SNMP V1 and SNMPV2C adopt the community name authentication scheme.
■
SNMP Community is named with a character string, which is called community
name. SNMP community name defines the relationship between SNMP
manager and SNMP agent. The community name functions like a password,
that is, it controls the access of the SNMP manager to the SNMP agent. You
can choose to specify one or more community name-related features: Define
MIB views of all the accessible MIB subsets.
Define the read-only or read-write access mode of the community name to the
■
MIB. The community with read-only authority can only query the device
information, whereas the community with read-write authority can also
configure the device.
Perform the following configuration in system view.

System information includes the ID and the contact method of the administrator,
the location of the switch and the version of the SNMP.
The ID and the contact method of the administrator is a character string describing
the contact information used for the system maintenance. Through this
information, the device maintenance staffs can obtain the manufacturer
information of the device so as to contact the manufacturer in case the device is in
trouble. You can use the following command to set the contact information.
The location information of the switch is a management variable of the system
group in MIB, which represents the location of the managed device.
Perform the following configuration in system view.
