32 Cisco Systems Intelligent Gigabit Ethernet Switch Module for the IBM Eserver BladeCenter System Message Guide
SPAN-3-UNKN_ERR: An internal error occurred during a SPAN operation.
Explanation This message means that SPAN detected an error in its internal operation.
Response The error might be transient. Try the SPAN operation again. If a second attempt also fails,
reload the switch by using the reload privileged EXEC command to complete the operation.
SPAN-3-UNKN_ERR_PORT: An internal error occurred when configuring SPAN on port [chars].
Explanation This message means that SPAN detected an error in its internal operation. [chars] is the
interface.
Response The error might be transient. Try the SPAN operation again. If the second attempt also fails,
reload the switch by using the reload privileged EXEC command to complete the operation.
SPANTREE Messages
This section contains the spanning-tree messages.
SPANTREE-2-BLOCK_BPDUGUARD: Received BPDU on port [chars] with BPDU Guard enabled. Disabling port.
Explanation This message means that a bridge protocol data unit (BPDU) was received on the interface
specified in the error message that has the spanning-tree BPDU guard feature enabled. As a result, the
interface was administratively shut down. [chars] is the interface.
Response Either remove the device sending BPDUs, or disable the BPDU guard feature. The BPDU
guard feature can be locally configured on the interface or globally configured on all ports that have Port
Fast enabled. After the conflict has been resolved, re-enable the interface by entering the no shutdown
interface configuration command.
SPANTREE-2-BLOCK-PVID-LOCAL: Blocking [chars] on [chars] Inconsistent local vlan.
Explanation This message means that the spanning-tree port associated with the listed spanning-tree
instance and interface will be held in the spanning-tree blocking state until the per-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.
Response Verify that the configuration of the native VLAN ID is consistent on the interfaces on each end
of the 802.1Q trunk connection. When corrected, spanning tree automatically unblocks the interfaces, as
appropriate.
SPANTREE-2-BLOCK-PVID-PEER: Blocking on [chars] [chars]. Inconsistent peer vlan.
Explanation This message means that 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.
Response Verify that the configuration of the native VLAN ID is consistent on the interfaces on each end
of the 802.1Q trunk connection. When it is corrected, spanning tree automatically unblocks the interfaces,
as appropriate.
