CUCM 11 Demo Setup NTP failed

[BALAMURUGAN SINGARAM]

For a demo CUCM 11 we are installing on Cisco UCS C220M3 server.

The ESXi is in subnet 10.10.10.0/24

The Voice subnet 10.10.11.0/24

The NTP server 10.10.12.0/24

From ESXi host we are able to reach all the above subnet default gateway but during CUCM installation at network configuration it failed to reach Voice default gateway and NTP.

In ESXi added Voice vlan ID - 300 and applied the voice vlan in CUCM HOST, but NTP and default gateway readability problem we have. Please advice.

There is nothing to advice really, this is related to Network Connectivity only check with your Internal Network Team and look for any firewall etc along with reviewing the settings for Virtual Machine again.

There is no firewall all the lab setup connected to single switch, IProuting is enable with SVI interface. From ESXi able to reach all the default gateway.

But during CUCM installation it gives error to reach network defualt gateway and NTP.

3570 Switch can act as NTP server ? we configured a loopback IP as ntp master with ntp stratum 0

ESXi -> Networking -> Click on VM Network and click on edit -> in General tab do you have selected VLAN ID(optional) ?

And, connect a laptop directly to UCS server and use laptop ip address as a default gateway and check whether Laptop is reachable from inside OR you can Install a windows machine on same UCS server and do the same again.
