SPANTREE_FAST Messages

This section contains the spanning-tree fast-convergence message.

SPANTREE_FAST-7-PORT_FWD_UPLINK: [chars] [chars] moved to Forwarding (UplinkFast).

Explanation This message means that the listed interface has been selected as the new path to the root switch for the listed spanning-tree instance. The first [chars] is the spanning-tree instance, and the second [chars] is the interface.

Response No action is required.

SPANTREE_VLAN_SWITCH Messages

The section contains the per-VLAN spanning-tree-specific message.

SPANTREE_VLAN_SW-2-MAX_INSTANCE: Platform limit of [dec] STP instances exceeded. No instance created for

[chars] (port [chars]).

Explanation This message means that the number of currently active VLAN spanning-tree instances has reached a platform-specific limit. No additional VLAN instances will be created until the number of existing instances drops below the platform limit. [dec] is the spanning-tree instance limit, and the first [chars] is the smallest VLAN number of those VLANs that are unable to have STP instances created.

Response Reduce the number of currently active spanning-tree instances by either disabling some of the currently active spanning-tree instances or deleting the VLANs associated with them. You must manually enable the spanning trees that generate this message.

STORM_CONTROL Messages

This section contains the storm control message.

STORM_CONTROL-2-SHUTDOWN: Storm control shut down [chars].

Explanation This message means that excessive traffic has been detected on a port that has been configured to be shut down if a storm event is detected. [chars] is the physical interface.

Response When the source of the packet storm has been fixed, re-enable the port by using the no shutdown interface configuration command.
