DHCP Client networking 

 

6.1.2 Preparing for configurations

 

Scenario 

As a DHCP client, the ISCOM2600G-HI series switch obtains the IP address from the DHCP 
server. 

The IP address assigned by the DHCP client is limited with a certain lease period when 
adopting dynamic assignment of IP addresses. The DHCP server will take back the IP address 
when it is expired. The DHCP client has to renew the IP address for continuous use. The 
DHCP client can release the IP address if it does not want to use the IP address before 
expiration. 

We recommend configuring the number of DHCP relay devices smaller than 4 if the DHCP 
client needs to obtain IP address from the DHCP server through multiple DHCP relay devices. 

Prerequisite 

 

Create VLANs 

 

Add the Layer 3 interface to the VLANs. 

 

DHCP Snooping is disabled. 

 

FE 1/0/1 supports obtaining the IP address through DHCP or zero-configuration. 

6.1.3 Default configurations of DHCP Client

 

Default configurations of DHCP Client are as below. 

Function 

Default value 

hostname 

Raisecom 

class-id 

Raisecom-ROS 

client-id 

Raisecom-SYSMAC-IF0
