Get Debug Output From Dhcp-Client - Patton electronics SmartNode Series Software Configuration Manual

SmartWare Software Configuration Guide
Mode: interface
Step
1 node (if-ip)[ name ]#dhcp-client release
2 node (if-ip)[ name ]#dhcp-client renew
Note
If you are connected to the SmartNode by telnet over the IP interface on
which you release the DHCP lease, the connection has lost after entering the
command dhcp-client release. You need an other way (e.g. a serial connec-
tion) to connect to the SmartNode again and to enter the command dhcp-
client renew!
