Enumerations
4
portStpStateEnum
These are the enumerations for port STP states.
portTaggedModeEnum
This type of data describes the enumerations for modes of port tagging.
TABLE 836 Attributes
Parameters Description
DISABLED The port is not participating in STP. This can occur when the port is
disconnected or STP is disabled on the port.
BLOCKING STP has blocked traffic on this port to prevent a loop.
The device or VLAN can reach the root bridge using another port,
whose state is FORWARDING. When a port is in this state, the port
does not transmit or receive user frames, but the port does continue
to receive STP BPDUs.
LISTENING STP is responding to a topology change and this port is listening for a
BPDU from neighboring bridges in order to determine the new
topology. No user frames are transmitted or received during this state.
LEARNING The port has passed through the LISTENING state and will change to
the FORWARDING state, depending on the results of STP
reconvergence. The port does not transmit or receive user frames
during this state. However, the device can learn the MAC addresses of
frames that the port receives during this state and make
corresponding entries in the MAC table.
PREFORWARDING The preforwarding state.
FORWARDING STP is allowing the port to send and receive frames.
REMOTE_FAULT_NOTIFICATION Topology fault notification.
NONE No state.
