Viewing Networking Information
To view the networking configuration and status
of the 4300T proceed to the Network
Information page as follows:
A. Select System.
B. Select System Overview.
C. Select Network Information.
The following networking information is displayed:
Routing Information
The system routing table contains the static
routes for hosts and networks that are configured
on the 4300T. If just the LAN and WAN IP
addresses have been configured there will be four
lines displayed:
 The private subnet will be associated with the LAN interface.
 A public subnet present for the WAN interface.
 An entry for the 4300T loopback interface
 The 4300T’s default gateway forwarding to the WAN interface
Additional lines may be displayed depending on the contents of the Route and VoIP
Subnet Routing pages. Each of the entries on these pages will cause an additional
entry in the routing table.
Link Status
Link Status displays the status of the ethernet interfaces. Ethernet autonegotiation is
often unreliable, especially between different vendors or old and new networking
equipment. Failure of autonegotiation is generally not a cause for concern.
However, if the negotiated rates change intermittently or the link is reported as
down or no link, the link rate may need to be set manually on the Set Link Rate
page. Intermittent data and voice outages may be caused by link “flapping” when
the two endpoints of the Ethernet cable cannot reach agreement using
“autonegotiation". If the link rate is set manually, ensure that the device at the far
end of the connection can communicate at the desired rate. Incompatible rates can
cause a loss of communication with the 4300T.
Link status for the Ethernet ports is displayed via the LEDs adjacent to each physical
port.d
Interface Information
The specific status and configuration information for the system interfaces is
displayed in the Interface Information section. HDLC0 shows the interface statistics
for the T1/E1 WAN link. ETH0 shows the interface statistics for the internal LAN
interface between the 4300T processor and the built-in LAN switch. Interface
statistics for the external LAN ports are not displayed.
The interface statistics can point to areas of congestion in the network. If the errors
statistic is a few percent or more of the total packets sent it may be an indication of
