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 | |
4 | Access CLI, console or SSH, of TFTP1 node (Primary) | |
5 | Runshow status | CLI outputs current node status and basic details |
6 | Runshow version active | CLI outputs current version and installed files |
7 | Runutils service list | CLI outputs current running services |

12 | Enter corresponding number option to desired firmware file | CLI outputAccessing the file. Please wait... |
13 | Compare and verify CUCM calculated MD5 hash matches | |
14 | Enteryesto start the firmware install | The install begins, scrolling the log/output on CLI |
15 | Installed completed | CLI outputSuccessfully installed cmterm-88xx-sip.12-7-1-0006-413.k3.cop.sgn |
16 | Runshow version active | Verify desired firmware install file is present in output list |
17 | Runutils service list | Verify "Cisco Tftp" is continuing running on node |
18 | Repeat steps 4-17 for TFTP2 (Secondary) | |
19 | Repeat steps 4-17 for any additional TFTP nodes in cluster | |
20 | Access CUCM Web GUI | |
21 | Navigate to Device --> Device Settings --> Device Defaults | |
22 | Update the "Load Information" for the pertaining Device Types (models) with newly installed firmware version and Save | |
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 runshow status | |
28 | For all TFTP nodes return to CLI and runshow version active | Verify desired firmware install file is present in output list |
29 | For all TFTP nodes return to CLI and runutils service list | Verify services are running as previously, including "Cisco Tftp" |
30 | For all TFTP nodes return to CLI and runshow tech devdefaults | Verify new updated device default firmware loads listed for pertaining models |
31 | Exit CLI |
