 System Diagnostics

4 - 3

To view the networking configuration and status of the 4300T proceed to the 

Network Information page as follows: 

Select System.

Select System Overview.

Select Network Information.

The following networking information is displayed:

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 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.

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.
