Abstract

During operation, the port management module identifies a local port selected to be in a blocking state associated with a spanning tree. The notification module constructs a notification message associated with the blocking state.
Claims20
A switch, comprising:
- a port management module configurable to identify a local port selected to be in a blocking state associated with a spanning tree;
- and
- a notification module configurable to construct a notification message associated with the blocking state.
A switch, comprising:
- a packet processor configurable to extract from a notification message a blocking state of a port in a remote switch, wherein the blocking state is associated with a spanning tree;
- and
- a flow control module configurable to suppress flooding via a local peer port of the port in the remote switch in response to extracting the blocking state.
A method, comprising:
- identifying, by a switch, a local port selected to be in a blocking state associated with a spanning tree;
- and
- constructing a notification message associated with the blocking state.
A method, comprising:
- extracting, by a switch, from a notification message a blocking state of a port in a remote switch, wherein the blocking state is associated with a spanning tree;
- and
- suppressing flooding via a local peer port of the port in the remote switch in response to extracting the blocking state.
