RSTP switch port states:
1.
Blocking
- A port that would cause a switching loop if it were active. No user data is sent or
received over a blocking port, but it may go into forwarding mode if the other links in use fail
and the spanning tree algorithm determines the port may transition to the forwarding state.
BPDU data is still received in blocking state. Prevents the use of looped paths.
2.
Listening
- The switch processes BPDUs and awaits possible new information that would
cause it to return to the blocking state. It does not populate the MAC address table and it does
not forward frames.
3.
Learning
- While the port does not yet forward frames it does learn source addresses from
frames received and adds them to the filtering database (switching database). It populates the
MAC Address table, but does not forward frames.
4.
Forwarding
- A port receiving and sending data, normal operation. RSTP still monitors
incoming BPDUs that would indicate it should return to the blocking state to prevent a loop
.
The example of Configuration: The priority of network bridge is “32768”
，
If there did not have network
ID less than itself, itself is root network bridge. There did not have same network ID in network. Every 2 seconds,
the network bridge will transmit BPDU message to all appoint port. If did not receive BPDU message more than
20 seconds, it realized port invalid, will calculate the status of network bridge again. Each status exchange for
each other if need to transmit, need to wait 15 seconds.
6.7 Access Profile
6.7.1Login Settings
Enterprise usually required two different person to monitor device and manage system/ network . The
authority need to separate. Monitor person was in charge of monitor work, system/network person was in charge
of system/work management. The switch provided
classification management: Administrator authority
and Observer authority. Observer just had authority to check the status of switch. Administrator had
the authority to configure the parameters of the switch.
Index
User index indicates which group of users. There are three user indexes in drop-down list.
Access level:
administrator
：
