Setting Community
Name
SNMP V1 and SNMPV2C adopt the community name authentication scheme. The
SNMP message incompliant with the community name accepted by the device will
be discarded. SNMP Community is named with a character string, which is called
Community Name. The various communities can have read-only or read-write
access mode. The community with read-only authority can only query the device
information, whereas the community with read-write authority can also configure
the device.
You can use the following commands to set the community name.
Perform the following configuration in System View.
