The following entries are displayed on this screen:

¾TC Protect

TC Threshold: Enter a number from 1 to 100. It is the maximum number of the

TC-BPDUs received by the switch in a TC Protect Cycle. The default value is 20.

TC Protect Cycle: Enter a value from 1 to 10 to specify the TC Protect Cycle. The default value is 5.

7.5 Application Example for STP Function

¾Network Requirements

zSwitch A, B, C, D and E all support MSTP function.

zA is the central switch.

zB and C are switches in the convergence layer. D, E and F are switches in the access layer.

zThere are 6 VLANs labeled as VLAN101-VLAN106 in the network.

zAll switches run MSTP and belong to the same MST region.

zThe data in VLAN101, 103 and 105 are transmitted in the STP with B as the root bridge. The data in VLAN102, 104 and 106 are transmitted in the STP with C as the root bridge.
