CUCM Upgrading Device Load (Phone Firmware) on TFTP Nodes Only

[L.K.]

Symptoms

CUCM Cluster with either:

• Dedicated TFTP nodes (TFTP1 & TFTP2, Primary & Secondary)
• Only certain nodes within cluster running TFTP services.

Requirements to upgrade specific device phone models with new firmware load version.

Diagnosis

Limit loading additional files onto cluster nodes unnecessarily.

Limit increasing DRS backup size.

Improve load management moving forward.

Solution

STEP	ACTION	NOTES / OUPUT
1	Upload desired COP install file to SFTP
2	Complete your desired cluster/node pre-checks
3	Note MD5 hash of new firmware COP file

13	Compare and verify CUCM calculated MD5 hash matches
14	Enter yes to start the firmware install	The install begins, scrolling the log/output on CLI
15	Installed completed	CLI output Successfully installed cmterm-88xx-sip.12-7-1-0006-413.k3.cop.sgn Locale cmterm-88xx-sip.12-7-1-0006-413.k3.cop has been installed successfully.   A reboot is not necessary for the changes to take effect.
16	Run show version active	Verify desired firmware install file is present in output list

23	Restart Cisco Tftp service on TFTP1 & TFTP2	Verify the service is showing as started
24	Restart Cisco Tftp service on any additional TFTP nodes in cluster	Verify the service is showing as started
25	Apply Config to the pertaining devices to push and upgrade phones to new firmware version	This can be completed via BAT (Phone --> Update Phones --> Query)
26	Monitor and allow time for phones to download/upgrade firmware
27	For all TFTP nodes return to CLI and run show status
28	For all TFTP nodes return to CLI and run show version active	Verify desired firmware install file is present in output list
29	For all TFTP nodes return to CLI and run utils service list	Verify services are running as previously, including "Cisco Tftp"
