Allow And Configure Firmware Upgrades - Cisco 8800 Series Manual

Allow and Configure Firmware Upgrades

Allow and Configure Firmware Upgrades
Firmware updates can be allowed at specified intervals. Updated firmware is sent from a server to the phone
by using TFTP or HTTP. Security is less of an issue with a firmware upgrade, because firmware does not
contain personal information.
You can also configure the parameters in the phone configuration file with XML(cfg.xml) code.
Before you begin
Access the phone administration web page. See
Procedure
Step 1
Select Voice > Provisioning.
Step 2 In the Firmware Upgrade section, choose Yes from the Upgrade Enable parameter.
You can configure this parameter in the phone configuration XML file (cfg.xml) by entering a string in this
format:
<Upgrade_Enable ua="na">Yes</Upgrade_Enable>
Options: Yes and No
Default: Yes
Step 3 Set the Upgrade Error Retry Delay parameter in seconds.
The upgrade retry interval (in seconds) applied in case of upgrade failure. The device has a firmware upgrade
error timer that activates after a failed firmware upgrade attempt. The timer is initialized with the value in this
parameter. The next firmware upgrade attempt occurs when this timer counts down to zero.
You can configure this parameter in the phone configuration XML file (cfg.xml) by entering a string in this
format:
<Upgrade_Error_Retry_Delay ua="na">3600</Upgrade_Error_Retry_Delay>
Default: 3600
:
<tftp|http|https>://<ip address>/image/<load name>
Step 4
Set the Upgrade Rule parameter by entering a firmware upgrade script that defines upgrade conditions and
associated firmware URLs. It uses the same syntax as Profile Rule. Enter a script and use the following format
to enter the upgrade rule:
<tftp|http|https>://<ipaddress>/image/<load name>
For example:
tftp://192.168.1.5/image/sip88xx.11-0-0MPP-BN.loads
tftp://192.168.1.5/image/sip78xx.11-0-1MPP-BN.loads
You can configure this parameter in the phone configuration XML file (cfg.xml) by entering a string in this
format:
<Upgrade_Rule ua="na">http://10.74.10.205:6970/sip8845_65.0104-MPP-9875dev.loads
</Upgrade_Rule>
