DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide Command Default Level Usage Guideline Level: 8 Both of the physical port and port-channel interfaces are valid for this command. This configuration will take effect on all the spanning-tree modes. A Boolean value set by management. If TRUE causes the Port not to propagate received topology changenotifications and topology changes to other Ports. This parameter should be FALSE by default. If set it can cause temporary loss of connectivity after changes in a spanning trees active topology as a result opersistent incorrectly learned station location information. It is set by a network administrator to prevent bridges external to a core region of the network, causing address flushing in that region, possibly because those bridges are not under the full control of the administrator or MAC_Operational for the attached LANs transitions frequently. Example This example shows how to configure TCN filtering.
