  Convergence Cisco enhanced the original 802.1D specification with features such as Uplink Fast, Backbone Fast, and Port Fast to speed up the convergence time of a bridged network. The drawback is that these mechanisms are proprietary and need additional configuration. Alternate and Backup Port Roles These two port roles correspond to the blocking state of 802.1D. A blocked port is defined as not being the designated or root port. A blocked port receives a more useful BPDU than the one it sends out on its segment. Remember that a port absolutely needs to receive BPDUs in order to stay blocked. RSTP introduces these two roles for this purpose. Rapid Transition to Forwarding State Rapid transition is the most important feature introduced by 802.1w. The legacy STA passively waited for the network to converge before it turned a port into the forwarding state. The achievement of faster convergence was a matter of tuning the conservative default parameters (forward delay and max_age timers) and often put the stability of the network at stake. The new rapid STP is able to actively confirm that a port can safely transition to the forwarding state without having to rely on any timer configuration. There is now a real feedback mechanism that takes place between RSTP-compliant bridges. In order to achieve fast convergence on a port, the protocol relies upon two new variables: edge ports and link type.

• Question 284:

  Which of the port is not part of STP protocol?

  A. Listening
  B. Learning
  C. Forwarding
  D. Discarding
  D. Discarding

• Question 285:

  Which command is used to enable CHAP authentication, with PAP as the fallback method, on a serial interface?

  A. Router(config-if)# ppp authentication chap fallback ppp
  B. Router(config-if)# ppp authentication chap pap
  C. Router(config-if)# authentication ppp chap fallback ppp
  D. Router(config-if)# authentication ppp chap pap
  B. Router(config-if)# ppp authentication chap pap

  ---

  The command "ppp authentication chap pap" command indicates the CHAP authentication is used first. If it fails or is rejected by other side then uses PAP instead. If you want to use PAP first (then CHAP) you can use the "ppp authentication pap chap" command
