Port STP configuration groups
The Spanning Tree Protocol (STP) eliminates Layer 2 loops in networks by selectively blocking some
ports and allowing other ports to forward traffic based on global (bridge) and local (port)
parameters you can configure.
Port STP table
The following table applies to all other FastIron and NetIron devices, except the FastIron X series.
These devices use snIfStpTable. The snIfStpTable replaces snPortStpTable.
NOTE
The following table is not supported on the Brocade MLXe, Brocade NetIron MLX, Brocade NetIron
XMR, Brocade NetIron CES, and Brocade NetIron CER series devices.
Name, OID, and syntax Access Description
snPortStpTable
brcdIp.1.1.3.5.1 None A specific snPortStpTable consists of a number of switch ports. This
table only exists if
“snVLanByPortTable” on page 303 exists and
“snVLanByPortStpMode” on page 304 is enabled for each VLAN.
snPortStpVLanId
brcdIp.1.1.3.5.1.1.1
Syntax: Integer Read-only Shows the VLAN ID of the VLAN switch community.
Valid values: 1 – 65535
snPortStpPortNum
brcdIp.1.1.3.5.1.1.2
Syntax: Integer32 Read-only Shows the port number of the switch:
•
Bit 0 to 7 – Port number.
•
Bit 8 to 11 – Slot number (slot for chassis only).
snPortStpPortPriority
brcdIp.1.1.3.5.1.1.3
Syntax: Integer Read-write Shows the value of the priority field, which is contained in the first
(in network byte order) octet of the Port ID. The second octet of the
Port ID is given by the value of dot1dStpPort. The two octets
combine to form the identity of the root bridge in a spanning tree
(instance of STP). The bridge with the lowest value has the highest
priority and is the root.
Valid values: 8 – 255
