I am getting an error too I am using VMware workstation 7, Linux 4-32bit for CUCM 8.5.1,2048 Memory, 80 GB disk space, Core 2 duo , 2 processor
but for me its not installation error,
what I am doing is I am Skipping the base configuration and doing installation ,
then I am doing base configuration after installation,
it gives me error for network connectivity check,I am using Host-only for network connection
and if I ignore that and move ahead then I am getting error at NTP server configuration,
it always asks for external NTP server as ref, not like the other versions of CUCM that you say no for external NTP server and then specify the time it self on CUCM,
so does that mean I need to give External IP only for NTP server or there is some work around.
Rest is fine in my case, installation is done very smooth...
With 8.5.x and above on any Cisco products you now require a ntp source to complete the installation , you can config an NTP server on your router.
thanx for the information on NTP,
I am using VMware workstation and I don t have any other device with me at this moment and I have connectivity to internet using datacard can this be useful...
Hi, yes you can point your server to a public NTP source, but you may need to open port UDP 123 on your firewall. Here is a link to public NTP sources, http://support.ntp.org/bin/view/Servers/NTPPoolServers
I think you didn't get what I was trying to explain,
I am running VMware workstation on my Laptop, and I am connected Internet using high speed USB datacard,
so I am not actually using my laptops NIC card to connect to any device, and I am using Host-only connection type on VMware will that work or I need to change to some other type on my VMware,
I am not there in any office network or LAN....
is this is useful for you to understand my scenario...
You can bridge VMware NIC to USB datacard or any NIC; by default it is bridged to NIC on laptop during installation;
You can select Auto bridge or bridge to specific NIC like USB datacard; of course that USB datacard must be inserted during CUCM installation;
Hey thanks for the information will try and let you know....
I was not aware it should be there at time of installation,
I thought it should be there at the time of Network connectivity check and NTP server check...
well, you ar eright, it does not have to be during installation, but it must be there and must be bridge to vmware.
My installation halted and network connectivity check failed untill I switched Vmware NIC to one connected to the Internet;
Thank you very much,
let me try and come back with results...
hopefully this should do...
For such an installation a router in GNS comes very handy. It also allows you to do the installation with the desired settings. You would not need to adjust the settings to the outside IP-addresses for to complete the install.
I am not that good with GNS but if you can provide some document or reference, on how I can integrate GNS and VMware that will be too much helpful for beginner like me,
I have just started to use VMware and GNS dont have much hands-on on both of them...
so if you can help that will be great....
The little trick her is to use a "cloud" to leave the captive environment of GNS. Pull a router and a cloud onto the worksheet and configure the cloud to connect to your physical or a MS-Loopback interface if you have one installed.
Then configure the router with your desired IP-address which will be the default gateway for your UCM. Configure the NTP on the router like this:
ntp master 4
ntp peer 10.1.1.1 <- the IP of CM as client
ntp server 18.104.22.168 prefer <- you don't need this if there is no connection to the internet. This is to sync the router
now bridge the VM to the same interface as you have chosen in the GNS cloud. You should have IP connectivity now
Thanx for the information will try and get back to you , just wanted to know one last thing before I try something,
I haven't installed MS-Loopback, I am going to use Ethernet port of my Laptop I have got the connectivity of GNS and my laptop,
for VMware I am using Host-only will that do or I have to select any other option,
and I am not giving IP address to the interface "VMware Network Adapter VMnet1", physically
I am only giving IP address to CUCM 10.1.1.10/24, GW 10.1.1.1
and my laptop interface "Local Area Connection" 10.1.1.1/24,
but according to above connectivity I will change my laptop "Local Area Connection" to 10.1.1.30/24
and will give 10.1.1.1 to my router on GNS and will apply respective commands for NTP,
I am aware how to set router as NTP master,
I was not aware how to connect GNS to my Laptop but from your explanation, is more than enough.
I know I am asking too much here but I have tried so many times to do installation, becouse of that I dont want to miss on anything....
Thank you very much ,
Configuration worked I am able to install CUCM and CUCX
I will try that also, with GNS3, and let you know how it goes.
At moment i'm using meinberg NTP software, also utilising Oxford University NTP IP's that are in the public domain.
But three attempts at 3hrs each time to load CUCMv8.6 is getting boring, my install screen crashes very late during the installition, NTP comes up fine "accessible", but the GW maybe the problem.
So i will use GNS3 and a cisco 7200 with an ios, and get back to this forum.
