DHCP Troubleshooting
If the unit is unable to get the IP address from the DHCP server, check these areas:
The terminal shows a Boot>
prompt rather than a Local>
prompt.
The MSS is not connected
properly to the Ethernet.
Ensure that the MSS is firmly
connected to a functional and
properly-terminated network node.
The MSS Ethernet address is
invalid.
The MSS Ethernet address is located
on the bottom of the unit. Use the
Change Hardware command to set
the correct address (enter the last
three hex pairs of the address), then
reboot.
Init Noboot command was
entered.
See Entering Commands at the Boot
Prompt on page B-4.
The MSS passes power-up
diagnostics, but attempts to
download new Flash ROM code
from a network host.
If the OK LED blinks
rapidly, the Flash ROM code
may be corrupt.
Reboot the unit. If you get the same
message, you will need to reload
Flash ROM. See Reloading Software
on page D-1.
If you did not request a
TFTP boot, the flash ROM
code is corrupt. The unit will
remain in boot mode.
Table B-2: DHCP Troubleshooting
Area to Check Explanation
DHCP is enabled on the MSS. Use the Change Server DHCP Enabled command.
If you manually enter an IP address, DHCP is
automatically disabled.
The DHCP server is operational. Check to see that the DHCP server is on and is
functioning correctly.
The MSS is getting its IP address
from the DHCP server.
Refer to the DHCP Manager on your DHCP server
for information about addresses in use. If the DHCP
server doesn’t list your MSS IP address, there may be a
problem.
