In standard STP mode, which of the following ports on non-root switches forward the BPDUs with TC bits set generated by the root switch?
As shown in the figure, if host A has the ARP cache of host B, host A can ping host B.
On the VRP, when the mkdir test command is run, the system creates a directory named test.
If a device running STP receives an RSTP configuration BPDU, it discards the BPDU.
