use alternate TFTP server for phone firmware

Unanswered Question
Jul 23rd, 2009

Hi all,

Can I use an alternate TFTP server for specific phone firmwares?

I want to do something like that:

phones 7970 will take firmware files from router with theese commands:

tftp-server flash:/SCCP75.8-4-2S.loads

tftp-server flash:/term70.default.loads

tftp-server flash:/jar70sccp.8-4-1-23.sbn

tftp-server flash:/dsp70.8-4-1-23.sbn

tftp-server flash:/cvm70sccp.8-4-1-23.sbn

tftp-server flash:/cnu70.8-4-1-23.sbn

tftp-server flash:/apps70.8-4-1-23.sbn

But I want that for example 7911 phones take their firmware files from an external TFTP server (PC). But I don't know how to do that. How I can specified external TFTP for that files?

Thank in advance.

I have this problem too.

If you have configured a dhcp pool on the router you can specify a different tftp server with option 150.

See this example:

ip dhcp pool PHONE

network 192.168.1.0 255.255.255.0

option 150 ip 10.1.10.250

default-router 192.168.1.1

Thanks for your answer Giordano, but in that case all files must be in the alternate TFTP. I want to have some files in the router TFTP, and other files in an alternate TFTP.

With new IOS version you can have different tftp options:

DS(config)#tftp-server ?

archive: Allow URL file TFTP load requests

flash: Allow URL file TFTP load requests

null: Allow URL file TFTP load requests

nvram: Allow URL file TFTP load requests

system: Allow URL file TFTP load requests

tmpsys: Allow URL file TFTP load requests

yes giordano, this is the way I'm looking for but I don't Know how to use that, and I cannot find any documentation about that.

I usually use falsh: option but what's the option for an external TFTP server?

archive: ??

flash: NO

null:

nvram: NO

system: NO

tmpsys:
