SPANTREE Messages
SPANTREE-7
Error Message SPANTREE-7-BLOCK_PORT_TYPE: Blocking [char] on [char]. Inconsistent
port type.
Explanation
The listed interface is being held in spanning tree blocking state until the port type
inconsistency is resolved. The port ID is [char].
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 type (ISL or 802.1Q). When these
parameters are consistent, spanning tree automatically unblocks the interface.
Error Message SPANTREE-7-RECV_1Q_NON_TRUNK: Received 802.1Q BPDU on non trunk [char]
[char].
Explanation
An SSTP BPDU was received on the listed interface, which is not an operational
trunking interface. The interface ID is [char].
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 type (none, ISL, or 802.1Q). Once
these parameters are consistent, spanning tree automatically unblocks the interface.
