This is the current topology: - Webserver in dmz is connected to ovens which is accessible from internet to control them i.e temp, start/stop etc... Required : - New switch was needed to connect more ovens. - New controller would be connected for better controls.( not managed by me). -Keep the Ovens network as isolated as possible from production while web server still be accessible from the internet for remote mgmt. - Web server can me moved Hope this makes things clearer...

Thanks for replies.... The webserver has a public ip open for https from internet. Devices which will connect with the new switch will get ip addresses from that new switch and will get a gateway in the same private ip range. If i connect that new switch with existing switch in the network with runs all public subnets, what are my options to make the devices on the new switch communicate with the webserver? Devices do not need to go to internet. They just need to connect with webserver(locally) on some port to be managed.

brain freeze.... need help How can i setup a small network with private ip range within existing network which have public ip range.? That small network would be on separate switch and would be used to control industrial ovens remotely(over the internet) As of today web server is in our dmz which can be accessed from outside.

Hi, Any clue why all configuration under the interfaces e.g portchannel etc.. lost after i truned both the switches ON ( active switch switchover ) after some days. I turned them off before going to vacations (they are not in production yet ). Have done many reloads and tested active/standby switchovers previously without any issue.

Because i wanted to test mchasis etherchannel behaviour with Hp first before starting migration. I think i should use a standalone hp switch with basic configurations ...

Yes, the third one is cisco 9407 pair configured with stackwise virtual. The plan is to replace the old cisco 6509E. All HP access switch would be connected to the new core with multi chasis etherchannel. C6509E ---- HP(20+ switches) is the old network topology where core is handling inter vlan routing. I am conecting the new cisco 9407 pair with multi chasis etherchannel to one of the HP switches. like this: C6509E ---- HP ====== cisco 9407 stackwise virtual pair.

@paul driver Yes, Thats how it is already on the old cisco core and is working alright. Issue comes while establishing port channel from a Hp to the new cisco switch. spanning-tree priority 15 is on HP which sets it to highest priority and old cisco has priority set to 24577. The new cisco switch has default 32768.

There is an old cisco 6509E core switch running pvst acting as CST root to all HP access switches which are running default mst. I am running a test by configuring lacp with our future core a C9407R pair (stackwise virtual) to one of the HP access switches. I have tried to -configure pvst filter command at HP side -portfast trunk command at cisco side -changed STP mode to pvst -making etherchannel with ON mode -used ports on same chasis result is pretty much the same every time. Link comes up for a few sec and then is err-disabled.
