PORTJOIN
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 “AGGR_UP” on page 4-13).
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.
PORTLEAV
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 “AGGR_UP” on page 4-13). 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 “AGGR_UP”
on page 4-13).
BRGPARAM
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.
