Aruba Controller Traps
Table 26 provides a list of key traps generated by the Aruba controller.
Table 26 Key SNMP Traps of the Aruba Controller
Trap Description Priority Level
Mobility controller IP
changed
This indicates the controller IP has been changed. The controller IP is either the
loopback IP address or the IP address of the VLAN 1 interface (if no loopback IP
address is configured).
Critical
Mobility controller role
changed
This indicates that the controller has transitioned from being a master controller to a
local controller or vice versa.
Critical
User entry created/
deleted/authenticated/de-
authenticated/
authentication failed.
Each of these traps are triggered by an event related to a user event. The event can be
a new user entry being created in the user table, deletion of a user entry, a user getting
authenticated successfully, a user getting de-authenticated, or a failed authentication
attempt. Each of these traps will be generated by the controller on which the user
event occurs. In other words this is a local event to the controller where the user is
visible.
Medium
Authentication server
request timed out.
This trap indicates that a request to a authentication server did not receive a response
from the server within a specified amount of time and therefore the request timed out.
This usually indicates a connectivity problem from the Aruba controller to the
authentication server or some other problem related to the authentication server.
High
Authentication server
timed out
NOTE: Earlier versions of ArubaOS supported SNMP on individual APs. This feature is
not supported by this version of ArubaOS. This trap indicates that an authentication
server has been taken out of service. This is almost always same as
AuthServerReqTimedOut except when there is only one authentication server in
which case the server will never be taken out of service. In that case the
AuthServerReqTimedOut will continue to be raised but not then
AuthServerTimedOut.
High
Authentication server up This trap indicates that an authentication server that was previously not responding
has started responding to authentication requests. This will be triggered by a user
event that causes the controller to send an authentication request to the
authentication server.
Low.
Authentication user table
full
This trap indicates that the authentication user table has reached its limit with the
number of user entries it can hold. This event is local to the controller that generates
the traps. The maximum number of user entries that can be present at the same time
in the user table is 4096.
Critical
Authentication Bandwidth
contracts table full
This trap indicates that the maximum number of configured bandwidth contracts on
the controller has been exceeded. The threshold for this is 4096
High
Authentication ACL table
full
This trap indicates that the maximum number of ACL entries in the ACL table has
been exceeded. The limit for this is 2048 entries on a controller.
High
Power supply failure As the name indicates, this trap indicates the failure of one of the two possible power
supplies in the controller.
Critical
Fan failure As the name indicates, this trap indicates a failure of the fan in the controller. Critical
Out of Range Voltage This trap indicates an out of range voltage being supplied to the controller. Critical
Out of Range temperature This trap indicates an out of range operating temperature being supplied to the
controller.
Critical
Line card inserted/
removed
These traps indicate that a Line Card has been inserted or removed from the
controller.
Critical.
Supervisor card inserted/
removed
These traps indicate that a Supervisor card has been inserted or removed from the
controller
Critical
Power supply missing This trap indicates that one of the power supplies is missing. Critical
