PTSTPMOD
The is event is generated by the Spanning Tree CMM when the Spanning Tree configuration parameter of
a port is changed by the operator.
a port is changed by the operator.
The parameters are:
• First parameter: The spanning identifier (i.e., VLAN identifier).
• Second parameter: The global port identifier.
• Third and fourth parameters: The type of the parameter/value. A 0x11 indicates mode of the port
(dynamic(1), blocking(2), forwarding(3)), a 0x12 indicates Spanning Tree administrative state of the
port (enable(1),disable(2)), a 0x13 indicates port administrative state, a 0x14 indicates port priority, a
0x15 indicates port path cost, and a 0x16 indicates port connection type (half-duplex(1),point to point
(2),auto point to point(3),edge(4)).

PORTMOD
The is event is sent by the Spanning Tree CMM to the Spanning Tree NI when the administrative state of
a port is modified by the operator.
a port is modified by the operator.
The parameters are:
• First parameter: The spanning identifier (i.e., VLAN identifier).
• Second parameter: The global port identifier.
• Third and fourth parameters: The type of the parameter/value. A 0x13 indicates port administrative
state (enable (1),disable(2)).
PORTVLBK
This event is an internal event which generated by the Spanning Tree when STP is processing a Port/
VLAN blocking that can take place at VLAN level or port level.
VLAN blocking that can take place at VLAN level or port level.
The parameters are:
• First parameter: The blocking status. A 0x44 indicates blocking already done, a 0x88 indicates nothing
to do, a 0x55 indicates blocking at port level, and a 0xaa indicates blocking at VLAN level.
• Second parameter: The local port identifier.
• Third parameter: The VLAN identifier.
PVLANBLK
This event is registered when the Spanning Tree is generated a Port VLAN Blocking message to Source
Learning NI.
Learning NI.
The parameters are:
• First parameter: The VLAN identifier.
• Second parameter: The port vector.
• Third parameter: The local port identifier.
