These concepts are explained below.

14.10.1 DHCP Provisioning

14.10.1.1 iMGs/RGs at Release 3-x

As explained in 14.1.4, the iMG/RG, DHCP server, and AlliedView NMS use DHCP to provide provisioning information and

to download files until the iMG/RG and its network connections are recognized so that services can be supported. This is

still done, as shown in Figure 14-186, but the following is changed.

• Provisioning is tied to the MAC address of the iMG/RG, and must be known before provisioning.

• At the NMS, the RGbootConfigurator must be filled out with TFTP Discovery Enabled. When selected, after the RG

reboots it sends a DHCP discovery message to the DHCP server (over the RGMgmt VLAN). The iMG/RG then sends a

tftp request to the NMS, containing its MAC and IP address. The NMS uses its tftp listener to discover the iMG/RG with

this MAC and IP Address. With the IP and MAC Address, the AlliedView NMS can proceed with discovery and

provisioning.

Note: With the iMG/RG provisioned with a specific MAC address, the iMG/RG cannot simply be swapped with another one when

performing provisioning or maintenance and having the NMS automatically provision the new iMG/RG. At the NMS, the

administrator must delete all objects or traces so that the iMG is no longer known to the NMS. You would then start

provisioning from the beginning, by knowing the MAC address of the new iMG.

• The dhcpd.conf file must include the NMS IP address.

Refer to Figure 14-186, which shows the steps that are followed

iMG/RG

AlliedView NMS

Step 1

Step 2

iMG/RG request for Boot IP Address and TFTP Server IP Address

Step 3,4

DHCP Server returns information

iMG/RG downloads new software and base config file ( includes ZTC Enabled and Mgmt VLAN configured)

iMG/RG reboots using new configuration

Step 5

Step 6

Step 7

iMG/RG requests Mgmt IP Address and NMS IP Address (=ZTC Server Address) from DHCP Server

Step 8

DHCP Server returns information

NMS has IP/MAC Address mapping, begins provisioning

iMG/RG sends ZTC-like TFTP request to NMS (includes IP and MAC address)

Step 9

DHCP Server

Pre-provision:

- Fill out MAC Address of the iMG/RG on the Triple Play form

- RGbootConfigurator set up with Download file with TFTP Enable

- dhcpd.conf has NMS IP Address
