Use the 

dhcp 

command in the command line interface to configure the 

Vendor Class

, 

User Class

, and

 Client ID 

settings of the VCPS.

Each valid DHCP response contains options that provide the TCP/IP 
settings a VCPS needs to operate on a network and other information that 
affects the operation of the VCPS.

A VCPS uses the following options within a valid DHCP 

response to define its TCP/IP settings:

•

IP Address

 (from the 

yiaddr

 field of the DHCP response): The IP 

address that the DHCP server is leasing to the VCPS

•

Subnet Mask

 (option 1): The subnet mask value which the VCPS 

needs to operate on the network.

•

Default Gateway

 (option 3): The default gateway address, which the 

VCPS needs to operate on the network.

•

Address Lease Time

 (option 51): The time duration for the lease 

associated with the identified IP Address

.

•

Renewal Time, T1 

(option 58): The time that the VCPS must wait after 

an IP address lease is assigned before it can request a renewal of that 
lease.

•

Rebinding Time, T2 

(option 59): The time that the VCPS must wait 

after an IP address lease is assigned before it can seek to rebind that 
lease.
