Field

Description

bridge forward delay

Value of the forwarding delay interval, in seconds, when this switch is the root or is

attempting to become the root.

 

topology change initiator

Port number that initiated the most recent topology change.

last topology change occurred

System time when the most recent topology change occurred.

topology change

Value of the topology change flag in configuration BPDUs to be transmitted by this

switch on VLANs for which the switch is the designated bridge.

 

 

Time period, in seconds, during which BPDUs are transmitted with the topology

topology change time

change flag set by this switch when it is the root bridge, after detection of a topology

change. It is equal to the sum of the switch’s maximum age and forwarding delay

 

 

parameters.

 

 

topology change detected

Indicates whether a topology change has been detected by the switch.

 

 

topology change count

link loading

Indicates whether the link is oversubscribed.

 

 

BPDU in processing

Indicates whether BPDUs are currently being processed.

 

 

num of similar BPDU’s to process

received_inferior_bpdu

Indicates whether the port has received an inferior BPDU or a response to a Root

Link Query (RLQ) BPDU.

 

next state

Port state before it is set by STP.

src MAC count

Number of BPDUs with the same source MAC address.

total src MAC count

Number of BPDUs with all the source MAC addresses.

curr_src_mac

Source MAC address of the current received BPDU.

next_src_mac

Other source MAC address from a different source.
