SPANTREE Messages
Error Message No action is required.SPANTREE-6-PORTDEL_ALL_VLANS: [chars] deleted from
all Vlans
Explanation The interface has been deleted from all VLANs. [chars] is the deleted interface.
Recommended Action No action is required.
Error Message SPANTREE-6-PORT_STATE: Port [chars] instance [dec] moving from [chars]
to [chars].
Explanation The port state changed. The first [chars] is the interface name. [dec] is the spanning-tree
instance ID. The second [chars] is the old state (such as listening, learning, or for warding, and so
forth), and the third [chars] is the new state.
Recommended Action No action is required.
Error Message SPANTREE-7-BLOCK_PORT_TYPE: Blocking [chars] on [chars]. Inconsistent
port type.
Explanation The listed interface is being held in the spanning-tree blocking state until the port-type
inconsistency is resolved. The first [chars] is the interface, and the second [chars] is the
spanning-tree instance.
Recommended Action Verify that the configuration and operational states of the listed interface and
those of the interface to which it is connected are in the same mode (access or trunk). If the mode
is trunk, verify that both interfaces have the same encapsulation (ISL or IEEE 802.1Q). When these
parameters are consistent, spanning tree automatically unblocks the interface.
Error Message SPANTREE-7-PORTDEL_SUCCESS: [chars] deleted from Vlan [dec].
Explanation The interface has been deleted from VLAN. [chars] is the interface, and [dec] is the
VLAN ID.
Recommended Action No action is required.
Error Message SPANTREE-7-RECV_1Q_NON_TRUNK: Received 802.1Q BPDU on non trunk
[chars] [chars].
Explanation An STP BPDU was received on the listed interface, which is not an operational trunking
interface. The first [chars] is the port name, and the second [chars] is the VLAN name.
Recommended Action Verify that the configuration and operational state of the listed interface and
that of the interface to which it is connected are in the same mode (access or trunk). If the mode is
trunk, verify that both interfaces have the same encapsulation (none, ISL, or IEEE 802.1Q). When
these parameters are consistent, spanning tree automatically unblocks the interface.
