If you do not specify any port, this command displays the spanning tree information for all ports.
The displayed information is sorted by port name.
If you specify a port list, this command displays the spanning tree information for the specified ports.
The displayed information is sorted by port name.
In MSTP mode, follow these guidelines:
If you do not specify any MSTI or port, this command displays the spanning tree information of all
MSTIs on all ports. The displayed information is sorted by MSTI ID and by port name in each MSTI.
If you specify an MSTI but not a port, this command displays the spanning tree information on all
ports in that MSTI. The displayed information is sorted by port name.
If you specify some ports but not an MSTI, this command displays the spanning tree information of
all MSTIs on the specified ports. The displayed information is sorted by MSTI ID and by port name in
each MSTI.
If you specify both an MSTI ID and a port list, this command displays the spanning tree information
on the specified ports in the specified MSTI. The displayed information is sorted by port name.
