Firewall between the devices
If there is a firewall between the Sensor and the Manager server, make sure the devices
are able to communicate by opening the appropriate ports.
Note :
Ports used by the Manager server are listed in the section Install a desktop
firewall. (on page

Management port configuration
If you experience problems getting your Sensor and Manager to communicate, it may be a
communication issue between the Sensor’s Management port and the network device to
which it is connected. Check the Management Port Link LEDs on the Sensor; if the link is
down, see if any of the following suggestions enable connectivity.
Check that the network device is on-line.
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/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 mgmtport
command.
Note:
Check the link LEDs on the devices to see if communication is
established, or use the
show mgmtport
command to show the link’s status.
Try each of these configuration options to see if one establishes a link:
1
First (if possible) set the other device’s port configuration to auto-negotiate. (The
Sensor is set to auto-negotiate by default.)
2
Using the
set mgmtport
command as described below in
Setting the management
port speed and duplex mode
,
try setting the speed and port of the Sensor to
speed
100
and
duplex half or full
.
3
If no link is established, try
speed 10
and
duplex half or full
.
4
If none of the above 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.
5
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.
6
If you are still experiencing difficulties, contact McAfee Technical Support.
Note:
M series Sensors Management port support 1000 Mbps(1Gbps)too.Use the
set mgmtport auto
command to establish a link to the connecting device(before
performing this,see to it that the other device's port configuration's speed is fixed to
1000 and also set to auto-negotiate).
