Troubleshooting NSM4000 Ethernet Interface eth0 Connectivity
Purpose If you have connectivity issues with the NSM4000 Ethernet interface eth0, you can use
this procedure to troubleshoot the connectivity issues.
Action 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
