D Spanning Tree Protocol Introduction When Spanning Tree Protocol determines a por t should be transitioned to the forwarding state, the following occurs: • • • • • • The port is put into the listening state where it receives Bridge Protocol Data Units (BPDUs) and passes them to the GbE Interconnect Switch’s CPU.
Spanning Tree Protocol • Does not transmit BPDUs received from the CPU. • Receives and responds to netw ork management messages. Figure D-1: Blocking State Listening State The listening state is the first transition for a port from the blocking state.
Spanning Tree Protocol A port in the listening state does the following: • • • • • • Discards frames received from the network segmen t to which it is attached. Discards packets sent from another port on the switch for forwarding. Does not add addresses to its forwarding database.
Spanning Tree Protocol Learning State A port in the learning state prepares to particip ate in frame forwarding. The port enters the learning state from the listening state. A port in the learning state does the following: • • • • • • Discards frames received from the network segmen t to which it is attached.
Spanning Tree Protocol Figure D-3: Learning State Forwarding State A port in the forwarding state forwards packets. The port enters the forwarding state from the learning state when the forward delay timer expires.
Spanning Tree Protocol A port in the forwarding state does the following: • • • • • Forwards packets received from the network segment to which it is attached. Forwards packets sent from another port on the switch for forwarding. Incorporates station location inform ation into its address database.
Spanning Tree Protocol Disabled State A port in the disabled state does not participate in frame forwarding or STP. A port in the disabled state is virtually non-operational. A disabled port does the following: • • • • • • Discards packets received from the network segmen t to which it is attached.

Spanning Tree Protocol Troubleshooting STP This section describes se veral troubleshooting tips. Spanning Tree Protocol Failure A failure in the STP generally leads to a bridging loop. A bridging loop i n an STP environment comes from a port that should be in the blocking state, but is forwarding packets.
Spanning Tree Protocol Full/Half Duplex Mismatch A mismatch in the duplex state of two ports is a very common configuration error for a point- to-point link.
Spanning Tree Protocol Unidire ctional L ink Unidirectional links can be caused by an undetected failure in one side of a fiber cable, or a problem with a ports transceiver. Any failure that allows a link to remain up while providing one-way communication is very dangerous for STP.
Spanning Tree Protocol Packet Corruption Packet corruption can also lead to Spanning Tr ee Protocol failure. If a link is experiencing a high rate of physical errors, a large number of consecutive BPDUs can be dropped and a port in the blocking state would transition to the forwarding state.
Spanning Tree Protocol Avoiding Trouble Below are some tips for avoiding trouble. Know Where the Root is Located Although the STP can elect a root bridge, a we ll-designed network will have an identifiable root for each VLAN. Careful setup of the STP pa rameters will lead to the selection of this best interconnect switch as the root for each VLAN.

The switches C and D have redundant links to the backbone switches A and B using trunks.
E SNMP/RMON MIBs Support Introduction Management and statistics in formation is stored in the interconnect switch in the Management Information Base (MIB). The in terconnect switch supports several standard MIBs. Values for MIB objects can be retrieve d with any SNMP-based network management software.
SNMP/RMON MIBs Support Use an SNMP manager, such as HP OpenView or IBM Tivoli NetView, to acce ss the enterprise-specific MIBs. Compile the MIBs into the MIB database and then use a MIB browser to navigate through them.
SNMP/RMON MIBs Support • vesubio.mib — swL2BwMgmt—Management of the ingress and egress bandwidth — swL2CosMgmt—Management of Class of Service — swL2PortSecurityMgmt—Man agement of port s.
