How to Use the snmp and windows7snmp commands on Windows 7

How can I enable the snmp service by using commands when the device has installed snmp?
First, we need to know what device you are talking about?
If you enable the SNMP service for a WINDOWS Device in the service, you can configure it in the function.
For linix unix devices, we need to download the appropriate NET-SNMPD package and configure the relevant information in the SNMPD-CONFIGURE file.
For a hardware device, we need the corresponding MIB for SNMP monitoring.
How to Set snmp in command-based linux
1) install SNMP
For more information, see how to install SNMP in LINUX. Generally, the SNMP service is automatically installed in Linux. Run the following command to check whether the SNMP service is installed and whether the package is installed.
[Root @ idc ~] # Rpm-qa | grep snmp
Net-snmp-libs-5.1.2-11.EL4.7
Net-snmp-5.1.2-11.EL4.7
2) Configure SNMP
Modify the/etc/snmp/snmpd. conf file as follows:
A. Modify the default community string (SNMP read value password in SUM)
Com2sec notConfigUser default public
Modify public to a string that you only know
Change "default" to the machine you want to view your snmp information. For example, if the IP address of SUM is 10.10.10.10, change it to this IP address. If this parameter is left blank, it indicates that all machines are sufficient.
B. Remove the # below
# View mib2 shortded .iso.org. dod. internet. mgmt. mib-2 fc
To enable all functions, you can use the following line (if not, you can add one line ):
View all supported ded. 1 80
C. Run the following statement
Access notConfigGroup "" any noauth exact systemview none
Changed:
Access notConfigGroup "" any noauth exact mib2 none
Or:
Access notConfigGroup "" any noauth exact all none
3) Start and Stop SNMP
Generally, use the service snmpd start | stop | restart command. Or:
#/Etc/rc. d/init. d/snmpd restart
4) Firewall
If the firewall is enabled in Linux, open the UDP port 161. Ensure that the Linux iptables firewall has enabled udp port 161 access to the SUM monitoring server.
