    Troubleshooting NSM4000 Ethernet Interface eth0 Connectivity


    If you have connectivity issues with the NSM4000 Ethernet interface eth0, you can use this procedure to troubleshoot the connectivity issues.


    Before you begin:

    • Connect a management device (PC or laptop) to the appliance using the management console and power on both the appliance and the management device. Alternatively, you can connect to the appliance via telnet or SSH if the appliance is accessible via the network.
    • Log in to the appliance using the administrator username (admin) and password.

    To troubleshoot connectivity issues from the eth0 interface:

    1. Enter the ifconfig eth0 command to verify that the IP address is correctly assigned to the eth0 interface.
    2. Enter the ping <NSM4000 IP address> command on the management device (laptop or PC) to verify the communication between the NSM4000 appliance and the management device.
    3. If no packets are received:
      • Verify the gateway IP address in the devint routing table by executing the following command from the shell:

        ip route show table devint

        The gateway IP address should be the one configured for routing device management traffic. See “Setting Routing Options” in Configuring Standard Configuration Options for information about changing the default gateway for device management traffic.

      • Check the physical connectivity of Ethernet interface eth0.
