HTTP phonoe operation

[Stewaro1]

I am about to do firmware updates for all phones in enterprise. Primarily have 9611g phones. There are some site with 46xx phones in contact center. My question evolves around how the phones interact with the http server to download firmware. My DHCP options fro tftp look like:
Option 176
TFTPSRVR=10.xxx.54.139,10.xxx.24.21,L2QVLAN=301,L2Q=1
Option 242
TFTPSRVR=10.xxx.54.139,10.xxx.24.21,L2QVLAN=302,L2Q=1
Since I am stopping and starting network regions from CM to effectively reboot the phones, My Question:
Are the phone coded to; How do the phones via for connection to tftp server? Will they load balance across both the servers? Do they wait for connection if they get busy from too many request to server?

Your DHCP options is missing the http server which is used by the 9611G. If unable to connect, the phones will wait and try again up to a certain time limit.

9611G use the option 242, and use HTTP not TFTP. So the 9611G do not have a file server option to pull the file from.

Or LLDP if you got avaya switches! Just wish it wasn't so IPOffice centric and only supports httpsrvr and not httpdir
