A community string is just that - a string of characters! Do you mean how the strings are configured on a specific device, as the configuration steps are different depending on the device you are working with? There is also the question on which version to use.
Could you give a bit more details on what you are looking to achieve?
in defining a node there i a part wherein we will input the read/write community string:____________
what do we usually input in there?
certainly i nee to know how the strings are configured on a specific device
is the strings are configured on a specific device = enabling SNMP ??
I hope you are not going to set a Read/Write community string without using SNMP v3 (encryption and authentication capable). Windows systems are not capable of SNMP v3. Most network devices and unix systems can use v3. SNMP v1 and v2 are not encrypted. You would be sending a "String" (password) across the network in plain text. This password would have write capability to the configuration of your IBM server. Set a Read Only string if possible.
i have created SNMPv1.. i did not create read/write community string. i can now see some interface on my netflow source and a node from top10 netflow sources by percent utilization..however my endpoint,application.conversation are still blank
i have IBM v7000 storage connected to a sanswitch.. how do i enable SNMP on it? the V7000 storewise has no snmp enable on its gui.. will i use the cli on the sanswitch to enable its snmp?
A quick google found this:
This looks like traps though rather than SNMP GET. This is common, as some storage vendors prefer you to use their own monitoring tools, so don't support SNMP queries
The strings are configured in different places, depending on the device. If the device has a web config portal, it will be setup somewhere there, or on a cisco device for example, it is configured in the cli.
What is the specific device you are working with?
On a windows server you must have the SNMP service installed and running. The community string is configured on the security tab of the SNMP Service Properties window.
The sting you configure here must be the same as the string you configure on the NPM server.
