Troubleshooting Software Errors
DHCP
Invalid TFTP
information
received from
DHCP server
Although the VG248
received TFTP
information from the
DHCP server, it was not
valid.
The VG248 might not
have enough
information to retrieve
telephony port
configuration or register
with
Cisco CallManager.
Check configuration of DHCP server. If
errors persist, assign a static IP address and
manually enter settings for the TFTP server.
Refer to the
“Configuring Network
Settings” section on page 2-4
for details on
assigning a static IP address.
DNS
No response
from primary
server
The DNS server failed
to respond to one or
more requests from the
VG248.
1.
If the VG248 has a static IP address,
verify the DNS server has been
configured. Refer to the
“Setting the
DNS Server” section on page 2-9
for
details.
2.
Verify that the DNS server is working
properly.
DNS
Server address
not configured
A DNS query has been
attempted, but no DNS
server has been
configured.
1.
If the VG248 has a static IP address,
verify the DNS server has been
configured. Refer to the
“Setting the
DNS Server” section on page 2-9
for
details.
2.
If you are using DHCP, the DHCP
server has not provided a DNS server.
Check the DHCP server configuration.
FTP
Invalid
password
entered
An attempt was made to
connect to the VG248
via FTP with the wrong
password.
Verify that you have entered the password
for the highest level of security currently
set. When using FTP, if you have both a
login and an enable password set, you must
use the enable password.
Refer to the
“Configuring Passwords”
section on page 2-11
for details.
