Polycom V2IU 4350 user manual Routing Information

System Diagnostics

To view the networking configuration and status of the 4350 proceed to the Network Information page as follows:

1.Select System.

2.Select System Overview.

3.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 4350. 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 4350 loopback interface

•The 4350’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 4350.

Link status for the Ethernet ports is displayed via the LEDs adjacent to each physical port.

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 4350 processor and the built-in LAN switch. Interface statistics for the external LAN ports are not displayed.
