Is it correct that the cli command "

Code: Select all

reload cold

" is actually a warm reboot of the switch ?

If yes, could you please add a cold reboot command/function and change existing to "

Code: Select all

reload warm

Yea, I agree it should be called reload warm

A cold reboot is not possible with the AC models as a cold reboot is a power cycle and there is no way to do that with the AC models.

We could make the SMART DC switch cold reboot as we could tell the power supply to cut power for 5 seconds to the switch board but no way to tell the AC power supplies to cut power.

Is it something that can be added to new AC switch models in future ?

PS: Please change command from reload cold to reload warm....

Code: Select all

switch01# reload
cold Reload cold.
 defaults Reload defaults (will reboot the switch).

So to reboot switch I should chose "reload defaults" which in my understanding would be reboot and factory default ?
And cold reboot sounds like factory defaults ?
Still very confusing description, and nothing has changed in later firmware versions ?

Actually we are mimicking Cisco and industry standards

In a Cisco you have
reload cold ,= reloads the OS and services basically starts over and then the configuration this takes longer
reload warm = fastest way to reload router where it simply clears the config from memory and reloads the config but does not restart or reload the OS or services

Now this is a little bit different in the switches boot log which will indicate warm boot and cold boot
warm boot means that the OS restarted reloading the OS and config
cold boot means the switch detected that the power was cycled so all the chips on the board were completely depowered and the hardware started cold

again even though this differs from from the cold warm on reload verses boot again this is industry standard. We put the boot warm or cold in the boot log when we were debugging an issues way back in v1.X.

If you follow the firmware history when we first started selling the switches we touted that you could upgrade the firmware and you only dropped 1 ping but later found this caused other issues so we made a firmware upgrade complete reload of the OS which means you could loses many more mings and even more pings if the switch is in say an OSPF routed network as the OSPF adjacency would now see the drop and you also have to wait for OSPF to do a converge after traffic started flowing again.

There is no way in software to actually do what the industry calls a COLD RESTART where the board is depowerd as this would require a lot of additional hardware that I have never seen in any device that is in my price range but I do exist in telecom equipment and aerospace equipment but they cost way more money and sometimes we all have to POWER CYCLE a device a normal software reboot does not work and that would be hard to do say on a satellite or even a cell tower from their central offices that are hundreds or thousands of miles away and they have much larger budgets so yea its there. But then again this is why there is a market for poweer stips that allow remote power cycles for the little guys like us.
