Description
Use display stp to display the spanning tree status and statistics.
Based on the spanning tree status and statistics, you can analyze and maintain the network topology or
check whether spanning tree is working properly.
In STP/RSTP mode, follow these guidelines:
• 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.
In PVST mode, follow these guidelines:
If you do not specify any VLAN or port, this command displays the spanning tree information of all
•
VLANs on all ports. The displayed information is sorted by VLAN ID and by port name in each
VLAN.
If you specify a VLAN but not a port, this command displays the spanning tree information on all
•
ports in that VLAN. The displayed information is sorted by port name.
If you specify some ports but not any VLAN, this command displays the spanning tree information
•
of all VLANs on the specified ports. The displayed information is sorted by VLAN ID, and by port
name in each VLAN.
If you specify both a VLAN ID and a port list, this command displays the spanning tree information
•
on the specified ports in the specified VLAN. The displayed information is sorted by port name.
