[Sysname] snmp-agent usm-user v2c userv2c readCom
Specify the SNMP version of the NMS as SNMPv2c , fill the write community name field with userv2c .
Then the NMS can access the agent.
# Create an SNMPv2c user userv2c in group readCom , permitting only the NMS with an IP address
1.1.1.1 to access the agent, and denying the access of other NMSs.

Parameters
user-name : Username, a string of 1 to 32 characters.
group-name : Name of the group corresponding to the user, a string of 1 to 32 characters.
cipher : Specifies the authentication password ( auth-password ) or encryption password ( priv-password )
to be in cipher text. The cipher text password can be calculated using the snmp-agent
calculate-password command.
authentication-mode : Specifies the security mode as authentication required. If you do not specify this
keyword, neither authentication nor encryption is performed.
md5 : Uses HMAC MD5 algorithm for authentication.
sha : Uses HMAC SHA algorithm for authentication, which is securer than MD5.
auth-password : Authentication password, a string of 1 to 64 characters in plain text, a 32-bit
hexadecimal number in cipher text if MD5 algorithm is used, and a 40-bit hexadecimal number in cipher
text if SHA algorithm is used.
privacy : Specifies the security mode as encrypted.
des56 : Specifies the encryption protocol as Data Encryption Standard (DES).
aes128 : Specifies the encryption protocol as Advanced Encryption Standard (AES), which is securer
than DES.
