Hi

We have a 'extreme 450e 48p' switch installed in our organization along with other networking equipments. When power is restrored 'extreme 450e 48p' switch reboot successfully before other networking equipment thereby create some problems, which we don't know why.

So, for a solution we restart this particular switch again by turning power off and then on for this particular switch after successful restart of all other networking equipments.

As per my understanding 5 minute delay to start booting of 'extreme 450e 48p' switch can resolve the issue, if it's so, please let me know how to create a delay or auto reboot once again this switch.

Any other solutions are most welcome.


Regards,

Hello hmrpanchai

I am not sure I understand.  There is no reason waiting 5 minutes would change the issue unless the other switches are running STP and the network has stabilized to stop some loop.

Extreme does not have STP enabled by default.

If you can explain the network layout and what the issue is then that would help.


Thanks

I am new to networking, can you please explain what STP is and how it can affect working of other switches, and why our switch works well on 2nd manual restart.

STP = Spanning tree protocoll.
If you want to learn more about it - Google is your friend mate. :)
You can also read about it in EXOS concept guide.

Hello hmrpanchai

STP, as mentioned by aTomo, is Spanning Tree Protocol.  The key word is that it is a protocol that just like OSPF or BGP or PIM needs to be designed into the network as it is an active protocol to remove loops in the network.  Over the years STP has morphed to keep up with the changes in designs and products and thus has become very complicated to get right.

Some vendors have STP enabled by default, which I assume is to help customers with accidental loops in the network, the problem is that in most cases the network is never correctly set up and can become an issue.

Extreme does not enable STP by default nor any other active protocol because we feel it is something that must truly be designed into the network.

I hope that helps
