Setting the Community Name
Both SNMP V1 and SNMPV2C use the community name authentication scheme.
An SNMP message that does not comply with the community name that is
accepted by the device is discarded. An SNMP community is named with a
character string, which is called the community name. Communities can have
read-only or read-write access modes. A community with read-only authority can
only query the device information, whereas the community with read-write
authority can also configure the device.
Use the following commands to set the community name.
Perform the following configuration in system view.
