You must perform a full configuration update for each device on which you want to
enable netdump.
If an AP or switch becomes non-responsive, you can enable it to automatically save a
core dump file to a TFTP server on the network the next time it boots. You can
provide this file to Support to assist in diagnosing the issue. To configure a
device to save a core dump file to a TFTP server, complete the following steps:
-
Select the check box to enable
Netdump.
-
Enter the IP address of the TFTP server to where you want the device to send
the core file.
-
Name the netdump file.
-
Enter the VLAN of the interface
the device will use to send the netdump file to the TFTP server.
-
Enter the native VLAN of the device.
-
Select the check box to have the device bootloader use DHCP to obtain an IP
address at startup.
-
Select the check box to expand this section.
-
Enter the required network settings that the bootloader must use to connect to
the network.
-
Enter the IP address of the reporting device.
-
Enter the netmask for the reporting device.
-
Enter the IP address of the TFTP server.
-
Select Save.
-
To update the device immediately, select Update
Now.
-
Select the type of update.
-
Select Save as Defaults.
-
Select Perform Update.
The device will send a core dump file to the TFTP server the next time it
reboots.
