show spanning-tree Chapter 2 Catalyst 3560 Switch Cisco IOS Commands mst [configuration [digest]] [instance-id [detail | interface interface-id [detail]] (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 transmit 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 transmit 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 physical ports, VLANs, and port channels. 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. pathcost method (Optional) Display the default path cost method (available only in privileged EXEC mode). root [address | cost | detail | forward-time | hello-time | id | max-age | port | priority [system-id]] (Optional) Display root switch status and configuration (all keywords available only in privileged EXEC mode). summary [totals] (Optional) Display a summary of port states or the total lines of the spanning-tree state section. The words IEEE Standard identify the MST version running on a switch. uplinkfast (Optional) Display spanning-tree UplinkFast status. vlan vlan-id [active [detail] | backbonefast | blockedports | bridge [address | detail | forward-time | hello-time | id | max-age | priority [system-id] | protocol] (Optional) Display spanning-tree information for the specified VLAN (some keywords available only in privileged EXEC mode). You can specify a single VLAN identified by VLAN ID number, a range of VLANs separated by a hyphen, or a series of VLANs separated by a comma. The range is 1 to 4094. 2-520 Catalyst 3560 Switch Command Reference 78-16405-05

(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
txholdcoun
t field was added.
The new master role appears for boundary ports.
The word
pre-standard
or
