OOB Switch Trunk Ports After Upgrade
Because Cisco NAC Appliance can control switch trunk ports for OOB (starting from release 3.6(1) and
above), uplink ports for managed switches need configured as “uncontrolled” ports either before or after
upgrade (see “Settings That May Change With Upgrade” in the corresponding Release Notes for Cisco
NAC Appliance.
This can be done in one of two ways:
• Before upgrading, change the Default Port Profile for the entire switch to “uncontrolled” under
OOB Management > Devices > Devices > List > Config [Switch_IP] > Default Port Profile |
uncontrolled
• After upgrading, change the Profile to “uncontrolled” for the applicable uplink ports of the switch
under OOB Management > Devices > Devices > List > Ports [Switch_IP] | Profile
This will prevent unnecessary issues when the Default Port Profile for the switch has been configured as
a managed/controlled port profile
If for some reason the above steps are omitted and the switch becomes disconnected, use the following
procedure:
Step 1 Delete the switch from the List of Switches in the CAM (under OOB Management > Devices > Devices
> List).
Step 2 Configure the switch using its CLI to reverse the changes made to the uplink port by the CAM (trunk
native VLAN and MAC change notification/MAC move notification), for example:
(config-if)# switchport trunk native vlan xxx
(config-if)# no snmp trap mac-notification added
Step 3 Add the switch back to the CAM (under OOB Management > Devices > Devices > New or Search),
applying “uncontrolled” as the Default Port Profile.
Step 4 Specifically assign the “uncontrolled” port Profile to the uplink port and other uncontrolled ports (under
OOB Management > Devices > Devices [x.x.x.x] > Ports).
Step 5 Reset the Default Port Profile for the switch (under OOB Management > Devices > Switches [x.x.x.x]
> Config).
Initialize the switch ports (under OOB Management > Devices > Devices [x.x.x.x] > Ports).
OOB Error: connected device <client_MAC> not found
Client connection errors can result from incorrect configuration of the switch profile. If attempting to
log into the network using the Agent, and the Agent provides the following error: “Login Failed! OOB
Error: connected device <client_MAC> not found. Please contact your network administration.”
