After SNMPv1 is enabled on the managed device, the device supports both SNMPv1 and
SNMPv3. This means that the device can be monitored and managed by NM stations running
SNMPv1 or SNMPv3.
Step 4
Run:
snmp-agent community
{
read
|
write
} {
community-name
|
cipher
community-name1
}
[
acl
acl-number
|
mib-view
view-name
]
*
The community name is set.
After the community name is set, if no MIB view is configured, the NM station that uses the
community name has rights to access objects in the Viewdefault view (1.3.6.1).
l
read
: NM station administrator configures the
read
parameter to provide read access to the
low level administrator for a specified view.
l
write
: NM station administrator configures the
write
parameter to provide read and write
access to the low level administrator for a specified view.
Step 5
Choose either of the following commands as needed to configure a destination IP address for
the alarms and error codes sent from the device.
l
To configure a destination IPv4 address for the alarms and error codes sent from the device,
run:
snmp-agent target-host trap
address
udp-domain
ip-address
[
udp-port
port-
number
] [
vpn-instance
vpn-instance-name
]
params
securityname
security-name
[
v1
] [
private-netmanager
]
l
To configure a destination IPv6 address for the alarms and error codes sent from the device,
run:
snmp-agent target-host trap
ipv6
{
address
udp-domain
ipv6-address
} [
udp-port
port-number
]
params
securityname
security-name
[
v1
]
The descriptions of the command parameters are as follows:
l
udp-port
: The default UDP port number is 162. In some special cases (for example, port
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
communication between the NM station and managed device.
l
vpn-instance
: 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 takes over the sending task.
l
securityname
: Identifies the alarm sender, which helps you learn the alarm source.
Step 6
(Optional) Run:
snmp-agent sys-info
{
contact
contact
|
location
location
}
The equipment administrators contact information or location is configured.
This step is required for the NMS administrator to view contact information and locations of the
equipment administrator when the NM station manages many devices. This helps the NMS
administrator to contact the equipment administrators for fault location and rectification.
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 1500
bytes.
