General DHCP Troubleshooting

What happens if the DHCP server cannot be contacted?

Serial Interface: the following occurs over the serial line: the following text

appears above the Main menu within the hyperterminal window,

“Attempting to contact DHCP server…” After about 3 minutes, the

following message appears,

“Can't renew DHCP boot lease.”

Within Telnet: the user will see only a blank Telnet window which is not

accessible. Instead of an IP address value displaying in the upper left heading

of the Telnet window,

“(None)” appears instead. Within half a minute, Telnet

will produce a warning message stating

“Connect Failed!”

Within HTTP: the user will be able to submit a new web page and reboot (as is

typically the case). However, since the DHCP isn't contacted, a new IP address

will not be generated after reboot. Therefore, HTTP will no longer be useful

since no IP address is available. The previous non-DHCP will not work either.

HTTP will time out and provide a warning message to the user stating that

“a

connection with server could not be established.”
