NIC config of VMware installation of Call Manager

System version: 8.6.2.22900-9
VMware Installation: 1 vCPU Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz, disk 1: 80Gbytes, 4096Mbytes RAM
A few month ago we had a vendor come in and upgrade our old VOIP system with a VMware solution of Call Manager. Versions are shown above.
I use Veeam to backup these VM's and it was taking hours to finsih so I starting digging into VCenter to look at the netwroking setup.
Even though the server has gigabit ethernet cards they "hard coded" the speed down to 100 Meg and changed the duplex to half.
Does anyone know of any reason why they might have done that? Will it fail if I change the speed to GB and utilze full duplex?
thanks...

Questions and a comments
Questions in the post above you mention...
"At this point, I would probably try the Hypervisor and Switchport hardcoded at 1000/Full to match CUCM. Check interface counters and watch for errors and runts."
When you refer to "Switchport" I am assuming you are you talking about the physical port on our physical switch?
which is interesting becasue I just looked only to discover that on our physical cisco switch (Catalyst 4506) that our phone system is physcally plugged into our 10/100 module and not into our gig module. So even if I made all of those changes I still would have been at a 100 MPs speed becasue of the physical connection to our switch. So obviously... I would need to change ports on the physical switch to the gig module, correct?
question 2...
monitoring the ports for errors and runts, again I am assuming you are talking about the physical Cat 4506 switch?
Assuming then I move the connections into gig ports 5/26 & 5/28, etc...
From a telnet session into physical switch... after enable mode type...
switch#show int gigeth5/26
and I will see stats from that interface correct? or do you look for these in a different mannor?
comments... first of all, thank you....
second....
I am not sure I quite understand anything about you very last post.... about the restricted UC and Cisco support..
yes, I am running USC C220 M3 servers... are you saying that if I have over 1000 users that TAC will not support performance issue? I ask becasue we only have about 125 users....

IPCC and CVP in VMWare, same as Call Manager

Hi All;
As I know that new version of Cisco Call Manager (version 8) is working based on VMWare (and it is must), so I am asking if there is a versions for IPCC and CVP working on VMWare (this for production and not for LAB).
Appreciate kindly help and support.

UCCE 8 on VMware 4.0 on the Cisco UCS hardware only.
But in a lab environment, many (most) of us are using VMware in some shape or form.
I have 5 x HP DL380G5 2 CPU servers each with 6GB in a rack running ESX 3.5, with a smaller server for the Virtual Center software. Each ESX host can support 7 virtual machines - DC, Rogger, AW/HDS, PG, CVP7, CUCM and CUPS. You do need a lot of disc space though - especially CUPS (80GB) and CUCM (40GB). And you need a lot of extra space for snapshots.

Cisco Call Manager TFTP requests.

I was looking to see if there was a way to look at what devices request config files from a Cisco Call Manager TFTP server.
I know that you can use RTMT to look at the total number of requests made, but is there a way to know what device make the request.
Thanks in advance,
Robert

You could do this by doing a packet capture on the server as described in the link below

Call manager and rme config archive report

Hi,
I know that rme does not support the call manager for config archive. It is clear.
The RME home page show config archive status for failed devices and there are some devices which are not supported by RME config archive.
I've set this devices to suspended state in RME but config archiv is trying with this devices also.
This is a financial costumer and the local Financial supervisory authority would like to see all devices config is saving successfully.
How can i exclude the call manager and similar devices from config archiv process and status reports?
Regards,

Hi,
I would like to qoute from RME help.
Working With Suspended Devices
Suspended device state cannot participate in any RME application flows but all historical data pertaining to the device will continue to be maintained by RME.
Nevertheless the RME is trying to fetch the config from suspended devices!!!
What is the truth in this thing?

Call manager installation

i need to know how to install call manager on non cisco recomnerded hardware

Hi,
I can only re-iterate what Brandon has said and in no way use non-Cisco approved hardware for any live system. You will not get support and you are risking your business in doing so.
If this is for your own use, for learning purposes only, then it can be done, but be prepared to spend some time in doing it.
Follow the link already given.
You will need to install Windows 2000 server, then run the registry edits, then install SQL 2000. You will also need to install a 'Cisco' version of the OS; (2000.4.7 or similar).Then install the Call Manager software. Your machine needs to have a decent sized hard disk and at least 512M of memory just to run the software.
If you are learning, then I would also recommend 2 good books from Cisco Press
Call Manager Best Practices &
Troubleshooting Call Manager
As you won't get any support from Cisco!
You have been warned !!

Your help will be appreciated

Hi Syed.
Did you use an OVA Template to deploy your CUCM?
Please have a look to the following doc.

Call Manager Migration 7.1.5 to 9.1 / Trunking : ICT vs. SIP

Hello All,
Currently studying for CCNA Voice and have been asked by my current employer to upgrade CUCM 7.1.5 to 9.1.1. There has been a time frame put on the deployment however I want to dig pretty deep into the deployment to learn as much as possible. I am going to start by configuring a trunk between the 2 call manager clusters. from there I will add users to the new call manager and try to convert slowly to the new call manager instead of one big cutover. I will place a route pattern over the trunk so that cucm 9.1 will route through cucm 7.1 while I slowly convert users to the new system. I will then deploy directory numbers in a Staging partition that is not associated with any CSS. Once I have all users and phones configured on the new 9.1 call manager I want to use the bulk admin tool to change the staging partition to the working internal_PT production partition. The users will be imported from LDAP. My questions are, does this sound like a feasible plan? Is there any other difference between a SIP trunk and ICT besides the SIP and H.323 protocol? ( I prefer SIP from what I have read) and will having the same users on both boxes interfere with call processing, if these users and phones are not active yet?

Just for the record. I found the solution to my problem. Checking more logs I read this:
The installation has encountered a unrecoverable internal error. For further assistance report the following information to your support provider.
"/usr/local/cm/script/cm-dbl-ontape_backup-install RU PostInstall 9.1.2.11900-12 7.1.5.30000-1 /usr/local/cm/ /common/component/database /common/log/install/capture.txt " terminated. Exceeded max time (240)
The system will now halt.
So I accessed the Dissaster Recovery Section on CUCM and deleted the tape backup device that was configured there. After deleting it the upgrade went well.

Problem with Call Manager in VM ware

Hi All ,
Please help
I installed VM worksation in my laptop , and trying to install Call Manager inside it , My laptop connected to LAN with 10.26.152.27 with mask 224 , and gateway 10.26.152.1 . i am confuse what Network adapter i will use for VM ,and what TCP/IP range i configured to CUCM while installing to have it access from Web Browser

Arawat,
If in understand your question correclty, all you have to do is put them all on the same IP subnet, including the virtual network adapters that VMware will build on your laptop. Based on your Laptop IP 10.26.152.27, and your /27 mask you will probably want to give it an IP address between the range 10.26.152.2 to 10.26.152.30. Your gateway for all the virtual devices will be the same as the laptop, 10.26.152.1.

Multiple IPs in Call Manager

Hi,
We need to configure multiple IP addresses in a Call Manager version 8. Our customer has three diferent IP networks: One for management, one for signaling and one for media. Call Manager is connected to those networks using three NICs with different IP Addresses a should separate traffic.
Is it possible in CCM? I guess no, but is there any work around to get this functionality?
Thanks and best regards.
Raul

Not possible in CallManager, but you can achieve this with "VRF select" on IOS routers
