When two interfaces are disabled and added to Spanning Tree Protocol (STP) in the VLAN configuration, the second interface stays in 'blocked' STP state.
The blocked port does not send out data.
At least two interfaces exist in disabled state, added to STP.
If the STP flag is disabled and re-enabled on the blocked interface, after the port is enabled, the port STP status is re-evaluated to the correct state.
Spanning Tree Protocol (STP) now checks for the disabled state of the port before adding it as an STP member.
