ELAN Connections 2

[technickelone]

I plan on swapping out the hub for a switch for all the ELAN stuff (Callpilot,signal server, PBX Core 0 -1). Will there be any type of service outage in that time period.

It should be quick and dirty.

what's on the elan? the cp will go belly up and if you have symposium, that would need a reboot MOST of the time

Yes, when you disconnect the ELAN connections your Call Pilot will lose connectivity to the switch. Make sure everything in the switch is ready to move, and then just move your patch cords quick. There will be a temporary loss of signal, but if it's not too long it will restore.

It should be fast since it will be mounted and ready.

How about the cores?

If the cores are PII they will swap

For some reason the elan hub has a core router connection to the network in port one. Now, from what I am being told is that elan is just talk among the nortel equipment and should not be have a connection to any network outside its own vlan.

I can ping the ip's on that hub 137.128.xx.xx from my desk and I am on a different subnet.

That means the PBX and everything plugged in is subjected to broadcast storms. It has its own vlan, so can I just simply unplug that cable?

Just because you can ping it, doesn't mean it can see broadcast storms. Routers can prevent that.

Plug your switch into a hub port and give it a minute to synch up. Then, quickly move one patch cord from the hub to the switch and give the system 30 seconds to stabilze. Then do the next cord. If you're quick, your systems will barely blink.

This was a breeze-thanks for the advise.

The LAN connection is the only question I have. Does your ELAN hub/switch have a connection to your corporate LAN? I unplugged it that night to see what would happen and it caused the OTM clients to not transmit changes. That tells me that OTM is not configured correctly, or is it.

Many people will put a router in between the ELAN and CLAN. This is simply for management.

OTM requires a connection to the ELAN, but this doesn't mean that you must have an ELAN card in the OTM Server.

Here is what it sounds like:
There is a routing interface on the CLAN built to the ELAN. The router will block all of the broadcast messages from the CLAN to the ELAN. You should plug in a laptop with Ethereal or another packet sniffer to the ELAN just to verify.

I'd say that everything is configured correctly. You should leave the cable from the ELAN switch to the CLAN.

Another question concerning TM 3.0.. We have the TM server set up with dual NIC cards so there for it has both an ELAN and CLAN connection.. However, the customer does not have the ELAN embedded into their CLAN(ELAN is on a seperate hub with no public network connection,etc).. We are in the process of loading TM 3.0 clients onto their PCs. The only reason they are using the clients is for billing. IF my thinking is right, the TM clients do NOT need to be able to talk to the ELAN subnet just for billing usage due to the actual billing is done on the TM server that DOES have both an ELAN and CLAN connection, so we should be able to run costing reports and such once the clients are installed, even without have the PBX ELAN routed throughout the customer's network, right?
