Installing the CNR LEG on Windows

Note The directory in which the CNR is installed is referred to as cnr-inst-dir.

SUMMARY STEPS

1. Extract the SM LEG distribution file

2. Locate the CNR LEG distribution tar file under the CNR LEG directory

3. Extract the CNR LEG distribution and copy the files

4. Configure the CNR LEG using the sample configuration file

5. Configure the SM

6. Register the CNR LEG with the CNR

DETAILED STEPS

Step 1 Extract the SM LEG distribution file

Step 2 Locate the CNR LEG distribution tar file under the CNR LEG directory

Step 3 Extract the CNR LEG distribution and copy the files

•Unzip the CNR Package to pkg-ext-dir.

•Copy all files under pkg-ext-dir\winnt to <cnr-inst-dir>\Extensions\DHCP\Dex\.

•Copy the sample configuration file from pkg-ext-dir\doc to a directory of your choice, hereafter referred to as cfg-dir.

Step 4 Configure the CNR LEG using the sample configuration file

See Information About Configuring the CNR LEG.

Step 5 Configure the SM

See Information About Configuring the SM.

Step 6 Register the CNR LEG with the CNR

•Run the CNR <cnr-inst-dir>/bin/nrcmdcommand-line utility.

•Log in to the CNR nrcmdCLU.

To log in, type the following command:

nrcmd[-C cluster] [-N user] [-P password]
•Configure the following:

nrcmd>extension smleg create dex cnrleg.dll cnrLegPostSendPacket
nrcmd>extension smleg set init-entry=cnrLegInitEntry
nrcmd>extension smleg set init-args=cfg-dir/cnrleg.cfg
nrcmd>dhcp attachExtension post-send-packet smleg 1
Any sequence number can be used for this command
nrcmd>extension smlegext create dex cnrleg.dll cnrLegPostPacketDecode
nrcmd>dhcp attachExtension post-packet-decode smlegext 1
Any sequence number can be used for this command
nrcmd>save
nrcmd>server DHCP reload

Note You must use the cfg-dir full path in the init-args argument.

Note You must use a slash ("/") and not a back-slash ("\") as the path separator.
