Configure and Integrate CMS Single Combined

Introduction

This document describes how to configure and integrate Cisco Meeting Server (CMS) Single Combined.

the services to configure are Call Bridge, Webadmin, Web Bridge, Extensible Messaging and Presence Protocol (XMPP) and Lightweight Directory Access Protocol (LDAP) integration

Prerequisites

Requirements

Cisco recomends that you have knowledge of these topics:

Cisco Unified Communications Manager (CUCM)
Active Directory (AD)
Certificate Authority (CA)
Secure File Transfer Protocol (SFTP) client
Domain Name Service (DNS) server

Components Used

The information in this document is based on these software and hardware versions:

CMS version 2.3.7
CUCM version 11.5.1
Google Chrome version 69.0.3497
WinSCP version 5.7.7
Windows Server 2012

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Configure

Step1. Access CMS

The first time you Log in into CMS, the Welcome is shown in the screen and prompts to Log in
The default credentials are:

User: admin

Password: admin

After the credentiales are entered, the server asks you for a new password

It is recommend that a new admin user is created, it is a good practice in case you lose the password for one account.
Enter the command: user add <username> admin
Enter a new password and confirm the new password

Step 2. Change the Hostname

This change is optional
Run the command hostname <name>
Reboot the server
Run the command reboot

Step 3. Configure network settings

In order to display the current settings run the command ipv4 a
Add ipv4 configuration
Run the command ipv4 <interface> add <ipaddress>/<subnetmask> <gateway>

Configure the time zone
Run the command timezone <timezoneName>
In order to see all the available timezones, Run the command timezone list
Add a Network Time Protocol (NTP) sever
Run the command ntp server add <ipaddress>

Add a DNS server
Run the command dns add forwardzone <domain> <dnsip>

Note: A specific domain can be configured for DNS lookup, however if any domain can be resolved by the DNS, then use a dot as the domain

Step 4. License the CMS

In order to configure the CMS services, it requires a license to be installed
In order to generate and install the license the Media Access Contol (MAC) address is required, since the licenses will be matched to it.
Run the command iface a
Copy the MAC address
Contact your Sales representative so a license can be generated.

Note: The process to generate the license is out of the scope of this document.

Once you have the license file, rename the file to cms.lic
Use WinSCP or another SFTP client in order to upload the file into the CMS server

Once the file is uploaded run the command license
Reboot the server
Run the command reboot

Step 5. Generate and install certificates

Generate a Certificate Signing Request (CSR) for callbridge, webadmin, webbridge and xmpp
Run the command pki csr <service> CN:<servicefqdn> for this purpose.

Note: In this example, a single certificate for each server is created, you can create one certificate for all the services. For more information about certificate creation, review the Certificate Creation Guide

Two files are generated after running the command: .csr file and a .key file. with thename of the service you assigned on previous steps.
Download the CSR files from the CMS server. Use WinSCP or other SFTP client for this purpose.

Sign the CSR with a Certificate Authority
Ensure to use a template that contains Web Client and Web Server Authentication
Upload the signed certificate to the CMS server
Ensure to upload the Root CA and any Intermediate certificate that had signed the certificates

In order to verify all the certificates are listed on CMS, run the command pki list

Step 6. DNS Records

Create the DNS Address (A) records for callbridge, xmpp, webadmin and webbridge
Ensure all records point to the CMS IP Address

Create a Service Record (SRV) for xmpp-client
The service record format is

Service	_xmpp-client
Protocol	_tcp
Port	5222
Target	Enter the XMPP FQDN, for example xmpp.anmiron.local

Step 7. Service Configuration

Configure the callbridge:

Enter the command callbridge listen <interface>
Enter the command callbridge certs <callbridge-key-file> <crt-file> [<cert-bundle>]
The key-file is the key created when the CSR is created
The cert-bundle is the bundle of the Root CA and any other intermediate certificate

Note: The Call Bridge listen interface must not be set on an interface that is configured to use Network Address Translation (NAT) to another IP address

Configure webadmin:

Run the command webadmin listen <interface> <port>
Run the command webadmin certs <key-file> <crt-file> [<cert-bundle>]

Note: If the webadmin and webbridge are configured in the same server, they must be configured on different interfaces or listen in different ports, the webbridge requires to listen in port 443. The webadmin is usually configured in port 445.

Configure XMPP:

Run the command xmpp listen <interface whitelist>
Run the command xmpp domain <domain name>
Run the command xmpp certs <key-file> <crt-file> [<crt-bundle>]

Note: The domain name must match the domain where the DNS records were created.

Configure webbridge:

Run the command webbridge listen <interface[:port] whitelist>
Run the command webbridge certs <key-file> <crt-file> [<crt-bundle>]
Run the command webbridge trust <crt-bundle>

Note: The trust crt-bundle is the callbridge certificate and must be added to the webbridge in order for the callbridge to trust the webbridge, this will enable the Join as a Guest feature.

Run the command callbridge restart
Run the command wbeadmin enable
Run the command xmpp enable
Run the command webbridge enable

Note: The server must return SUCCESS for all the services, if it returns FAILURE, review the previous steps and validate all the configuration is correct

To allow the Call Bridge to access the XMPP service securely, it is necessary to provide a component name for the Call Bridge to use to authenticate with the XMPP service.

Run the command xmpp callbridge add <component name>
The result shows a Secret, as shown in the image

Copy the Secret value
Acess to the CMS web Interface
Navigate to Configuration > General
Enter the information

Unique Call Bridge name	Enter the name of the created callbridge, for example callbridge
Domain	Enter the domain name, for example anmiron.local
Server address	Set the CMS IP address, for example localhost:5223
Shared secret	Enter the Secret created in the previous step, for example 6DwNANabpumut14pAb1

Select Submit

Create an Incoming Call Matching Rule for Incoming calls
Navigate to Configuration > Incoming calls
Enter the information

Domain	Enter the domain name of the CMS server, for example anmiron.local
Priority	Enter a value for the priority, for eaxmple 0

Step 8. Integrate LDAP

Open the CMS web interface
Navigate to Configuration > Active Directory
Enter the information

Address	The LDAP server IP address, for example 172.16.85.28
Port	This is 389 if you are using a non-secure connection and 636 if secure connection is required
Username	Enter an Administrator of LDAP server, for example anmiron\administrator
Password	Enter the password of the Administrator user
Base Distinguished name	This is a setting from Active directory, for example CN=Users, DC=anmiron, DC=local
Filter	This is a setting from Active directory, for example (memberof=CN=CMS, CN=Users, DC=anmiron, DC=local)
Display Name	How the user name is shown, for example $cn$
Username	The Log in ID for the user, for example [email protected]
Space Name	How the space is shown, for example $sAMAccountName$ Space
Space URI user part	The URI to be dialed, for example $sAMAccountName$.call
Space Call ID	The Call ID to be used from webbridge, for example $sAMAccountName$.space
