Re: [OSL | CCIE_Voice] DHCP server just one pool on router
The reason I use ip dhcp database, is to generate the file in the correct format with the correct phone mac identifiers. My process works like this: Set up the dhcp pool as normal Generate a database file for the addresses learned in the existing pool Copy the database file, changing the addresses and lease expirations Add the new file to the router Under the dhcp pool change network to origin file For me this is the easiest way, I don't have to worry about the format of the file as the router generated it, I am just changing addresses and expiration times Hope this helps Jamie Parr Engineer - IT jamp...@cisco.commailto:jamp...@cisco.com Phone: +44 20 8824 2641 Mobile: +44 7590622049 From: ikizoo4 kwon [mailto:ikiz...@hotmail.com] Sent: 15 March 2013 17:30 To: Chrysostomos Christofi; Jamie Parr (jamparr); sanity insanity; ccie_voice@onlinestudylist.com Subject: RE: [OSL | CCIE_Voice] DHCP server just one pool on router Hi Jamie, i thought i verified this questions before, but what is purpose of ip dhcp database, first database file and etc could you provide any detail for reason being? i think below is enough to work .

The requirement is that just 1 dhcp pool is required for the phone. I am also asked to assign ip addresses of 14.10.66.13 and 14.10.66.14 for my phones. Current I have the following config on the router but I am forced to have 2 pools. ip dhcp pool S1 host 14.10.66.13 255.255.255.0 client-identifier 01a9.ef64.9f52.0d default-router ip addr of sc router option 150 ip ip addr of cucm ip dhcp pool S2 host 14.10.66.14 255.255.255.0 client-identifier 0108.26d8.3b68.achttp://0108.26d8.3b68.ac option 150 ip ip addr of cucm default-router ip addr of sc router The above config works but is this the right way since only 1 pool is required? Could you elaborate the correct process that needs to be followed ? -MJ ___ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?
