Configuring TC snooping
shows a topology change (TC) snooping application scenario. Device does not have the
spanning tree feature enabled. Device connects to two user networks, in which all devices are
enabled with the spanning tree feature. The user networks are dual-uplinked to Device for high
availability. Device transparently transmits BPDUs in every user network.
