NM station administrator to contact the equipment administrators quickly for fault location and
rectification.
To configure both the equipment administrator's contact information and location, you must run
the command twice to configure them separately.
Step 8 (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

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

This section describes how to specify an NM station and manageable MIB objects for SNMPv3-
based communication between the NM station and managed device to improve communication
security.
Context
If a device is managed by multiple NM stations that are in the same SNMPv3 user group, note
the following points:
Issue 01 (2012-03-15)
Access control allows any NM station in the configured SNMPv3 user group 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 in an SNMPv3 user group to manage specified objects of
the device(such as NM station with the specified IP address), follow the procedure
described in Controlling the NM Station's Access to the
To allow a specified module on the managed device to report alarms to the NM station,
follow the procedure described in
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.
