DHCP-client configuration tasks

SmartWare Software Configuration Guide 

After enabling the DHCP-client, the interface receives a DHCP lease from the DHCP-server. To manually 
release and/or renew this DHCP lease use the command described below.

This procedure describes how to release and renew the DHCP lease

Mode: interface

If you are connected by Telnet over the IP interface on which you release the 
DHCP lease, the connection is lost after entering the command 

. You need an other way (e.g. a serial connection) to connect to the 

SmartNode again and to enter the command 

!

This procedure describes how to enable/disable DHCP-client debug monitor

Mode: Any

Example: Enable DHCP debug monitor

This example shows how to enable the DHCP-client debug monitor and the debug output of the command 

 and
