Pinging an IP address

Longer ping time

This is the same as above, with the -w variable changed to allow a 100ms reply window.

for /l %i in (1,1,254) do @ping 192.168.1.%i -w 100 -n 1 | find "Reply"

This will ping all addresses from 192.168.1.1 to 192.168.1.254 one time each, wait 100ms for a reply and show only the addresses that replied.

Continuous Ping

You can use Wndows PowerShell to create a continuous ping test.

Ping.exe -t 192.168.1.101

You can use Wndows PowerShell to create a logged continuous ping test. 

Ping.exe -t 192.168.1.101 | ForEach-Object {"{0} - {1}" -f (Get-Date),$_} | Tee-Object C:\Temp\ping-192-168-1-101.log -Append

The continuous ping will run until the PowerShell window is closed. The log output will look like this (intermediate log data has been cut out)

Trace route

Trace route or trace route with hop latency. The -Hops variable limits how many hops are shown.

Test-NetConnection 172.30.41.50 -traceRoute

or

Test-NetConnection 172.30.41.50 -traceRoute -Hops 10 | select-object TraceRoute | foreach-object {test-connection $_.TraceRoute -count 1}

Open TCP port test

You can do a simple one time test of a port using the following command, be sure to enable HTTPS in Tesira Device Maintenance's Network Settings if a "true" result is desired::

Test-NetConnection -Port 443 -ComputerName 192.168.1.101 -InformationLevel Detailed | Format-List *

You can run an extended test of an open port using this command set. This example runs for 720 minutes (12 hours) testing the port using TCP once a minute and logging success (true) or failure (false) with the date and time.

$timer = new-timespan -Minutes 720
$clock = [diagnostics.stopwatch]::StartNew()
while ($clock.elapsed -lt $timer){
$command=Test-NetConnection -Port 443 -ComputerName 192.168.1.101 -InformationLevel Quiet | ForEach-Object {"{0} - {1}" -f (Get-Date),$_} | Tee-Object C:\Temp\check-192-168-1-101-port-443.log -Append
cls
$command
start-sleep -seconds 60
}
write-host "Timer end"

The continuous port test will run until the timer expires or the PowerShell window is closed. The log output will look like this (intermediate log data has been cut out)

A test for multiple open TCP ports on one or more devices can be run using the script below. 

# Biamp Tesira port test
#
# Outputs a unique log file for each IP address saved in C:\Temp\PortTest-$Ipaddr.log
#   To save one file per port per device edit the 2 appearances of C:\Temp\PortTest-$Ipaddr.log to C:\Temp\PortTest-$Ipaddr-$Port.log
# Output reports results show in real-time in Powershell window
# If a device/port fails to respond it will delay the next test as Test-NetConnection retries the device
