Verify Agent Response to Queries

Use the sysvariable utility to query a system and prove that the agent is responding to queries. You must specify the port number (unless you are using the default port of 161) for the agent and the community string for your system if the agent is configured to accept SNMPv1 or SNMPv2c communication. Otherwise, you must specify all necessary SNMPv3 communication (depending on the security level - Authpasswd, Authprotocol, Privpasswd, Privprotocol).

To display the operating system release number for a UNIX system where the agent is on port 1691 and the community string is public, enter the following for SNMPv1:

#./sysvariable -h 127.0.0.1 -p 1691 -c public -v 1 -o systype

To display the operating system release number for a UNIX system where the agent is on port 1691 and the community string is public, enter the following for SNMPv2c:

#./sysvariable -h 127.0.0.1 -p 1691 -c public  -v 2c -o systype

To display the operating system release number for a UNIX system where the agent is on port 1691 and the SecLevel is configured to AuthPriv(3) with secuser as the USM user name, authpasswd as the Authentication password, MD5 as the Authentication protocol, privpasswd as the Privacy password and DES as the Privacy protocol, enter the following for SNMPv3:

#./sysvariable -h 127.0.0.1 -p 1691 -v 3 -u secuser -s 3 -a authpasswd -A MD5 -x privpasswd -X DES -o systype

For a Windows system where the agent is on port 1691 and the community string is public, enter the following for SNMPv1:

C:\sysedge\bin>sysvariable.exe -h 127.0.0.1 -p 1691 -c public -v 1 -o systype

For a Windows system where the agent is on port 1691 and the community string is public, enter the following for SNMPv2c:

C:\sysedge\bin>sysvariable.exe  -h 127.0.0.1 -p 1691 -c public  -v 2c -o systype

For a Windows system where the agent is on port 1691 and the SecLevel is configured to AuthPriv(3) with secuser as the USM user name, authpasswd as the Authentication password, MD5 as the Authentication protocol, privpasswd as the Privacy password and DES as the Privacy protocol, enter the following for SNMPv3:

C:\sysedge\bin>sysvariable.exe  -h 127.0.0.1 -p 1691 -v 3 -u secuser -s 3 -a authpasswd -A MD5 -x privpasswd -X DES -o systype
