Viewing Networking Information
To view the networking
configuration and status of the
4200 proceed to the Network
Information page as follows:
A. Select System.
B. 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 4200. If just
the LAN and WAN IP addresses
have been configured there will
be multiple lines displayed:
 The private subnet will be associated with the LAN interface.
 A public subnet present for the WAN interface.
 An entry for the 4200 loopback interface
 An entry for each IPSec tunnel
 The 4200’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 4200.
Interface Information
The specific status and configuration information for the system interfaces is
displayed in the Interface Information section.
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
excessive congestion on the network interface. If the congestion is not corrected the
quality of voice calls will be affected. The topology of the network attached to the
