[cisco-voip] Issues with Peer Firmware Update, anyone?

Thu Jul 15 19:19:49 EDT 2010

Sorry I mixed this with another feature…but I found why I have negative feedback about it and decided before not to use it as much as I can:

https://supportforums.cisco.com/message/3062951 

but as per Cisco document below they says that it is the best choice for firmware upgrade…I just remember a limitation of the number of phones that can connect to a root phone at a time and that was a silly limitation but I cannot find any document right not that talks about this number; I remember that the subnet needed to be very small in order to have all phones upgrade using PFS

See Cisco link

have you tested it with a large number of phones in the same subnet?

What kind of problems?? Please be specific, I just googled "cisco telephone peer firmware update problems" and did not see anything of note. 

I am planning on implementing this on my 7.1.5 cluster to hopefully speed up firmware updates. I tested this option in our lab using a test bed of 15 telephones and it resulted in a significant reduction in bandwidth utilized and time required to upgrade and down grade 7962 telephones. I experienced no issues in my testing.

Google it you will find a lot of people facing problems with it…if the number of phones is not a big issue let it upgrade one by one from CUCM…otherwise go for peer method as it may have been enhanced in new codes.

Hi, guys! 

  Did anyone have any bad experiences using the Peer Firmware Update feature? I am planning to upgrade a 6.1(3) cluster to 6.1(5)
