Installing CUCM 8.5 ON VMware Workstation.

Posted: Thursday, April 4, 2013 by Mahmoud Ramadan Ali in Labels:

Installing CUCM on VMware is a straightforward process,only two issues will face you during the installation:

1.The Configuration Of The CUCM NTP Server.
CUCM need NTP  server to synchronize it's time with, you can use external NTP pool or configure your router as internal NTP server -the option we use- to syn with.

2.Upgrading the VMware tools.
The installtion is successful,but you can't get the CUCM administration web page?! this is because you need to upgrade the VMware tools on CUCM to fix any network connectivity issues.

Note:The CUCM VM settings in VMware like this:

Note:In GNS3 i'm using C2691 as NTP server and it's directly connected to the CUCM VM on VMnet1 host only virtual adapter,also the gateway IP address configured on the VMnet1 NIC must be the same gateway IP address configured on the CUCM NIC.

1.Configuring The NTP Server:

Enter configuration commands, one per line.  End with CNTL/Z.
HOT.CISCO.LABS(config)#interface FastEthernet0/0
HOT.CISCO.LABS(config-if)# ip address
HOT.CISCO.LABS(config-if)#no shut
HOT.CISCO.LABS(config)#ntp master 4
HOT.CISCO.LABS(config)#do show ntp status
Clock is synchronized, stratum 4, reference is
nominal freq is 250.0000 Hz, actual freq is 250.0000 Hz, precision is 2**18
reference time is C0294593.3646AA33 (00:10:59.212 UTC Fri Mar 1 2002)
clock offset is 0.0000 msec, root delay is 0.00 msec
root dispersion is 0.02 msec, peer dispersion is 0.02 msec

2.Intsalling The Call Manager (CUCM):

Note:The GW IP Address will be the same as the  NTP server IP address.

3.Upgarding  The VM tools Via The Console.

1.From the VMware console enter the command "utils vmtools status" this will tell you the current version.
2.Go to the VMware menu and select VM - Update VM Tools,from the VMware console enter the command "utils vmtools upgrade" Enter "y" and the system will restart after the upgrade.After you are back up run the command "utils vmtools status" to verify the upgrade.The only odd thing that I experienced is after you enter "utils vmtools upgrade" and you enter "y" for yes nothing happens.I needed to press "y" and enter a number of times before the upgrade started.

4.Getting The CUCM Web Administration Page.

Now,you are completely ready to connect to the CUCM administration page,open your browser and connect to

Note:I can't finish this before telling you about the most important usable commands to troubleshoot any issues:
1."utils ntp status" will show the NTP synchronization status with the NTP server.
2."utils network ping <ip>" to ping any IPaddress.
3."show network eth0" to get INFO about the status of the CUCM NIC.
4."set network status eth0 down" and "set network status eth0 up" to change the status of the CUCM NIC up and down.
