This event is received is sent by the Spanning Tree CMM to the NI when the default VLAN of a fixed or 
q-tagged port is change (this also applies to logical port). This event is generated on the CMM by VLAN 
Manager application.

The parameters are:

• First parameter: Global port identifier.

• Second parameter: new default VLAN.

This event is currently unused.

This event is currently unused.

This event is sent by Link Aggregation NI when it detects that a aggregator comes up; It could be either a 
static aggregator (OmniChannel) or a dynamic aggregator (802.3ad). This message is generated when the 
first port joins the aggregator only.

The parameters are:

• First parameter: The aggregator identifier (logical port ID value between 0 and 31).

• Second parameter: The global port identifier of the physical port that has joined the aggregator.

• Third parameter: The output QID to be used by the Spanning Tree (not significant).

Note. The output QID is no more used by the Spanning Tree since at the time Link aggregation is asking 
for the default queue associated to the physical port, Qdriver might not be ready the provide it. However 
Link Aggregation keeps providing this parameter even if now this one is not significant.

This event is sent by Link Aggregation NI when it detects that a aggregator goes down; It could be either a 
static aggregator (OmniChannel) or a dynamic aggregator (802.3ad). This message is generated when the 
last port has leaved the aggregator.

The single parameter is:

• First parameter: The aggregator identifier (logical port ID value between 0 and 31).
