T3700G-52TQ JetStream 52-Port Gigabit Stackable L3 Managed Switch CLI Guide local | remote -- User Type, with local and remote options. Local indicates that the user is connected to a local SNMP engine, while remote indicates that the user is connected to a remote SNMP engine. cmode -- The Authentication Mode of the SNMP v3 User, with "none", "MD5" and "SHA" options. "None" indicates no authentication method is used, "MD5" indicates the port authentication is performed via HMAC-MD5 algorithm and "SHA" indicates the port authentication is performed via SHA (Secure Hash Algorithm). SHA authentication mode has a higher security than MD5 mode. By default, the Authentication Mode is "none". confirm-pwd -- Authentication Password, ranging from 1 to 16 characters. The question marks and spaces are not allowed. This password in the configuration file will be displayed in the symmetric encrypted form. emode -- The Privacy Mode of the SNMP v3 User, with "none" and "DES" options. "None" indicates no privacy method is used, and "DES" indicates DES encryption method is used. By default, the Privacy Mode is none. encrypt-pwd -- Privacy Password, ranging from 1 to 16 characters. The question marks and spaces are not allowed. This password in the configuration file will be displayed in the symmetric encrypted form. Command Mode Global Configuration Mode Example Add Local User admin to Group group2, and configure the Authentication Mode of the user as MD5, the Authentication Password as 11111, the Privacy Mode as DES, and the Privacy Password as 22222: T3700G-52TQ(config)#snmp-server user admin group2 local cmode MD5 cpwd 11111 emode DES epwd 22222 35.4 snmp-server community Description The snmp-server community command is used to add Community. To delete the corresponding Community, please use no snmp-server community command. SNMP v1 and SNMP v2c adopt community name authentication. The community name can limit access to the SNMP agent from SNMP network management station, functioning as a password. 293
