Advanced Switch Functions
Spanning Tree Support
To support spanning tree, the host port is the designated port for the processor.
The other ports can be configured in one of the five spanning tree states via “transmit enable”, “receive enable” and
“learning disable” register settings in registers P1CR2 and P2CR2 for ports 1 and 2, respectively. Table 9 shows the port
setting and software actions taken for each of the five spanning tree states.
Disable State
Port Setting
Software Action
The port should
not forward or
receive any
packets. Learning
is disabled.
“transmit
enable = 0,
receive
enable = 0,
learning
disable =1”
The processor should not send any packets to the port. The switch may still
send specific packets to the processor (packets that match some entries in
the “static MAC table” with “overriding bit” set) and the processor should
discard those packets. Address learning is disabled on the port in this
state.
Blocking State
Port Setting
Software Action
Only packets to
the processor are
forwarded.
“transmit
enable = 0,
receive
enable = 0,
learning
disable =1”
The processor should not send any packets to the port(s) in this state. The
processor should program the “Static MAC table” with the entries that it
needs to receive (for example, BPDU packets). The “overriding” bit should
also be set so that the switch will forward those specific packets to the
processor. Address learning is disabled on the port in this state.
Listening State
Port Setting
Software Action
Only packets to
and from the
processor are
forwarded.
Learning is
disabled.
“transmit
enable = 0,
receive
enable = 0,
learning
disable =1”
The processor should program the “Static MAC table” with the entries that it
needs to receive (for example, BPDU packets). The “overriding” bit should
be set so that the switch will forward those specific packets to the
processor. The processor may send packets to the port(s) in this state.
Address learning is disabled on the port in this state.
Learning State
Port Setting
Software Action
Only packets to
and from the
processor are
forwarded.
Learning is
enabled.
“transmit
enable = 0,
receive
enable = 0,
learning
disable = 0”
The processor should program the “Static MAC table” with the entries that it
needs to receive (for example, BPDU packets). The “overriding” bit should
be set so that the switch will forward those specific packets to the
processor. The processor may send packets to the port(s) in this state.
Address learning is enabled on the port in this state.
Forwarding State
Port Setting
Software Action
Packets are
forwarded and
received normally.
Learning is
enabled.
“transmit
enable = 1,
receive enable
= 1, learning
disable = 0”
The processor programs the “Static MAC table” with the entries that it
needs to receive (for example, BPDU packets). The “overriding” bit is set so
that the switch forwards those specific packets to the processor. The
processor can send packets to the port(s) in this state. Address learning is
enabled on the port in this state.
