Step 7 (Optional) Run:
snmp-agent packet max-size byte-count
The maximum size of an SNMP packet that the device can receive or send is set.
By default, the maximum size of an SNMP packet that the device can receive or send is 12000
bytes.
After the maximum size is set, the device will discard any SNMP packet that is larger than the
set size. The allowable maximum size of an SNMP packet for a device depends on the size of a
packet that the NM station can process; otherwise, the NM station cannot process the SNMP
packets sent from the device.

Follow-up Procedure
After the configurations are complete, basic communication can be conducted between the NM
station and managed device.

1.3.3 (Optional) Controlling the NM Station's Access to the Device

This section describes how to specify an NM station and manageable MIB objects for SNMP-
based communication between the NM station and managed device to improve communication
security.
Context
If a device is managed by multiple NM stations that use the same community name, note the
following points:
l
l
Issue 01 (2012-03-15)
Access control allows any NM station that uses the community name to monitor and manage
all the objects on the managed device.
The managed device sends alarms generated by the modules that are open by default to the
NM station.
To allow a specified NM station that uses the community name to manage specified objects
of the device, follow the procedure described in
the Device.
To allow a specified module on the managed device to report alarms to the NM station,
follow the procedure described in
Function.
If the NM station and managed device are both Huawei products, follow the procedure
described in Enabling the SNMP Extended Error Code Function
send more types of error codes. This allows more specific error identification and facilitates
your fault location and rectification.
If all the NM stations that use the community name need to have rights to access the objects
in the Viewdefault view (1.3.6.1), skip the following steps.
If some of the NM stations that use the community name need to have rights to access the
objects in the Viewdefault view (1.3.6.1), skip Step5.
