three。 Modify STP (spanning Tree Protocol)

1. Modify on sw1,sw2,sw3

Display stp looks at the stp of sw1,sw2,sw3, identifies the root switch and non-root switch, and finds the blocking port (the blocking port is ALTE)

It is found here that the blocking port is Eth0/0/13,sw2 as the root switch and sw1 as the non-root switch. In order to decompress the switch, sw3 is set as the root switch. The configuration is as follows:

Stp priorty 0 modifies priority to 0 (the smaller the stp priority, the higher the priority)

Then type display stp to see which is the root switch and the non-root switch.

two。 Modify on sw4,sw5,sw6

Display stp looks at the stp of sw1,sw2,sw3, identifies the root switch and non-root switch, and finds the blocking port (the blocking port is ALTE)

It is found here that the blocking port is Eth0/0/13,sw2 as the root switch and sw1 as the non-root switch. In order to decompress the switch, sw3 is set as the root switch. The configuration is as follows:

Stp priorty 0 modifies priority to 0 (the smaller the stp priority, the higher the priority)

Then type display stp to see which is the root switch and the non-root switch.

seven. Verification, test

Access to other hosts with any PC to achieve network interworking

Then enter shutdown into any port between the route and the switch to see if it can still be connected (intranet).
