LABEL DESCRIPTION
BridgeMaxAge This field displays the maximum time (in seconds) the OLT can wait without
receiving a configuration message before attempting to reconfigure.
BridgeHelloTime This field displays the time interval (in seconds) at which the OLT transmits a
configuration message.
BridgeForwardDelay This field displays the time (in seconds) the OLT will wait before changing states
(that is, listening to learning to forwarding).
BridgeMaxHops This field displays the number of hops (in seconds) in an MSTP region before the
BPDU is discarded and the port information is aged.
TransmissionLimit This field displays the maximum number of BPDUs that can be transmitted in the
interval specified by BridgeHelloTime.
ForceVersion This field indicates whether BPDUs are RSTP (a value less than 3) or MSTP (a value
greater than or equal to 3).
MST Configuration ID
Format Selector This field displays zero, which indicates the use of the fields below.
Configuration Name This field displays the configuration name for this MST region.
Revision Number This field displays the revision number for this MST region.
Configuration Digest A configuration digest is generated from the VLAN-MSTI mapping information.
This field displays the 16-octet signature that is included in an MSTP BPDU. This
field displays the digest when MSTP is activated on the system.
msti This field displays the MSTI ID.
vlans mapped This field displays which VLANs are mapped to an MSTI.
