Error Message SPANTREE_VLAN_SHIM-2-MAX_INSTANCE: Platform limit of [dec] STP
instances exceeded. No instance created for [chars] (port [chars]).

STORM_CONTROL Messages

Error Message STORM_CONTROL-3-FILTERED: A [chars] storm detected on [chars]. A
packet filter action has been applied on the interface.
Error Message STORM_CONTROL-3-SHUTDOWN: A packet storm was detected on [chars]. The
interface has been disabled.
OL-23408-01
Explanation The number of VLAN spanning-tree instances has reached the maximum limit. No
additional VLAN instances will be created until the number of instances drops below the maximum
limit. [dec] is the maximum, the first [chars] is the VLAN for which an STP instance is not created,
and the second [chars] is the port number.
For example, when you are configuring spanning tree and the maximum is 128 instances:
If the switch has already created 128 instances and you enter the vlan 200-1000 global interface
–
configuration command, the first [chars] is 200, and an STP instance for VLAN 200 is not
created. STP instances are also not created for the remainder of the VLANs in the range.
If the switch has already created 100 instances and you enter the vlan 200-1000 global interface
–
configuration command, the first [chars] is 228. The switch creates STP instances for VLAN
200 to VLAN 227, but not for VLAN 228. STP instances are also not created for the remainder
of the VLANs in the range.
Recommended Action Reduce the number of active spanning-tree instances by either disabling some
or deleting the VLANs associated with them. To create STP instances, manually create them. If you
do not, the switch automatically creates an STP instances when a VLAN is created.
For example, if the switch has already created 128 instances and you want to create an STP instance
for VLAN 200, remove a spanning-tree instance with one of these commands:
To delete one of the VLANs, enter the no vlan vlan-id configuration command.
–
To disable spanning tree on a per-VLAN basis. enter the no spanning-tree vlan-id
–
configuration command.
Enter the spanning-tree 200 configuration command to create an instance for VLAN 200.
Explanation The amount of traffic detected on the interface has exceeded the configured threshold
values. The system is filtering the excess traffic. The first [chars] is the traffic type, and the second
[chars] is the interface.
Determine and fix the root cause of the excessive traffic on the interface.
Recommended Action
The amount of traffic detected on the interface has exceeded the configured threshold
Explanation
values. Since the interface is configured to shutdown if a packet storm event is detected, it has been
placed in an error-disabled state. [chars] is the affected interface.
You can enable error-disabled recovery by using the errdisable recovery
Recommended Action
global configuration command to automatically re-enable the interface. You should determine and
fix the root cause of the excessive traffic on the interface.
