static mapping, DHCP on a Cisco 2900

Hello,

 

I am planning to do static mapping, DHCP, on a Cisco 2900.  So I have a file with static bindings and I saw that that file is 'referred' to with something like:

Router(dhcp-config)# origin file tftp://10.1.0.1/static-bindings     for example.

 

I have two questions;

[1] does the url/protocol need to be tftp? or can it be 'anything' ?  (might be easier to get it from a webserver?)

[2] it is tftp, but does the file actually get transferred to the router, once?  Or does it check if the file was updated if it can connect to where that url lives?

 

thanks,

 

Ron

ok,  I probably stick it there.

 

I have dhcp working, although some wireless stuff didn't like the change from the 'old' to the 'new' router

I have some mixed results.

 

I am using Gi0/1 as a/the local LAN port.  The ip address was set with: "ip address 192.168.1.0 255.255.252.0"

(I have stuff that has an address in 192.168.1.0, 192.168.2.0 and 192.168.3.0)

I have one pool, "EVERYTHING-POOL" and that only that static binding file.

 

However, somehow some machines end up with an address like 192.168.0.x .  I have no idea why that happens, I don't want to do "any dynamic" DHCP only pre-determined IPs
