Unable to connect to a supported log device
After configuring logging to a supported log device, and testing the connection, you may find you cannot connect. To determine whether this is the problem:
1. Verify that the information you entered is correct; it could be a simple mistake within the IP address or you may have not selected Apply on the Log Settings page after changing them, which would prevent them from taking effect.
2. Use execute ping to see if you can ping to the log device.
3. If you are unable to ping to the log device, check to see if the log device itself working and that it is on the network and assigned an appropriate address.
