[. . . ] Usage tips It is important that your Ethernet settings match those of the device to which this port is connected. For example, both devices must be configured to use automatic negotiation, or both configured with fixed and matching speed and duplex settings (see below). Manual configuration Speed Identifies the connection speed: 10 Mbit/s or 100 Mbit/s. Use automatic negotiation if a connection speed of 1000 Mbit/s is required. The connection speed must match that of the device to which this port is connected. You only need to select this option if you have chosen manual Ethernet settings, as described above. The duplex setting must match that of the device to which this port is connected. You only need to select this option if you have chosen manual Ethernet settings, as described above. Duplex Identifies the connection duplex mode: Full duplex Both devices can send data to each other at the same time Half duplex Only one device can send to the other at a time Ethernet status Field Link status Field description Indicates whether this Ethernet port is connected to or disconnected from the network. The speed (10/100/1000 Mbit/s) of the network connection to the ISDN gateway on this port. This value is negotiated with the device to which this port is connected or based on your manual configuration, depending on the settings you chose above. This value is negotiated with the device to which this port is connected or based on your manual Usage tips Speed Duplex The duplex mode (full/half duplex) of the network connection to this port. Cisco TelePresence ISDN Gateways v2. 0 Online help (Printable format) 54 of 116 Configuring network settings configuration, depending on the settings you chose above. MAC address Packets sent The fixed hardware MAC (Media Access Control) address of this port. Displays a count of the total number of packets sent from this port by the ISDN gateway. When troubleshooting connectivity issues, this information can help you confirm that the unit is transmitting packets into the network. When troubleshooting connectivity issues, this information can help you confirm that the unit is receiving packets from the network. Use these fields for advanced network diagnostics, such as resolution of problems with Ethernet link speed and duplex negotiation. Packets received Displays a count of the total number of packets received by this port of the ISDN gateway. This includes all TCP and UDP traffic. Statistics The fields display further statistics for this port. Multicast packets sent Multicast packets received Total bytes sent Total bytes received Receive queue drops Collisions Transmit errors Receive errors Cisco TelePresence ISDN Gateways v2. 0 Online help (Printable format) 55 of 116 Configuring IP routes settings Configuring IP routes settings You need to set up one or more routing settings to control how IP traffic flows in and out of the ISDN gateway. It is important that these settings are configured correctly, or you may be unable to make calls or access the web interface. In this section: Port preferences IP routes configuration Port preferences If both Ethernet ports are enabled, it is necessary to specify which port is used in certain special circumstances. Make the appropriate selections described below; click Apply changes to make any changes take effect. Field Default gateway preference Field description The IP address to which the ISDN gateway will send packets in the absence of more specific routing (see IP routes configuration). Therefore, it only makes sense to have precisely one default gateway, even though different default gateways may have been configured for Ports A and B. Use this option to decide which port's default gateway configuration to use as the unit's default gateway. [. . . ] However, we recommend that you upload your own certificate and private key to ensure security as all ISDN gateways have identical default certificates and keys. To upload your own certificate and key, go to Network > SSL certificates, complete the fields and click Upload certificate and key. After uploading a new certificate and key, you must restart the ISDN gateway. If you have uploaded your own certificate and key, you can remove it later if necessary; to do this, click Delete custom certificate and key. [. . . ]
