bridge priority STP priority of this RoamAbout switch.
bridge MAC address MAC address of this RoamAbout switch.
bridge hello time Value of the hello timer interval, in seconds, when this RoamAbout switch
is the root or is attempting to become the root.
bridge forward delay Value of the forwarding delay interval, in seconds, when this RoamAbout
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 RoamAbout switch on VLANs for which the switch is
the designated bridge.
topology change time Time period, in seconds, during which BPDUs are transmitted with the
topology change flag set by this RoamAbout 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 Number of times the topology change has occurred.
topology change last recvd.
from
MAC address of the bridge from which the RoamAbout switch last
received a topology change.
dynamic max age transition Number of times the maximum age parameter was changed dynamically.
port BPDU ok count Number of valid port BPDUs received.
msg age expiry count Number of expired messages.
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
Number of similar BPDUs received on a port that need to be processed.
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.
