Step 8 (Optional) Run:
snmp-agent sys-info { contact contact | location location }
The equipment administrator's contact information or location is configured.
This step is required when the NM station administrator must know equipment administrators'
contact information and locations when the NM station manages many devices. This allows the
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.

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 02 (2012-03-30)
mirroring is configured to prevent a well-known port from being attacked), the parameter
udp-port can be used to specify a non-well-known UDP port number. This ensures normal
communication between the NM station and managed device.
public network, the parameter public-net needs to be configured. If the alarms sent from the
managed device to the NM station need to be transmitted over a private network, the
parameter vpn-instance vpn-instance-name needs to be used to specify a VPN that will take
over the sending task.
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
