Test-VipReachability

Tests whether DIPs are reachable.

Syntax

Test-VipReachability
    [[-OperationId] <String>]
    [-SourceIP] <String>
    [[-CompartmentId] <String>]
    [-TargetVIP] <String>

    [[-SequenceNumber] <Int32>]
    [[-PayloadSize] <Int32>]
    [<CommonParameters>]

Description

The Test-VipReachability cmdlet tests whether a list of datacenter IP addresses (DIPs) can be reached through the specified multiplexers (MUXes).

The test covers layer-3 connectivity to the MUX nodes, and from the MUX nodes to the DIP hosts.

The test first sends Internet Control Message Protocol (ICMP) echo requests to the virtual IP (VIP) address. The MUX intercepts the echo requests and sends responses that appear to come from the targeted VIP.

The test then sends ICMP echo requests from the MUX host to the DIP host on the provider network. The results of the test are reported in the output object.

Examples

Example 1: Test VIP reachability

PS C:\> for ($mux in $VipHostMapping.MuxList) {
    $secpasswd = ConvertTo-SecureString <plaintext password> -AsPlainText -Force
    $creds = New-Object System.Management.Automation.PSCredential (<username>, $secpasswd)
    $mux.Credentials = $creds
}
PS C:\> for ($dip in $VipHostMapping.DIPHosts) {
    $secpasswd = ConvertTo-SecureString <plaintext password> -AsPlainText -Force
    $creds = New-Object System.Management.Automation.PSCredential (<username>, $secpasswd)
    $dip.HostInfo.Credentials = $creds
}
PS C:\> Test-VIPReachability -OperationId 1 -SourceIP "10.123.176.108" -TargetVIP "10.123.177.110" -Muxes $VipHostMapping.MuxList -Dips $VipHostMapping.DIPHosts

The first command populates the credentials for the MUX nodes to test.

The second command populates the credentials for the DIPs to test.

The last command tests the VIP reachability for the specified MUXes and DIPs.
