How To Change The IP Address On Cisco Unified Communications Manager (Call Manager)


Hello, everyone, it says: Jason will for geeks eights and today I’m gon na be showing you how to change the IP address of your C UCM cluster. Now the goal is to move from one network to another network, now keep in mind that in doing so, if you’re in a live production network, this will terminate your the license. You have associated to your caesium, but you can just contact Cisco and they’ll. Give you a new license, so you can Rijo store IP address that you want. So it’s not a big deal, but you do have to get involved with Cisco to do that if you’re doing it in a production network.

Now, if you’re doing it for layout purposes, it doesn’t really matter if you mess with the license, because you’re not paying for a new license and you’re just running on the demo license anyway. All that being said, let’s get started, so our current situation is we’re on the 192.168 15.0 network and our goal is to go to the 100 168 1.0 network.

So the way that’s done and before I get started when you’re messing with these vm’s, you may mess up here and there something may go terribly wrong. It’Ll be a great idea for you to actually go to the to the virtual machines that you’re about to attempt to change the IP addresses on and create a snapshot. That way. If you mess something up, you can always revert back to the snapshot and be able to start afresh and in fairly a pretty quick time versus messing up completely having a delete of VM image and start all over again. So it’d be a great idea for you to start right now and create a snapshot of all of the images that you’re about to mess around with.

What I like to do is use a virtual server to actually browse to the publisher to make the changes on the IP addresses initially. So I’m gon na log in to my where I actually I’m gon na, go over to my Windows: 2008 server that it’s only 1 or 2 168 15.0 Network and login to the publisher. Now it’s all about doing things in a proper order. The first thing that I need to do is go to system server, click on fine change, the subscribers IP address, changing it to 1
11 1.

1 hit save alright. Next, I’m gon na go over to the subscribers command line interface and since I’m actually gon na need to change the default gateway. I’M gon na go ahead and do that first before I change the IP address and we do that by doing the set Network gateway command and there’s finders, it says it will cause the network, the temporary loose connection we’re gon na hit. Yes, on that, now we’re going to actually change the IP address of the subscriber and we do need to put the subnet mask, and this is basically on the say by changing IP addresses, you’re going to lose the license that is associated to the IP address, which Is fine if you’re in the production network, you need to go ahead and immediately call Cisco, tell them that you’re making a change to the network and you’re gon na need the new license for the IP address that you were about to assign and it’s free of Charge it’ll just be a time process and as soon as you make the changes to the IP address, it will immediately restart the servers by the subscribers restarting. Are we gon na go ahead and go back over to our windows in 2008 server and change the IP address from the web, app main page for the publisher, so we’re gon na go back and we’re gon na go to our publisher change it to 110.

Save now this next step, we do need to wait for the subscriber to completely come back up, so we’ll sit around and wait for it. Okay, the subscriber is starting to come up now and in a second, you will see the new IP address of 192. 168. 1.11, there it is now.

What I need to do next is tell the subscriber to stop looking for the publisher at 192, 168, 15.10 and instead look for it at 192, 168 1.10, and we do that by doing the set publisher command so that command is set Network lustre, publisher, IP 192
168.1.1, now we’re going to go over to the publishers, command-line interface and because we’re going to a new network that has a new default gateway.

We need to initiate the set gateway command on the publisher as well. Yes, next, we need to sit the network IP address, and in doing this, it will immediately restart the publisher. Okay, now that the publisher is coming back up, you will notice that the IP address has changed to a 192 168 1.10 there. It is we’re gon na give you just a little more time before the publisher completely stands up, so you’ll notice.

If we browse over to the Windows 2008 server, that’s on the 192 168 15.0 network. You see that the publisher has timed out. It is no longer available to that network. So, let’s go over to the 192 168 1
0 Network and see if everything is up and running on that side – and this is my publisher IP address – then we change it to logged in okay.

We log it in just fine. Now we’re just going to do a simple replication test just by creating something in the publisher and then we’re going to jump over to the subscriber to see if it replicated to the subscriber. So I’m gon na create a partition and if I hit find you see, there’s no partitions here. So I’m gon na create one called test. Okay, so now we’re going to try to log into the subscriber and we need to see if the test partition got created over here, and it did indeed guys.

So that means we successfully change the IP addresses of both of our publisher and subscriber and did a replication test, and that was successful. So that completes this tutorial.
