I phrased that wrong,

I phrased that wrong, regardless of how many TFTPs you might be able to deliver, phones will only take a primary, and alternate TFTP. They will disregard any other TFTPs listed.

Hi Clark, for your first

Hi Clark,

 

for your first query, if you have Pub and Sub -1 as tftp mentioned in DHCP pool, then, there is no need to change for SUB-2 since phones have SUB-1 as tftp available till the PUB is Online.

 

for second query, u can go for this option since the servers are part of same CUCM cluster.

DHCP only delivers 2 TFTPs,

DHCP only delivers 2 TFTPs, that's all the redundancy you get.

Dear Jaime, So you mean to

Dear Jaime,

 

So you mean to say that all DHCP servers (windows, infoblox,etc,etc )  we deliver only 2 no's of TFTP,

thanks

Thanks for the reply and it

Thanks for the reply and it is nice to have a expert reply.

so what i understand from your reply is that if publisher fails change the TFTP options in DHCP to sub-1 and sub-2 , till the publisher hardware is replaced with the new.

question:

suppose If i have a distributed call processing with sub-2 in DR than the user sitting in DR will have a DR Subscriber as listed in DHCP for 1st TFTP and the alternate TFTP will be HO publisher or subscriber

Please correct

Thanks
