBs and the commands used to configure SNMP
on the switch, see the Lenovo N/OS 8.2 Command Reference.
Lenovo N/OS 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). Authentication used is MD5.
Privacy protocol used is DES.
User 2 name is adminsha (password adminsha). Authentication used is SHA.
Privacy protocol used is DES.
User 3 name is mmv3_mgr (password mmv3_mgr). Authentication used is MD5.
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 pro‐
tocol. EHCM level 3 uses SHA authentication and AES‐128 privacy protocol
User 4 name is adminshaaes (password Edpq132x!#9Zpx432w). Authentica‐
tion used is SHA. Privacy protocol used is AES‐128.
In boot strict mode (See "Boot Strict Mode" on page
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). Authentica‐
tion used is SHA. Privacy protocol used is AES‐128.
