This event is sent by Link Aggregation NI when a physical port is joining an aggregator; It could be either 
a static aggregator (OmniChannel) or a dynamic aggregator (802.3ad). This message is generated after the 
first port has joined the aggregator (see 

).

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.

This event is sent by Link Aggregation NI when a physical port is leaving an aggregator; It could be either 
a static aggregator (OmniChannel) or a dynamic aggregator (802.3ad). This message is generated after the 
first port has joined the aggregator (see 

). Link aggregation provides the aggre-

gator identifier, the global port identifier of the port which is leaving it and the global port identifier of the 
newly primary port

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 global port identifier of the physical port that will have the primary port role.

• Fourth parameter: The output QID of the newly primary port (not significant; see note of 

The is event is generated by the Spanning Tree CMM when a configuration parameter of the Spanning 
Tree is changed by the operator. This message is sent to all the NI that are up and running.

The parameters are:

• First parameter: The spanning identifier (i.e., VLAN identifier).

• Second parameter: The type of the parameter. A 1 indicates Spanning Protocol (802.1w(third parame-

ter=4)/802.1D(third parameter=3)), a 2 indicates Spanning Tree (Flat (third parameter=1)/ or 1x1 (third 
parameter=2)/), a 3 indicates the bridge priority value, a 4 indicates the Hello timer value, and a 5 indi-
cates the forward delay value, and a 6 indicates the maximum age.

• Third parameter: The value of the parameter.
