tmnxWlanGwMgwConnected
.1.3.6.1.4.1.6527.3.1.3.81.0.10
anGwMgwConnected notification is sent when this system adds
a conceptual row to the tmnxWlanGwMgwTable, or removes it.
[CAUSE] A connection is established between this system's WLAN Gateway
function and a Mobile Gateway, or such a connection disappears.
The interruption of a connection with a Mobile Gateway can be the
expected result of a management action on the Mobile Gateway, or it
can be caused by a network failure.
[EFFECT] While there is a connection with a particular Mobile Gateway,
User Equipment (UE) belonging to the associated PLMN (Public Land
Mobile Network) and serviced by this WLAN Gateway can be connected to
their Home PLMN.

anGwMgwRestarted notification is sent when this system
learns that a Mobile Gateway has restarted.
[CAUSE] A Mobile Gateway known to this system has restarted, has
transmitted its restart counter to this system and it was found to be
higher than its previously known value.
[EFFECT] This system clears all sessions associated with the restarted
Mobile Gateway (because that Mobile Gateway has lost its session data
anyway).
[RECOVERY] No recovery is required on this system.

tmnxWlanGwNumMgw indicates the actual number of Mobile Gateways
connected to this system.
The description below applies to the notification when sent with the
value of 'true'.
[CAUSE] The number of Mobile Gateways connected to this system is
approaching the maximum supported value.

Negotiated QoS profile RADIUS attribute contains a release indicator
either for GGSN or PGW that does not correspond to the interface type
actually used in GTP. e.g. the release indicator is for GGSN and the
interface type used in GTP is S2a/S2b while it should be Gn.
[CAUSE] Inconsistency between the release indicator in the RADIUS
attribute and the GTP interface type.
[EFFECT] The QoS values in the tmnxWlanGwPgwTable or the
tmnxWlanGwGgsnTable of the conceptual row corresponding to the row in
the tmnxWlanGwMgwAddrTable that matches the WLAN are used instead.
[RECOVERY] The RADIUS Server configuration should be corrected.

.1.3.6.1.4.1.6527.3.1.3.81.0.15
anGwSubIfRedActiveChanged notification is sent when the
value of the object tmnxWlanGwSubIfRedActive has changed.
[CAUSE] The tmnxWlanGwSubIfRedActiveChanged notification is sent when
the value of the object tmnxWlanGwSubIfRedActive changes. The cause is
explained in the tmnxWlanGwNotifyDescription.
[EFFECT] While the value of the object tmnxWlanGwSubIfRedActive is equal to 'false', ...
- this system is not performing Wifi Offload in the realm of this subscriber interface;
the Wifi Offload functionality is supposed to be performed by its redundant peer.
- this subscriber interface and all the group interfaces contained within this subscriber interface
are operationally down;
- for all group interfaces contained within this subscriber interface, the addresses
specified in tmnxWlanGwSoftGreIfGwAddr and tmnxWlanGwSoftGreIfGwV6Addr are
not advertised in the realm of the virtual router instance
where the tunneled User Equipment traffic is routed;
- the route specified with tmnxWlanGwSubIfRedExpPrefix is not exported
in the realm of the virtual router instance associated with this subscriber interface.
[RECOVERY] No recovery is required on this system.

anGwDsmGtpTunnelSetupFail notification is sent when a
problem occurred while trying to setup a GTP tunnel for a DSM
subscriber.
[CAUSE] A problem occurred while trying to setup a GTP tunnel for a
DSM subscriber.
This can be caused by:
- incomplete system configuration, or
- inconsistent RADIUS configuration, or
- because the GTP peer is not reachable.
[EFFECT] The DSM subscriber cannot establish a connection with his
home mobile network.
[RECOVERY] Depending on the cause, correct the system configuration,
the RADIUS configuration or the network connectivity.
