2.
Special Upgrade Information
The following sections include information that you must know before you begin the upgrade process.
•
Write-Cache
A disabled write-cache on the server causes the upgrade process to run more slowly. Multiple factors, including dead batteries on older servers, can cause the write-cache to get disabled.
If you determine that your write-cache is disabled because of a dead battery, you need to replace the hard disk controller cache battery. Follow your local support procedures to get this battery replaced.
To determine the status of the write-cache, from the CLI, execute the show hardware command.
Making Configuration Changes During an Upgrade
The administrator must not make any configuration changes to Cisco Intercompany Media Engine during an upgrade. Configuration changes include any changes that you make by using the command line interface (CLI).
Ordering the Upgrade Media
To upgrade to Cisco IME Release 8.0(2), use the Product Upgrade Tool (PUT) to obtain a media kit and license or to purchase the upgrade from Cisco Sales.
To use the PUT, you must enter your Cisco contract number (Smartnet, SASU or ESW) and request the DVD/DVD set. If you do not have a contract for Cisco Unified Communications Manager, you must purchase the upgrade from Cisco Sales.

CSCti60604 Several syntax and command changes needed in IME ASA setup guide
The following procedures have been corrected for Caveat CSCti60604:
Configuring NAT for Cisco Intercompany Media Engine Proxy
To configure auto NAT rules for the Cisco UCM server, complete the following steps:
Step 1
Example: hostname(config)# object network ucm_real_1Step 2
Example: hostname(config-network-object)# host 192.168.10.30Step 3
Example: hostname(config-network-object)# description "Cisco UCM #1 Real IP Address"Step 4
Example: object ucm_real_2 will contain host 192.160.10.31Step 5
Example: hostname(config) # object network ucm_map_1Step 6
Example: hostname(config-network-object) # host 209.165.200.227Step 7
Example: hostname(config-network-object)# description "Cisco UCM Translated IP Address"Step 8
Example: object ucm_map_2 will contain host 209.165.200.228Step 9
Example:hostname(config)# object network ucm_real_1hostname(config-network-object)# nat (inside,outside) static ucm_map_1hostname(config-network-object)# exithostname(config)# object network ucm_real_2hostname(config-network-object)# nat (inside,outside) static ucm_map_2(Optional) Configuring TLS within the Local Enterprise
The trustpoint needs to be enrolled before an identity certificate can be exported. The following step was added after step 2 of the procedure(Optional) Configuring TLS within the Local Enterprise:
Enroll the trustpoint before exporting the identity certificate. (config mode) crypto ca enroll <trustpoint>
The trustpoint in this case is local-asa.
Enabling SIP Inspection for the Cisco Intercompany Media Engine Proxy
In Step 9 and 12 of the procedure Enabling SIP Inspection for the Cisco Intercompany Media Engine Proxy, the "inspect" syntax is incorrect. The correct syntax is:
inspect sip [sip_map] uc-ime <uc_ime_map> tls-proxy <proxy_name>
Validation Parameters
The Cisco IME server relies on validation parameters to establish the security (number of calls required to learn a route) for call validation. By default, the system uses "medium security" values, and these values are designed to provide a sufficient level of security for most Cisco IME deployments. These "medium security" values will require multiple calls to numbers enrolled at a remote Cisco IME Server before any routes can be learned to CUCM's attached to that Cisco IME Server. It may take 2 hours or more before a route is learned even if there is a sufficient call volume to numbers enrolled at a remote Cisco IME Server. During system installation and configuration, you may wish to see a validation happen quickly. This can be done by lowering the validation parameter settings. It is very important to note: if you set these parameters low for testing, be sure to set them back to their default settings as soon as installation/testing is complete. This will insure good security for normal system operation.
To return the validation parameters to the default values, execute the following CLI commands:

Customer Alerts for Software Configuration and Message of the Day
Because the Cisco IME server is part of a larger distributed cache ring (DHT ) network, Cisco IME Network Administrators will need to inform customers of new software releases and maintenence in the network.
Message Of The Day
Message of the day alerts are informational
To view the entire message, execute the show ime motd CLI command . The current message of the day displays (if one exists).
Because these are informational messages, in most cases, no action is required.
Example
admin:show ime motd==============================================================Message Id = Fri Apr 2 08:36:10 2010Message = Cisco is performing upgrades on bootstrap servers today, DHT health may go to Yellow or Red. This situation should not last more than one hour.Repeat = 60 minutesSeverity = errorSWUpdateRequired
The SWUpdateRequired alert displays when your server is running a version of software that can be upgraded to a newer version.
Depending on the urgency, this alert may be informational, or critical (if there is an urgent need for your version to be to updated right away).
In some critical cases, if you do not upgrade the server within the given timeframe, the server may be unable to connect to the network.
To show all software configuration messages that have been sent, execute the show ime software-config version all CLI command
You will only see the alert if your server is running one of the versions listed in the "From" column.
Example
admin:show ime software-config version all===============================================================From Version To Version Criticality Note===============================================================8.0.2.10000-8 8.0.2.10000-13 recommended Please upgrade to 9009 in next 48 hrs===============================================================Set the VAP Interface Between the Cisco IME Servers and the Associated Cisco Unified CMs to Encrypted
Cisco recommends that you set the VAP interface between the Cisco IME servers and the associated Cisco Unfied CMs to encrypted.
Check to see if the authentication mode for all vapservers is already set to "Encrypted" by executing the show ime vapserver all command from the Cisco IME server CLI.
If they are not set to encrypted, refer to the Cisco Intercompany Media Engine Installation and Configuration Guide for instructions.
Note
NTP Server Configuration
The Cisco IME server requires a properly functioning NTP server configuration.
To verify NTP operation, execute the utils ntp status CLI command and insure that the Cisco IME server is connected to the appropriate NTP server and that the UTC and local times are correct.
Customer Information
The Cisco IME server stores contact information for your location which allows Cisco IME administration to contact you if the server is not configured properly (if, for example, it rejects connections from other servers).
To display the customer information settings, execute the show ime customerinfo command.
To change or add to the customer information settings, exectue the set ime customerinfo command. You will be prompted for contact information.
Transformation patterns
Transformation patterns should always be in non-null partitions that are not used for routing.

Tip
Understanding the Fixed-in Version Field in the Online Defect Record
When you open the online record for a defect, you will see data in the "First Fixed-in Version" field. The information that displays in this field identifies the list of Cisco Intercompany Media Engine interim versions in which the defect was fixed. These interim versions then get integrated into Cisco Intercompany Media Engine releases.
Some more clearly defined versions include identification for Engineering Specials (ES) or Service Releases (SR); for example 03.3(04)ES29 and 04.0(02a)SR1. However, the version information that displays for the Cisco Intercompany Media Engine maintenance releases may not be as clearly identified.
The following example shows how you can decode the maintenance release interim version information. These examples show you the format of the interim version along with the corresponding Cisco Intercompany Media Engine release that includes that interim version. You can use this examples as guidance to better understand the presentation of information in these fields.
