STS16DuplicateBridge

This trap is generated when a duplicated bridge number is detected on a port in a CRF.

STS16RingNumberMismatch

This trap is generated when a mismatch in ring numbers is detected on a port in a CRF.

Traps for the Spanning Tree Protocol

STS16TrCRFNewRoot

This trap is a CRF specific version of the newRoot trap as described in RFC1493. The newRoot trap indicates that the sending agent has become the new root of the spanning tree; the trap is sent by a bridge soon after its election as the new root, for example, upon expiration of the Topology Change Timer immediately subsequent to its election.

STS16TrCRFTopologyChange

This trap is a CRF specific version of the topologyChange trap as described in RFC1493. A topologyChange trap is sent by a bridge when any of its configured ports transitions from the Learning state to the Forwarding state, or from the Forwarding state to the Blocking state. The trap is not sent if a newRoot trap is sent for the same transition.

STS16TrBRFNewRoot

This trap is a BRF specific version of the newRoot trap as described in RFC1493. The newRoot trap indicates that the sending agent has become the new root of the spanning tree; the trap is sent by a bridge soon after its election as the new root, for example, upon expiration of the Topology Change Timer immediately subsequent to its election.

STS16TrBRFTopologyChange

This trap is a BRF specific version of the topologyChange trap as described in RFC1493. A topologyChange trap is sent by a bridge when any of its configured ports transitions from the Learning state to the Forwarding state, or from the Forwarding state to the Blocking state. The trap is not sent if a newRoot trap is sent for the same transition.

Note: On the SmartStack STS16-20D, only ports 17 to 20 support the spanning tree protocol.
