(Optional) Display spanning-tree information for the specified interface
(all options except portfast and state available only in privileged EXEC
mode). Enter each interface separated by a space. Ranges are not
supported. Valid interfaces include physical network node interfaces
(NNIs), enhanced network interfaces (ENIs), VLANs, and NNI or ENI
port channels. The VLAN range is 1 to 4094. The port-channel range is
1 to 48.
Spanning Tree Protocol (STP) is not supported on user node
Note
interfaces (UNIs). If you enter a UNI interface ID, no
spanning-tree information is displayed.
(Optional) Display the multiple spanning-tree (MST) region
configuration and status (available only in privileged EXEC mode).
The keywords have these meanings:
digest—(Optional) Display the MD5 digest included in the current
•
MST configuration identifier (MSTCI). Two separate digests, one for
standard and one for prestandard switches, appear (available only in
privileged EXEC mode).
The terminology was updated for the implementation of the IEEE
standard, and the txholdcount field was added.
The new master role appears for boundary ports.
The word pre-standard or Pre-STD appears when an IEEE standard
bridge sends prestandard BPDUs on a port.
The word pre-standard (config) or Pre-STD-Cf appears when a port
has been configured to send prestandard BPDUs and no prestandard
BPDU has been received on that port.
The word pre-standard (rcvd) or Pre-STD-Rx appears when a
prestandard BPDU has been received on a port that has not been
configured to send prestandard BPDUs.
A dispute flag appears when a designated port receives inferior
designated information until the port returns to the forwarding state
or ceases to be designated.
• instance-id—You can specify a single instance ID, a range of IDs
separated by a hyphen, or a series of IDs separated by a comma. The
range is 1 to 4094. The display shows the number of currently
configured instances.
interface interface-id—(Optional) Valid interfaces include VLANs,
•
physical NNIs and NNI port channels, and physical ENIs and ENI
port channels. STP is not supported on UNIs.
The VLAN range is 1 to 4094. The port-channel range is 1 to 48.
• detail—(Optional) Display detailed information for the instance or
interface.
(Optional) Display the default path cost method (available only in
privileged EXEC mode).
(Optional) Display root switch status and configuration (all keywords
available only in privileged EXEC mode).
