Cisco CNR Question Please

Good day,

Using Cisco CNR I can configure a cable modem and it gets its IP and .cm file
Behind that cable modem is a host that I want to make an ip to mac reservation and then send a file to the host right after dhcp using tftp.

this is what it would look like using a linux dhcp server (snip from dhcpd.conf)

(Note this is in a lab environment so the IP's are not public)

Can someone send me the screen shot for how this same thing would be accomplished using Cisco CNR - Not sure what version off the top of my head.

I do not believe this can be

I do not believe this can be accomplished in the gui. In cisco CNR this is a two step process,

1. reserve the IP address (GUI - CLI)
2. set the client policy (CLI only)

Via the CLI you can reserve the ip fairly easily check online docs for exact verbage.

to set the config file per client you would do

client-policy [MAC_ADDRESS] setOption [OPTION] [VALUE]

i.e.
client-policy 0000.0000.0000 setOption routers 192.168.100.1

There is a priority for policies in CISCO CNR

Generic Poilcy policy [Name] setOption
Scope policy scope-policy [Name] setOption
Client policy (highest priority) client-policy [Name] setOption

re: Cisco CNR Question Please

You should contact cisco for support of CNR, why else would you shell out money for it?
