If they are inconsistent, modify the configurations of the local port. If the problem persists, contact H3C Support. Verify that packets are not mistakenly filtered out by ACLs: Examine the ACL and QoS policy configuration for packet filtering on the port, on the VLAN of the port, or globally. - Page 19 Execute the display stp brief command to determine whether STP sets the state of the port to discarding. When the port is in discarding state, it cannot forward traffic. H3C recommends disabling STP on the port, or configuring the port as an edge port if the port is connected to a terminal device.
