Technical Support (see "Before You Contact
Technical Support" on page 142).
IMPORTANT: Make sure you have the following
information on hand before calling:
• Setup scenario
• Is there a common dnominator (router, only one
side of subnet, etc.)
• Other call scenarios (Ip to IP, IP to TDM, etc.)
• Layer 2 switch configuration and settings
• Router configuration and settings
• Network diagram
• IP addressing scheme
• VLAN configuration and settings
• Layer 2 switch port statistics for FCS, collision and
duplex mismatch
Probable cause
No gateway IP
address programmed
on E2T.
Corrective Action
1.
If E2T gets IP address
from DHCP server, make
sure that Option 03
(Router) is assigned to
the scope with the proper
IP address for the
subnet.
2.
If E2T is hardcoded
with a static P address,
make sure that the
gateway IP address is
programmed properly in
VxWorks.
