Huawei AR150/200 Series, Configuration Manual

Page: 16 / 274

The AR150/200 supports SNMPv1, SNMPv2c, and SNMPv3. Table 1-2 lists the features
supported by SNMP, and Table 1-3 shows the support of different SNMP versions for the
features. Table 1-4 describes the usage scenarios of SNMP versions, which will help you choose
a proper version for the communication between an NM station and managed devices based on
the network operation conditions.
NOTE
When multiple NM stations using different SNMP versions manage the same device in a network,
SNMPv1, SNMPv2c, and SNMPv3 can all be configured on the device for its communication with all the
NM stations.
Table 1-2 Description of features supported by SNMP
Feature Description
Access control Restricts a user's device administration rights.
It gives specific users the rights to manage
specified objects on devices and therefore
provides fine management.
Authentication and encryption Authenticates and encrypts the packets
transmitted between the NM station and
managed devices. This prevents data packets
from being intercepted or modified,
improving data sending security.
Error code Identifies particular faults. An administrator
uses error codes to quickly locate and rectify
faults. The more error codes received, the
more they help an administrator in device
management.
Trap Sent from managed devices to the NM
station. These traps allow an administrator to
discover device faults immediately.
After sending traps, the managed devices do
not require the acknowledgement from the
NM station.
GetBulk Allows an administrator to perform GetNext
operation in batches. In a large-scale network,
GetBulk reduces the administrator's
workload and improves management
efficiency.
