In STP or RSTP mode, the command output is sorted by port name.
•
If you do not specify a port, this command applies to all ports.
•
If you specify a port list, this command applies to the specified ports.
In PVST mode, the command output is sorted by VLAN ID and by port name in each VLAN.
•
If you do not specify a VLAN or port, this command applies to all ports in all VLANs.
•
If you only specify a VLAN list but not a port, this command applies to all ports in the specified
VLANs.
•
If you only specify a port list but not a VLAN, this command applies to the specified ports in all
VLANs.
•
If you specify both a VLAN list and a port list, this command applies to the ports in the specified
VLANs.
In MSTP mode, the command output is sorted by MSTI ID and by port name in each MSTI.
•
If you do not specify an MSTI or port, this command applies to all MSTIs on all ports.
•
If you specify an MSTI list but not a port, this command applies to all ports in the specified
MSTIs.
•
If you specify a port list but not an MSTI, this command applies to all MSTIs on the specified
ports.
•
If you specify both an MSTI list and a port list, this command applies to the specified ports in the
specified MSTIs.
