Switch problem when configuration finish
Dear All Friend,
Now, we have more than 10 switch with various product from HP/3Com (Baseline 2928 SFP, 2952SFP, 3Com superstack/4400/4200), each switch connecting each other via fiber.
All switch still default (use: vlan default: ID 1) and each connected with vlan type access.
All switch with STP on by default.
There was something make me curiosity/strange, if i finish editing configuration to the switch, switch reboot, but from my desk i see all switch reboot too (check via ping) about 2-3 second.
I don't understand with the switch why if i only change/edit configuration to 1 switch can take effect to other switch too (reboot).
Is there any experience with the problem that i have?
Thank you for your time/reply, i appreciate that.
Thanks
P.S. This thread has been moevd from Switches, Hubs, Modems (Legacy ITRC forum) to Comware-Based. - Hp Forum Moderator

Re: Switch problem when configuration finish
Full mesh connectivity is somewhat strange topology. Do U have HP switch meshing feature utilized? Do U have Single IP management configured?

Re: Switch problem when configuration finish
If your ping failed for 2-3 seconds, that is nowhere near the time it takes for a reboot.

Re: Switch problem when configuration finish
Did you check on the uptime on the switchs to see if the really reboot?
2-3 sec with no ping is more likely to be a spanning-tree calculation.

Re: Switch problem when configuration finish
Hi gushim
You need to clarify a few things:
You say : "we have more than 10 switch ... each switch connecting each other via fiber."
That - when read literally - sounds like you have a full mesh. (or 10 switches, that would be 90 connections.) I don't think thats what you have, so could you describe the topology.
You say: that when you reboot one switch, the other switches reboot. How do you know that they reboot? ( you cannot really check that via ping.)
My best guess is that you loose the connection to the switches, because you trigger a recalculation of the spanning tree. This might explain the 2-3 seconds you talk about.
Regards.

Re: Switch problem when configuration finish
Dear All my friends,
Thank you for your time to reply my post. I attach my network diagram, and i can explain all switch still use default vlan 1, and STP enable. I read on this post there will take 2-3 second for STP to recalculation of STP. If like that is it normal? or i can reconfigure the STP so if i save the configuration the STP no need recalculation again.
Thank you so much for your time and reply
Gushim

Re: Switch problem when configuration finish
You appear to not have any loops in your topology - so your STP should remain stable.
Have you reduced your STP priority on your 5500 to 0, or 4K?

Re: Switch problem when configuration finish
Hi gushim,
its a simple topology.
But you need to be more precise. Because - I can easily explain what you experience, when i look at your diagram.
If you sit at your laptop, and reboot say switch 4:
- You'd loose connection to all switches but 7 and 9.
- Because of spanning tree TCNs you'll have several links going trough leaning and listening phases.
Regards.
