SPANTREE Messages
Error Message
SPANTREE-2-BLOCK_PVID_LOCAL: Blocking [chars] on [chars]. Inconsistent
local vlan.
Explanation
The spanning-tree port associated with the listed spanning-tree instance and interface
will be held in the spanning-tree blocking state until the port VLAN ID (PVID) inconsistency is
resolved. The listed spanning-tree instance is that of the native VLAN ID of the listed interface. The
first [chars] is the interface, and the second [chars] is the spanning-tree instance.
Recommended Action
Verify that the configuration of the native VLAN ID is consistent on the
interfaces on each end of the IEEE 802.1Q trunk connection. When corrected, spanning tree
automatically unblocks the interfaces, as appropriate.
Error Message
SPANTREE-2-BLOCK_PVID_PEER: Blocking [chars] on [chars]. Inconsistent
peer vlan.
Explanation
The spanning-tree port associated with the listed spanning-tree instance and interface
will be held in the spanning-tree blocking state until the port VLAN ID (PVID) inconsistency is
resolved. The listed spanning-tree instance is that of the native VLAN ID of the interface on the peer
switch to which the listed interface is connected. The first [chars] is the interface, and the second
[chars] is the spanning-tree instance.
Recommended Action
Verify that the configuration of the native VLAN ID is consistent on the
interfaces on each end of the IEEE 802.1Q trunk connection. When interface inconsistencies are
corrected, spanning tree automatically unblocks the interfaces.
Error Message
SPANTREE-2-CHNL_MISCFG: Detected loop due to etherchannel
misconfiguration of [chars] [chars].
Explanation
A misconfiguration of a channel group has been detected. For example, the ports on one
side of the EtherChannel either are not configured to be in the channel or failed to bundle into the
channel, and the other side has successfully bundled the ports into the EtherChannel. The first
[chars] is the port, and the second [chars] is the VLAN.
Recommended Action
Identify the local ports by using the
show interfaces status err-disabled
privileged EXEC command, and then check the EtherChannel configuration on the remote device
by using the
show etherchannel summary
privileged EXEC command on the remote device. After
the configuration is correct, enter the
shutdown
and then
no shutdown
interface configuration
commands on the associated port-channel interfaces.
