SPANTREE_FAST Messages
SPANTREE_FAST Messages
This section contains the spanning-tree fast-convergence message.
Error Message SPANTREE_FAST-7-PORT_FWD_UPLINK: [chars] [chars] moved to Forwarding
(UplinkFast).
Explanation 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.
Recommended Action No action is required.
SPANTREE_VLAN_SW Messages
The section contains the per-VLAN spanning-tree-specific message.
Error Message SPANTREE_VLAN_SW-2-MAX_INSTANCE: Platform limit of [dec] STP instances
exceeded. No instance created for [chars] (port [chars]).
Explanation 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 ID of those VLANs that are unable to have spanning-tree instances
created.
Recommended Action 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 could not be created because of limited
instances.
