Flashcards in Chapter 3 Deck (14):
1

STP port state Blocking

Not forwarding frames listening to BPDUs

2

STP port state Listening

Receving and transmitting BPDUs, discovering the topology

3

STP port state Learning

Populating the CAM table with MAC addresses

4

STP port state Forwarding

Actively participating in frame forwarding

5

STP port state Disabled

Not participating in STP

6

STP Max Age Timer

Length of time to wait to hear from root - 20 sec default

7

STP Forward Delay Timer

Amount of time spent at both listening and learning states - 15 seconds default

8

RSTP port state Discarding

prevents the forwarding of data frames, breaking layer 2 loops

9

RSTP port state Learning

accepts data frames to populate the MAC table to limit flooding of unknown unicast frames

10

RSTP port state Forwarding

forwarding switch ports determine the topology, after a change in topology or sync only after a proposal and agreement process

11

RSTP Link type p2p

port is operating in full duplex mode the port is connected to a single switch device at the other end of the link

12

RSTP Link type shared

Port is operating in half duplex mode, the port is connect to a shared media where multiple switches might exist ex hub

13

RSTP edge port

is a switch port that is never intended to be connected to another switch device

14

RSTP Topology Change

Only non-edge ports that are moving the the forwarding state cause a topology change. A port that is moving to blocking does not generate a TC
