If you experience problems getting your Sensor and Manager to communicate, it might be a communication issue between the Sensor's Management port and the network device to which it is connected. Check the Management Port Link indicator lights on the Sensor. If the link is down, see if any of the following suggestions enable connectivity.
Check that the network device is online.
Check the cable connecting the Sensor to the network device.
Ensure that the port on the device to which the Management port is connected is enabled and active.
The port speed and duplex mode of the two devices must match. For example, if the device connecting to the Sensor is not set to auto-negotiate, you must configure the Management port to use the same settings as those of the device connecting to the Management port. To troubleshoot this, use the
set mgmtportcommand.Note
Check the link LEDs on the devices to see if communication is established, or use the
show mgmtportcommand to show the link's status.
Try each of these configuration options to see if one establishes a link:
If possible, set the other device's port configuration to auto-negotiate. (The Sensor is set to auto-negotiate by default.)
Using the
set mgmtportcommand as described below in Setting the management port speed and duplex mode, try setting the speed and port of the Sensor tospeed 100andduplex half or full.If no link is established, try
speed 10andduplex half or full.If none of these attempts creates a link, try setting the port on the other device to a speed of 100, duplex half or full, and try step 2 again.
If this does not establish a link, you can then do the same, setting the other device to a speed of 10, duplex half or full, and try step 3 again.
