Multiple “Community name” and the matching “Trap destinations” can be defined using the Traps tab in the SNMP service. Each community name exists in its own key (node) under:
within which one or more trap destinations are stored as properties (REG_SZ) in this registry location.
For example, you need to add a new community name and a host as the trap destination. This can be achieved as follows:
$communityName = "CommunityName01"
$serverName = "FS01"
$registryPath = "HKLM:\System\CurrentControlSet\Services\SNMP\Parameters\TrapConfiguration"
# create community name if not exists
if (-not (Test-Path "$registryPath\$communityName"))
New-Item -Name $communityName -Path $registryPath
# get current number of trap destinations and increase by 1 to add as new item
$i = (Get-ItemProperty "$registryPath\$communityName" | Measure).count
New-ItemProperty -Name $i -Value $serverName -Path "$registryPath\$communityName"
A manual check is as simple as below:
Similarly, removal of the registry key and properties is carried out as such:
#remove community name and associated trap destinations
