The RRPP ring main ring 1 is formed on the customer LAN switches SWA, SWB, and SWC, which can be known from the above information

A customer wants to deploy 802.1X in the local area network to improve access security. At the same time, the customer wants to temporarily close the illegal packets received on the port for 5 minutes through the port security feature to prevent illegal users from accessing the network. The following can be used Which features are implemented

Regarding the relationship between RSTP and STP, the correct statement is

The customer's six switches SWA, SWB, SWC, SWD, SWE, and SWF are connected together through the LAN to form an RRPP ring. Check the RRPP status on SWB as follows:
<SWB>dis rrpp verbose domain 1
Domain ID: 1
Ring ID: 1
Ring Level: 0
Node Mode: Transit
Ring state:-
Enable Status: YesActive Status: Yes
Primary port: GigabitEthernet2/0/1 Port status: UP
Secondary port: GigabitEthernet2/0/2 Port status: UP
Ring ID: 2
Ring Level: 1
Node Mode: Edge
Ring state:-
Enable Status: YesActive Status: Yes
Common port: GigabitEthernet2/0/1 Port status: UP
GigabitEthernet2/0/2 Port status: UP
Edge port: GigabitEthernet2/0/3 Port status: UP
Ring ID: 3
Ring Level: 1
Node Mode: Edge
Ring state:-
Enable Status: YesActive Status: Yes
Common port: GigabitEthernet2/0/1 Port status: UP
GigabitEthernet2/0/2 Port status: UP
Edge port: GigabitEthernet2/0/4 Port status: UP
Know from the above information

The customer LAN switches SWA, SWB, and SWC form the RRPP ring main ring 1, and the switch SWB has the following configuration information:
[SWB]rrpp domain 1
[SWB-rrpp-domain1]ring 1 node-mode transit primary-port gigabitethernet 2/0/1 secondary-port gigabitethernet 2/0/2 level 0
If the switch SWA is the master node of primary ring 1, if the switch SWB port GigabitEthem2/0/1 fails, you can know from the above information
