Each time that you make a VLAN change in a VTP device, the configuration revision is incremented by one.

A network running STP uses BPDUs to communicate in between switches (bridges). Switches become aware of each other and of the topology that interconnects them. After a Root Bridge is elected, BPDUs are generated by the root and are relayed down through the spanning-tree topology.

To maintain an efficient topology, the placement of the Root Bridge must be predictable. Hopefully, you configured one switch to become the Root Bridge and a second one to be the secondary root. What happens when a “foreign” or rogue switch is connected to the network, and that switch suddenly is capable of becoming the Root Bridge? Cisco added two STP features that help prevent the unexpected: Root guard and BPDU guard. rk B

In a valid PortFast configuration, configuration BPDUs should never be received, so Cisco switches supports a feature called asPortFast BPDU Guard, which shuts down a PortFastenabled port in the event a BPDU is received. This feature ensures that a bridging loop cannot be formed because the switch's shutting down the port removes the possibility of a loop formation.

The loop guard feature is enabled on a per-port basis. However, as long as it blocks the port on the STP level, loop guard blocks inconsistent ports on a per-VLAN basis (because of per-VLAN STP). That is, if BPDUs are not received on the trunk port for only one particular VLAN, only that VLAN is blocked (moved to loop-inconsistent STP state). ork etw

STP has a drawback that its convergence is low which is very important in switched network. To overcome this problem, Rapid Spanning Tree Protocol (RSTP) with IEEE standard 802.1w is evolved which significantly reduces the convergence time after a topology change occurs in the network. While STP can take 30 to 50 seconds to transit from a blocking state to a forwarding of a physical link failure. ls ullsstate, RSTP is typically able ulls to respond in less than 10ulseconds ulls

IP Source Guard uses the DHCP snooping binding’s database. When IP Source Guard is enabled, the switch drops the incoming packets that do not match a binding in the binding’s database. IP Source Guard can be configured to enforce just the source IP address or both the source IP address and source MAC address.

Each time that you make a VLAN change in a VTP device, the configuration revision is incremented by one.

A network running STP uses BPDUs to communicate in between switches (bridges). Switches become aware of each other and of the topology that interconnects them. After a Root Bridge is elected, BPDUs are generated by the root and are relayed down through the spanning-tree topology. Eventually, all switches in the STP domain receive the root’s BPDUs so that the s s l l network converges and aBustable lls lls loop-free topology kforms. Bull k Bu k k Bu

To maintain an efficient topology, the placement of the Root Bridge must be predictable. Hopefully, you configured one switch to become the Root Bridge and a second one to be the secondary root. What happens when a “foreign” or rogue switch is connected to the network, and that switch suddenly is capable of becoming the Root Bridge? Cisco added two STP features that help prevent the unexpected: Root guard and BPDU guard. rk B

In a valid PortFast configuration, configuration BPDUs should never be received, so Cisco switches supports a feature called asPortFast BPDU Guard, which shuts down a PortFastenabled port in the event a BPDU is received. This feature ensures that a bridging loop cannot be formed because the switch's shutting down the port removes the possibility of a loop formation.

The loop guard feature is enabled on a per-port basis. However, as long as it blocks the port on the STP level, loop guard blocks inconsistent ports on a per-VLAN basis (because of per-VLAN STP). That is, if BPDUs are not received on the trunk port for only one particular VLAN, only that VLAN is blocked (moved to loop-inconsistent STP state). ork etw

STP has a drawback that its convergence is low which is very important in switched network. To overcome this problem, Rapid Spanning Tree Protocol (RSTP) with IEEE standard 802.1w is evolved which significantly reduces the convergence time after a topology change occurs in the network. While STP can take 30 to 50 seconds to transit from a blocking state to a forwarding of a physical link failure. ls ullsstate, RSTP is typically able ulls to respond in less than 10ulseconds ulls

IP Source Guard uses the DHCP snooping binding’s database. When IP Source Guard is enabled, the switch drops the incoming packets that do not match a binding in the binding’s database. IP Source Guard can be configured to enforce just the source IP address or both the source IP address and source MAC address.
